HAS ADOPTED THIS DIRECTIVE:     TITLE I General provisions   Article 1 For the purposes of this Directive, Community inland waterways shall be classified as follows:    - Zones 1 and 2 : the waterways listed in Chapter 1 of Annex I,       - Zone 3 : the waterways listed in Chapter 2 of Annex I,       - Zone 4 : all other Community waterways.         Zone R covers those of the abovementioned waterways for which inspection certificates are to be issued in accordance with Article 22 of the Revised Convention for the Navigation of the Rhine as this Article is worded when the Directive is adopted.    Article 2 1. This Directive shall apply to:    - vessels having a total dead weight of 15 tonnes or more, or vessels not intended for the carriage of goods having a displacement of 15 cubic metres or more,       - tugs and pusher craft, including those with a displacement of less than 15 cubic metres, provided that they have been built to tow or push or to move vessels alongside.         2. The following are excluded from this Directive:    - passenger vessels,       - ferries,       - floating equipment,       - floating establishments and installations including those being moved from one location to another,       - pleasure craft,       - service craft belonging to supervisory authorities and fire-service vessels,       - naval vessels,       - sea-going vessels, including sea-going tugs and pusher craft operating or based on tidal waters or temporarily on inland waterways, carrying a valid navigation permit,       - tugs and pusher craft with a displacement of less than 15 cubic metres which have been built to tow, push or move alongside only vessels with a displacement of less than 15 cubic metres.           Article 3 Vessels operating on the Community waterways listed in Article 1 shall carry:    - a certificate issued pursuant to Article 22 of the Revised Convention for the Navigation of the Rhine, when operating on a Zone R waterway,       - a Community inland-navigation certificate issued to vessels complying with the technical requirements of Annex II, when operating on waterways of other zones.         The Community certificate shall be drawn up following the model given in Annex III and shall be issued in accordance with this Directive.    Article 4 1. All vessels carrying a valid certificate issued pursuant to Article 22 of the Revised Convention for the Navigation of the Rhine may navigate on Community waterways carrying only that certificate.  2. However, all vessels carrying the certificate referred to in paragraph 1 shall also be provided with a supplementary inland-navigation certificate (supplementary Community certificate):    - when operating on Zone 3 and 4 waterways, if they wish to take advantage of the reduction in technical requirements on these waterways,       - when operating on Zone 1 and 2 waterways, if the Member State concerned has adopted additional technical requirements for these waterways, in accordance with Article 5.         The supplementary Community certificate shall be drawn up following the model shown in Annex IV and shall be issued by the competent national authorities on production of the certificate referred to in paragraph 1 and under the conditions laid down by them.    Article 5 1. Each Member State may, subject to the requirements of the Revised Convention for the Navigation of the Rhine and after consulting the Commission, adopt technical requirements additional to those in Annex II for vessels operating on Zone 1 and 2 waterways within its territory.  Such additional requirements shall be communicated to the other Member States and the Commission at least six months before their entry into force, unless they were already in force on 21 January 1977.  2. Compliance by the vessels with these additional requirements shall be specified in the Community certificate referred to in Article 3 or, where Article 4 (2) applies, in the supplementary Community certificate.    Article 6 Any vessel carrying a certificate issued pursuant to the Regulation for the transport of dangerous substances on the Rhine (ADNR) may carry dangerous goods throughout the territory of the Community under the conditions stated in that certificate.   Any Member State may require that vessels which do not carry an ADNR certificate shall be authorized to carry dangerous goods within its territory only if the vessels comply with requirements additional to those set out in this Directive. Such requirements shall be notified to the Commission and the other Member States.    Article 7 1. Member States may exempt from the application of all or part of this Directive:    (a) vessels operating on navigable waterways not linked, by inland waterway, to the waterways of other Member States;       (b) vessels having a dead weight not exceeding 350 tonnes which were laid down before 1 January 1950 and operate exclusively on a national waterway.         2. Member States may authorize in respect of navigation on their national waterways exemptions from one or more provisions of this Directive for limited journeys of local interest or in harbour areas. The derogations in question and the journeys or area for which they are valid shall be specified in the vessel's certificate.  3. The Commission shall be notified of derogations adopted pursuant to this Article.  4. Any Member State which, as a result of derogations granted in accordance with paragraphs 1 and 2, has no vessels subject to the provisions of this Directive operating on its waterways shall not be required to comply with Articles 9, 10 and 12.    TITLE II Conditions and rules for issuing Community inland waterway certificates   Article 8 1. The Community certificate shall be issued to vessels laid down as from 1 January 1985 following a technical inspection carried out prior to the vessel being put into service and intended to check whether the vessel complies with the technical requirements laid down in Annex II.  2. The Community certificate shall be issued to vessels in service on 1 January 1985 and to vessels laid down before that date following a technical inspection to be carried out between 1 January 1986 and 1 July 1998, in accordance with a timetable to be laid down by each Member State, to check that the vessel complies with the technical requirements laid down in Annex II. This timetable shall be notified to the Commission and the other Member States.  However, in the case of vessels navigating exclusively on its national network and laid down before 1 January 1970, any Member State may decide to extend by seven years the period during which the technical inspection shall be carried out.  3. Compliance of a vessel with the additional requirements referred to in Article 5 shall, where appropriate, be checked during the technical inspections provided for in the preceding paragraphs, or during a technical inspection carried out at the request of the vessel's owner.    Article 9 The Community certificate shall be issued by the competent national authority of the Member State in which the vessel is registered or, failing that, of the Member State in which its home port is situated or, failing that, of the Member State in which the owner is established.  Such authorities may, where appropriate, request the competent authorities of another Member State to issue the certificate.  Each Member State shall draw up a list indicating which of its authorities are competent for issuing the certificates and shall notify it to the Commission and the other Member States.  Any Member State which, by virtue of Article 7 (4), has not appointed a competent authority may request another Member State or States to direct their competent authorities to issue Community certificates in respect of vessels registered in or having their home port in its territory, or owned by persons established therein.    Article 10 The technical inspection referred to in Article 8 shall be carried out by competent authorities which may refrain from subjecting the vessel in whole or in part to technical inspection where it is evident from a valid attestation, issued by a classification society approved by the State in which the certificate is issued, that the vessel satisfies in whole or in part the technical requirements of Annex II.  Each Member State shall draw up a list indicating which of its authorities are competent for carrying out technical inspections and shall notify it to the Commission and the other Member States.    Article 11 The period of validity of the Community certificate shall be determined in each specific case by the authority competent for issuing such certificates. However, this period shall not exceed 10 years.    Article 12 Each Member State shall lay down the conditions under which a valid certificate which has been lost or damaged may be replaced.     TITLE III Conditions and rules for the renewal or amendment of certificates   Article 13 The Community certificate shall be renewed on expiry of its period of validity, in accordance with the conditions and rules for the issue of such certificates.    Article 14 The validity of the certificate may exceptionally be extended for a maximum period of 12 months by the authority which issued or renewed it.  Such extension shall be indicated on the Community certificate.    Article 15 In the event of major alterations or repairs which modify the structural soundness or characteristics of the vessel, the latter shall again undergo, prior to any further voyage, the technical inspection provided for in Article 8.  Following this inspection, a new certificate stating the technical characteristics of the vessel shall be issued.  If this certificate is issued in a Member State other than that which issued or renewed the initial certificate, the competent authority which issued or renewed the certificate shall be informed accordingly within one month.    TITLE IV Refusal or withdrawal   Article 16 Any decision to refuse to issue or renew the Community certificate shall state the grounds on which it is based. The person concerned shall be notified thereof and of the appeal procedure and its time limits in the Member State concerned.  Any valid certificate may be withdrawn by the competent authority which issued or renewed it if the vessel ceases to comply with the technical requirements specified in its certificate.    TITLE V Verification   Article 17 1. The competent authorities of a Member State may at any time check that a vessel is carrying a certificate valid under the terms of this Directive and satisfies the requirements set out in such certificate s).  2. If the authorities find upon inspection that the certificate is invalid, or that the vessel does not satisfy the requirements set out in the certificate, but that such invalidity or failure to satisfy the requirements does not constitute a manifest danger, the owner of the vessel or his representative shall take all necessary measures to remedy the situation. The authority which issued the certificate or which last renewed it shall be informed.  3. If, upon making the inspection referred to in paragraph 1, the authorities find that the certificate is not being carried or that the vessel constitutes a manifest danger, they may prevent the vessel from proceeding until the necessary steps have been taken to remedy the situation.  They may also prescribe measures which will enable the vessel to proceed safely, where appropriate on termination of its transport operations, to a place where it will be either inspected or repaired. The authority which issued or last renewed the certificate shall be informed.  4. A Member State which has prevented a vessel from proceeding, or has notified the owner of its intention to do so if the defects found are not corrected, shall inform the authority in the Member State which issued or last renewed the certificate, of the decision which it has taken or intends to take.  5. Any decision to interrupt the passage of a vessel taken pursuant to measures adopted in implementation of this Directive shall state in detail the reasons on which it is based. It shall be notified to the party concerned, who shall at the same time be informed of the appeal procedures available to him under the laws in force in the Member States and of their time limits.    TITLE VI Provisions applicable to the vessels of third countries   Article 18 Pending the conclusion of agreements on the mutual recognition of navigability certificates between the Community and third countries, Member States may recognize the navigability certificates of vessels from third countries and, where appropriate, issue Community certificates or supplementary Community certificates to vessels from third countries in accordance with this Directive.    TITLE VII Adaption of the Annexes to the Directive to technical progress   Article 19 The Council, acting by a qualified majority on a proposal from the Commission, shall adopt any amendments necessary to adapt the Annexes to this Directive to technical progress.     TITLE VIII Final provisions   Article 20 Directive 76/135/EEC shall continue to apply to:    - vessels in service referred to in Article 8 (2) of this Directive until such time as they undergo the inspection provided for in that Article,       - passenger vessels,       - vessels which carry a Community certificate but do not yet comply with the requirements of Annex II, in accordance with the rules set out in 13.01 (a) of Chapter 13.           Article 21 The provisions concerning the composition and qualifications of crews and the necessary certificates which apply in Member States are not affected by this Directive.    Article 22 Member States shall, after consulting the Commission, adopt the provisions necessary to comply with this Directive not later than 1 January 1985.

CHAPTER 2 REQUIREMENTS RELATING TO SHIPBUILDING     2.01. Basic rule  Vessels must be constructed in accordance with good shipbuilding practice ; their stability must accord with the use for which they are intended.       2.02. Hull      2.02.1. The hull must be sufficiently strong for all stresses to which it is subjected under normal conditions.           2.02.2. Water intakes and outlets and pipes connected to them are considered watertight if they are made in such a way that any unintentional ingress of water into the vessel is impossible.           2.02.3. Water bulkheads extending to the deck or, in the absence of a deck, to the upper edge of the hull planking or plating must be installed as follows:        (a) a collision bulkhead at an appropriate distance from the stem;               (b) in vessels whose length overall is over 25 m, a stern bulkhead at an appropriate distance from the stern.                          2.02.4. The accommodation, engine and boiler rooms and any working spaces forming part of them must be separated from the holds in a watertight manner.           2.02.5. Any compartment not normally hermetically sealed during a voyage shall be capable of being pumped dry. It must be possible to pump out each compartment separately.           2.02.6. There must be no accommodation forward of the collision bulkhead. Accommodation must be separated from the engine and boiler rooms by gas-tight bulkheads and directly accessible from the deck. Where there is no such access, there shall be an emergency exit leading directly on to the deck.           2.02.7. There must be no openings in the bulkheads and other partitions between spaces required under 2.02.3 and 2.02.4. Manholes are permitted, however, in bulkheads other than the collision bulkhead, on condition that they are bolted in a watertight manner. Hatchways in the stern bulkhead and openings for propeller shafts, piping, etc., are permitted when they are constructed in such a manner as not to affect the effectiveness of the bulkheads and other partitions between spaces.           2.02.8. By way of derogation from 2.02.5 and 2.02.7, the stern compartment may communicate with an engine room by means of a readily accessible self-closing drain installation.                  2.03. Heating, cooking and refrigeration appliances      2.03.1. The heating, cooking and refrigeration equipment, together with its accessories, must be so designed and installed that it is not dangerous even in the event of overheating. It shall be so installed that it cannot overturn or be moved accidentally.           2.03.2. When the equipment referred to in 2.03.1 uses liquid fuel it may be operated only with fuels whose flashpoint is above 55 °C.           2.03.3. By way of derogation from 2.03.2, cooking appliances and heating and refrigeration appliances fitted with burners with wicks and working on commercial paraffin may be permitted in the accommodation and wheelhouse, subject to the capacity of the fuel tank not exceeding 12 litres.            2.03.4. The installations referred to in 2.03.1 may not be installed in spaces or engine rooms in which category K1n or K1s or K2 substances Class IIIa of the ADNR are stored or used.  No flues from these installations may pass through the said spaces or engine rooms.           2.03.5. The intake of air necessary for combustion must be ensured. No closing devices should be fitted on ventilation fans.           2.03.6. Heating and cooking appliance must be securely connected to the flues. The flue pipes must be in good condition and fitted with suitable caps or devices affording protection from the wind. The flues of heating installations must be arranged in such a manner as to limit the possibility of obstruction by combustion products and to permit cleaning.           2.03.7. Vents must be fitted above the outlets of refrigeration appliances working on liquid fuel.                  2.04. Heating with liquid fuels having a flash-point above 55 °C      2.04.1. All appliances must be so built that they can be lighted without the aid of another combustible liquid. They must be fixed over a metal drip pan with sufficient capacity to prevent an accidental overflow of fuel and equipped with a device to prevent leaks in the event of the flame accidentally going out. Where the fuel tank and the appliance are separate, the drop between the tank and the burner feed may not exceed that laid down in the manufacturer's operating instructions. The tank must not be close to a flame. It must be possible to interrupt the flow of fuel from the deck.  Fuel tanks with a capacity of over 12 litres must not be installed inside accomodation.           2.04.2. When an appliance is installed in an engine room, the conditions governing its installation must be posted.  Where appliances with a naked flame are installed in an engine room, they must be placed above a leak-proof pan with side walls extending not less than 0 720 m above the floor.           2.04.3. Where an appliance is installed in the engine room, the air supply to the appliance and to the engines must be such that the appliance and the engines can function independently, effectively and in complete safety. If necessary, separate air supply pipes must be installed.           2.04.4. All natural draught equipment must be fitted with a device to prevent draught inversion.  Forced-draught equipment must be fitted with a device that automatically stops the flow of fuel when the supply of air necessary for combustion is interrupted.           2.04.5. Forced-draught central heating appliances mounted in an engine room or a compartment accessible from the engine room must also meet the following requirements:        (a) during start-up, the fan must initially function alone to ensure that the boiler is well ventilated;               (b) there must be a thermostatic device to regulate the fuel flow;               (c) the fuel must be ignited automatically by pilot flame or any other means;               (d) it must be possible to stop the fan and the burner fuel pump from the deck;               (e) if the central heating appliance is in the engine room, it must be so installed that no flame from the burner can reach other items in the space;               (f) where warm-air heating appliances are installed in the engine room, the air intakes must be connected to ducts leading to the open air.                                 2.05. Solid fuel heating      2.05.1. Except where the heating equipment is installed in a compartment constructed of fire-resistant materials and specifically designed to house a boiler, solid fuel heating appliances must be placed  on a metal plate (with raised edges), or similar protective device, to ensure that no burning fuel or hot cinders fall outside this plate.           2.05.2. Solid fuel heating boilers must be fitted with thermostatic controls to regulate the flow of combustion air.           2.05.3. A means by which cinders can be quickly doused must be placed in the vicinity of each heating appliance.                  2.06. Engine and boiler rooms and bunkers      2.06.1. Engine and boiler rooms must be so arranged that it is easy and safe to control and maintain the installations in them.           2.06.2. Liquid fuel or lubricating oil bunkers may not have common walls with the accommodation.           2.06.3. The walls, ceilings and doors of engine and boiler rooms and bunkers must be of steel or equally fire-resistant material.           2.06.4. Engine and boiler rooms and other areas in which inflammable or toxic gases may be evolved must be adequately ventilated.           2.06.5. Companionways and ladders providing access to engine and boiler rooms and bunkers must be permanently affixed and made of steel or another equally strong and fire-resistant material.           2.06.6. Engine and boiler rooms must have two exits, one of which may be an emergency exit.           2.06.7. The maximum permissible sound pressure level in the engine room is 110 dB(A). Measuring points must be chosen having regard to the maintenance necessary when the installation is operating normally.  If the sound pressure level in the engine room exceeds 90 dB(A), an explicit warning notice must be posted at each of the entrances.                    CHAPTER 3 STEERING GEAR AND WHEELHOUSE     3.01. General      3.01.1. Every vessel must be equipped with reliable steering-gear - including where necessary, a bow rudder - which ensures good manoeuvrability, having regard to the use and principal dimensions of the vessel.           3.01.2. The steering gear must be so designed that the rudder cannot change position when not intended to do so.                  3.02. Effectiveness of the steering gear  The steering gear must comply with the following requirements as to performance:      (a) where the steering gear is manually operated, one complete turn of the hand wheel must correspond to at least 3° of rudder angle;           (b) where the steering gear is fully powered, it must be possible to obtain an average rate of 4° of rudder deflection per second through the entire rudder arc when the rudder is fully immersed and with the vessel at full speed;           (c) where the steering gear is provided with power assistance gear (power assistance gear supplementing a manual main steering gear) it must be possible to achieve an average rate of 3° per second of rudder deflection through the arc 30° on either side of the neutral position of the rudder when it is fully immersed and with the vessel at full speed.           (d) where fully powered steering gear is provided with a second, manually operated control, the latter must at least permit the vessel to proceed to a mooring at reduced speed.                   3.03. General design requirements      3.03.1. The entire steering gear must be designed, constructed and installed so as to allow for permanent transverse lists of up to 15° and ambient temperatures of up to 40 °C.           3.03.2. The parts comprising the steering gear must be so dimensioned as to withstand all the maximum stresses to which they will be subject in normal operating conditions. In order to be able to resist exceptional outside forces as effectively as possible, the steering gear must not be the weakest part of the system. Any steering gear constructed in accordance with the rules of a recognized classification society may be considered satisfactory in this respect.                  3.04. Powered steering gear      3.04.1. Where a vessel is equipped with powered steering gear, an independent secondary steering system must be provided in order to ensure manoeuvrability without delay if the main gear breaks down.           3.04.2. Powered steering gear must be fitted with an overload protection device to limit the torque exerted by the drive.           3.04.3. Accidental cutting-out or failure of the powered steering gear must be indicated by visual and audible signals at the steering station.                  3.05. Engagement of the secondary drive      3.05.1. If the secondary drive of the steering gear does not engage automatically on failure of the main drive, it must be possible to engage it by hand immediately and simply with the rudder in any position. The number of manipulations to be carried out must not exceed two, and they must be capable of being performed by one person.           3.05.2. It must be possible to complete engagement in less than five seconds. It must be possible to establish from the steering station which drive installation is in use.                  3.06. Manual drive      3.06.1. If the independent secondary drive is manual it must be engaged automatically or be capable of being engaged immediately from the steering station in the event of the powered drive cutting out or failing. Claw clutches are permitted only where they are not subject to torque during engagement.           3.06.2. The power drive must not actuate the hand wheel ; there shall be a device to prevent the return of the hand wheel for any rudder position when the manual drive is engaged automatically.                  3.07. Manually operated hydraulic drive      3.07.1. Manually operated hydraulic steering gear is an installation in which the rudder is driven by a pump which in its turn is driven solely by a manually operated steering wheel (steering wheel pump).           3.07.2. Where the sole steering installation is a manually operated hydraulic system it is not to be regarded as powered steering gear in the sense of 3.04, requiring an independent secondary steering system, provided that:        - the dimensioning, construction and layout of the piping precludes deterioration through mechanical action or fire, and               - the construction of the steering wheel pump guarantees faultless operating.                                 3.08. Hydraulic drive      3.08.1. Where the main steering gear is hydraulically operated while the secondary steering is a manually operated hydraulic system, the piping of the manually operated system must be separate from that of the main installation.  It must be possible to operate the main installation without using the steering wheel pump of the secondary installation.           3.08.2. Where both the main and secondary drives are hydraulic, the respective pumps must be driven independently (e.g.:   - where the main pump is powered by the main engine, the secondary pump must be electrically driven,  - where the main pump operates on the main electric circuit, the secondary pump must operate on the emergency electric circuit,               - where the main pump is driven by No I generator, the secondary pump must be driven by No II generator).                          3.08.3. Where the secondary pump is driven by an emergency engine which does not operate continuously while the vessel is in motion, a buffer device must be installed to drive the pump whilst the emergency engine is run up.           3.08.4. The two installations must have separate pipes, valves, controls, etc. Nevertheless, where the independent functioning of the two installations is ensured, they may have common components.                  3.09. Electric drive      3.09.1. Where both the main and secondary installations are electrically powered, the respective feed and control systems must be independent of each other. Each installation must have its own motor.           3.09.2. Where the secondary motor is fed by an auxiliary engine which does not run continuously whilst the vessel is in motion, a buffer device must be installed to drive the secondary motor while the auxiliary engine is run up.                  3.10. Rudder propellers and Voith-Schneider equipment  Where remote control of rudder and Voith-Schneider propellers is electrical, hydraulic or pneumatic there must be two independent control systems between the steering station and the propulsion installation.  Where there are two or more independent propulsion installations, no secondary independent control system is required as long as the vessel remains sufficiently manoeuvrable in the event of one of the installations failing.       3.11. Remote-control installations  Remote-control installations, including those outside the wheelhouse, must be permanently affixed. Where such installations can be switched off, indicators must be provided to show whether the equipment is "on" or "off".  The arrangement and actuation of the controls must be consonant with their function.       3.12. Rudder position indicator  The position of the rudder must be clearly perceivable from the steering station ; if necessary a reliable indicator must be provided.       3.13. Steering assistance      3.13.1. Steering assistance installations are power-assistance installations fitted in addition to manually operated steering gear.           3.13.2. Where auxiliary steering gear is used, the connections between the principal and auxiliary steering gear should be such that a considerable increase in the manual force applied to the steering wheel is not necessary.           3.13.3. In addition to the foregoing, steering assistance gear must meet the following requirements:        (a) steering assistance gear must be capable of being engaged or disengaged at the steering station with the rudder in any position. The "on" and "off" positions must be clearly indicated;               (b) electrical, hydraulic and pneumatic connections between the assistance gear and the manually operated mechanical main steering gear must not compromise the capacity of the main gear to be put into operation immediately. Other failures of steering assistance gear must not cause the main system to fail or jam;               (c) all components of existing steering assistance gear and any new components incorporated later must meet the requirements for steering gear set out in this Chapter.                           3.13.4. The rudder position indicator must function both for the main and the secondary steering gear.           3.13.5. The requirements set out herein also apply when steering assistance gear is installed after the building of the vessel.                  3.14. Unobstructed view  The view in all directions from the steering station must be sufficiently unobstructed. In the forward direction it must be ensured by reliable optical means.       3.15. Sound pressure  Under normal operating conditions, the sound pressure level of the noise made by the vessel must not exceed 70 dB(A) at the helmsman's head position.       3.16. Electrical components of steering gear      3.16.1. The nominal rating of the motors must correspond to the maximum torque of the steering gear. In the case of hydraulic installations, the nominal rating of the drive motor must be such as to ensure maximum output from the pump at maximum pressure in the installation (safety valve setting) having regard to the efficiency of the pump.           3.16.2. Motors must meet at least the following requirements:        (a) Powered steering gear for intermittent operation:          - Motors of electro-hydraulic drives and associated converters must be designed for continuous duty with intermittent loading and a 15 % duty factor. A 10-minute duty cycle is to be assumed.                   - Motors for electrically powered steering gear must be designed for intermittent operation without being affected by the start-up process and with a 15 % duty factor. A 10-minute duty cycle is to be assumed.                                  (b) Steering gear with continuous power demand must be designed for continuous operation.                          3.16.3. The drive circuits and control circuits may be protected only against short circuits. The control circuits must be protected against twice the maximum rated current of the electric circuit ; the rating of the protective devices must be not less than 6 A.           3.16.4. The motor supply cables must be protected as follows:  Where fuses are used, their rated current must be two steps higher than the rated current of the motors, but not more than 160 % of the rated current in the case of motors for intermittent or short-period operation. The short-circuit instantaneous trip of circuit-breakers must not be set for a rated current exceeding 10 times the rated current of the drive motor.           3.16.5. Where there are thermal trip switches in the circuit-breakers they must either be rendered inoperative or set to twice the rated current of the motor.           3.16.6. For the electric equipment the following monitoring and indicating devices must be provided:        (a) a green pilot light indicating that the installation is functioning;               (b) a red pilot light which comes on when the installation breaks down or is accidentally disconnected, when the electric motor is overloaded or when one phase of a three-phase supply fails. An acoustic signal must sound at the same time as the red light comes on.                 Where supply is exclusively via circuit-breakers, phase failure monitoring is not required.           3.16.7. Where the rudder position indicator is electrical it must have an independent current supply.                   3.17. Lowerable wheelhouse  Where the wheelhouse can be lowered, there must be a device to prevent persons from approaching it during owering. Where persons might pass below such a wheelhouse, there must be an audible alarm which sounds automatically when the wheelhouse is lowered. In the event of failure of the device for lowering the wheelhouse, it must be possible to carry out this operation by other means.         CHAPTER 4 SAFETY DISTANCE, FREEBOARD AND DRAUGHT SCALES     4.01. Definitions  In this Chapter:      (a) "length L" means the maximum length of the hull excluding rudder and bowsprit;           (b) "amidships" means half way along the length L;           (c) a device or structural unit is deemed "sprayproof and weathertight" if in normal conditions it allows only a very small quantity of water to penetrate.                  4.02. Safety distance  The minimum safety distance shall be:      (a) for doors and openings, other than hatches, which can be closed in a sprayproof and weathertight manner : 0 715 m;           (b) for doors and openings, other than hatches, which cannot be closed in a sprayproof and weathertight manner : 0 720 m;           (c) for hatches which can be closed in a sprayproof and weathertight manner : 0 730 m;           (d) for hatches which cannot be closed by special devices, or are not closed (open holds) : 0 750 m.                  4.03. Freeboard  There must be sufficient freeboard to ensure compliance with the safety distances ; it may not be negative.       4.04. Draught marks      4.04.1. The maximum draught level must be so determined as to ensure compliance with the requirements as to the minimum safety distance at the same time, whilst ensuring that this level cannot at any point be higher than the side decks, or, in the absence of side decks, the upper edge of the hull planking or plating.           4.04.2. The maximum draught level must be indicated by clearly visible indelible draught marks.           4.04.3. The draught marks must consist of a rectangle 0 730 m long by 0 704 m high with its base horizontal and coinciding with the maximum draught level authorized in this Annex. These marks may be combined with others required under other regulations.           4.04.4. Every vessel must have at least three pairs of draught marks, one pair amidships and the others approximately one-sixth of the vessel's length from bow and stern respectively.  However:        - in the case of vessels under 40 m in length, two pairs of marks about one-quarter of the vessel's length from bow and stern respectively suffice,               - in the case of vessels not intended for the carriage of goods, one pair of marks roughly amidships suffice.                           4.04.5. Marks or information which cease to be valid as a result of a fresh survey must be removed or marked as no longer valid, under the supervision of the certificating authority.  Where for any reason a draught mark disappears, it may be replaced only under the supervision of the certificating authority.           4.04.6. Where a vessel has been measured in accordance with the Convention on the measurement of inland waterway vessels (1) and the plane of the measurement plates meets the requirements of this Annex, the measurement plates may be accepted as an alternative to draught marks.                  4.05. Draught scales      4.05.1. Any vessel whose draught may attain 1 m must bear draught scales on each side towards the stern ; it may bear additional draught scales.           4.05.2. The zero point of each draught scale must lie vertically below the draught scale in a place, parallel to the plane of maximum draught, passing through the lowest point of the hull or of the keel, if any. The vertical distance above zero must be graduated in decimetres. From the light draught plane up to 10 cm above the plane of maximum draught level these graduations must be marked by lines punched in or engraved and painted in two alternating colours in such a way as to be clearly visible. The graduation shall be marked by figures down the side of the scale at least every 5 dm and at the top of the scale.           4.05.3. The two rear measurement scales affixed pursuant to the Convention referred to in 4.04.6 may take the place of draught scales, provided that they are graduated in accordance with the above requirements and, where necessary, figures indicating the draught are added.                    CHAPTER 5 MACHINERY     5.01. General      5.01.1.

All electrical installations must be designed, constructed and installed to withstand a permanent transverse list of up to 15° and ambient temperatures of up to 40 °C.                  6.02. Maximum permissible voltages      6.02.1. The following voltages must not be exceeded: >PIC FILE= "T0033736">            6.02.2. Subject to compliance with the prescribed safety measures, higher voltages are permissible:        (a) in installations for battery re-charging equipment, as the charging process requires;               (b) for machinery whose capacity so requires;               (c) for special shipboard installations (e.g. radio installations and ignition equipment).                                 6.03. Shore connections      6.03.1. Where an electrical installation is fed by an on-shore source of current, the cables must have a fixed connection on board or be equipped with permanent connection or with current take-off devices.  Care must be taken to ensure that cables and their connections are not subject to tensible load.            6.03.2. Only flexible cable insulated by oil-resistant and flame-retardant sheathing shall be used.           6.03.3. If the lead-in voltage exceeds 50 V, the hull must be effectively earthed. The plug-in socket on the hull must bear special markings.           6.03.4. The main switchboard must include an indicator showing whether the connection to the shore network is carrying current.                  6.04. Generators and motors      6.04.1. Generators and motors must be so placed as to be readily accessible for inspection, measurements and repairs and as to prevent water and/or oil from reaching the windings. Terminal boxes must be readily accessible.           6.04.2. Generators driven by the main engine, propeller shaft or auxiliary set intended for another function must be designed for variations in the number of revolutions which may occur in service.                  6.05. Accumulators      6.05.1. Accumulators must be of a design specially adapted for use on board a vessel. Cell boxes must be made of a shock-resistant material that does not easily catch fire and be so made as to prevent any spillage of electrolyte when inclined 40° from the vertical.           6.05.2. Accumulators must be secured so as not to shift with movements of the vessel. They must not be so placed as to be exposed to excessive heat, extreme cold, spray, steam or vapour.  They must be arranged so as to be readily accessible and so as to ensure that any vapours they give off cannot harm neighbouring applicances.  Accumulator batteries may not be installed in the wheelhouse or in accommodation or holds.  Accumulators for portable appliances, however, may be placed in wheelhouses and living quarters.           6.05.3. Batteries requiring a power of more than 2 kW for charging (calculated from the maximum charging current and the nominal voltage of the battery) must be installed in a room specifically set aside for them. If placed on deck, they must be enclosed in a cabinet or chest.  Batteries requiring a power not exceeding 2 kW for charging may be installed below deck in a cupboard or chest. They may also be installed in the engine room or some other well-ventilated place provided they are protected against falling objects and dripping water.           6.05.4. The interiors of all spaces, cabinets, chests, shelving and other structural sub-assemblies specifically set aside for batteries must be protected against aggressive action of electrolyte by a coat of paint or a lining made of a material resistant to electrolyte.           6.05.5. Effective ventilation must be provided when batteries are installed in a closed compartment, cupboard or chest. The air must enter at the bottom and be discharged at the top so that total evacuation of the gas is ensured. Ventilation ducts must not include devices capable of obstructing the air flow (e.g. shut-off valve).           6.05.6. The required air flow in litres per hour shall be calculated by the following formula:  Q = 110.j.n  where:        - j represents (in amperes) one-quarter of the maximum current admissible by the charging device,               - n represents the number of cells.                          6.05.7. With natural ventilation, the cross-sectional area of the ducts must be appropriate to the air flow required at velocity of 0 75 m/sec. It must be not less than 80 cm2 for lead-plate batteries and not less than 120 cm2 for alkaline batteries.           6.05.8. Where the required ventilation cannot be obtained by natural air flow, a fan must be provided, preferably having an exhausted with its motor clear of the stream of gas of air.  Special devices must be provided to prevent gases from entering the motor.   Fans must be of a design and material precluding the production of sparks through contact between a blade and the fan casing and preventing electrostatic charges.           6.05.9. The "no smoking" symbol, with a diameter of at least 0 710 m, shall be posted on doors or covers of compartments, cabinets or chests containing batteries.                  6.06. Electrical switchboards      6.06.1. Switchboards must be situated in accessible and well-ventilated places free from gaseous or acid emissions. They must be so arranged as to be protected against jolting and against any untoward incident caused by inclement weather, water, oil, liquid fuels, steam or vapour.  Switchboards must not be placed near sounding pipes or near the vents of liquid-fuel tanks.           6.06.2. In general, materials used in the construction of switchboards must have suitable mechanical strength and be durable and non-inflammable. They must not be hygroscopic.           6.06.3. When the voltage exceeds 50 V:        (a) switchboards whose current-carrying components are so arranged or protected as to prevent accidental contact must be used;               (b) an insulating mat or an impregnated wooden grating must be provided ; this shall not apply, however, to disconnecting-switch panels;               (c) metal parts of control-panel frames or substructures and metal casings of appliances must be carefully earthed.                          6.06.4.

Indicator plates for all main or connected circuits, indicating the circuit concerned, must be affixed to switchboards.                  6.07. Switches, plugs, fuses and cable protection      6.07.1. The whole installation, branch cables from the main switchboard and branch cables from the distribution panel, must be capable of being disconnected by means of switches or automatic circuit-breakers which simultaneously switch off all conductors carrying current.  Where the current is as 50 V or less, exceptions are permitted for branch cables from distribution panels, particularly in the case of circuits with individual switches for each appliance.           6.07.2. All generators and circuits must be protected against excess current in any unearthed pole or conductor. Automatic circuit-breakers with short-circuit and surge trips, or safety fuses of the sealed type, may be used for this purpose. Such electrical protection devices must be so installed as to be adequately protected against jolting.           6.07.3. The requirements of 3.16.3, 3.16.4 and 3.16.5 must be met as regards the protection of components of the steering gear.           6.07.4. The "on" and "off" positions must be indicated on the cut-off devices. This does not apply to light switches handling less than 10 A.           6.07.5. All switches and plugs must be designed to disconnect all conductors simultaneously. Light switches handling less than 10 A may be exempted except in the case of the lighting of damp areas.           6.07.6. Appliances requiring a current of more than 10 A must be connected to a special circuit.           6.07.7. Cables must have a watertight sheath which is flame-retardant and of a type normally used on ships.  Other types of cable may be used in the living quarters on condition that they are effectively protected and flame retardant.  Cables must be protected against all risks of damage in normal service conditions, particularly on deck and in the holds.            6.07.8. Moveable appliances may under no circumstances be fed by metal-sheathed cables.           6.07.9. Cables and equipment must be connected by means of sturdy and durable devices which prevent the connections from coming under tensile load.            6.08.

All lighting appliances shall be so installed that the heat they emit cannot set fire to nearby inflammable objects or units.           6.09.2. In enclosed spaces in which accumulators are installed or paints and other highly inflammable substances are stored, only lighting appliances presenting a limited risk of explosion shall be used.           6.09.3. Lighting appliances in engine and boiler rooms must be distributed between at least two circuits.                  6.10. Signal lights      6.10.1. The light-control switchboard must be installed in the wheelhouse ; it must be capable of being fed by a separate cable from the main switchboard.           6.10.2. Each light must be supplied separately from the light-control switchboard and separately protected and controlled. Lights forming a group may be supplied by a single circuit on condition that the failure of any light activates the alarm in the monitoring equipment.           6.10.3. Unless direct monitoring from the wheelhouse is possible, the lights must be monitored by means of tell-tale lights, or similar devices, fitted on the control panel in the wheelhouse. A fault in the tell-tale light must not affect the operation of the light which it monitors.                  6.11. Earthing      6.11.1. Metal parts not current-carrying when in use, such as machine frames and casings, appliances, fittings and accessories, must be earthed if they are not already so mounted as to be in effective metallic contact with the hull.           6.11.2. In direct current operation, metal fittings and accessories, metal sheaths of cables and ducts must be earthed at both ends at least. Where cables are mounted on wood or a plastic substance, one earth connection will suffice. In alternating current operation, single-conductor cables and ducts may not be earthed at more than one point.           6.11.3. In installations where the voltage does not exceed 50 V, earthing may be dispensed with.           6.11.4. Where the voltage exceeds 50 V, the casings of mobile current-consuming appliances, if not made of an insulating material or not protected, must be earthed through the feeder cable by means of an additional conductor not normally carrying current.                  6.12. Emergency power installation      6.12.1. The following are permitted as emergency power installations:        (a) an auxiliary set with a fuel supply system independent of the main engine and a separate cooling system, which in the event of failure of the main circuit starts automatically or can be hand-started if it is installed in the immediate vicinity of the wheelhouse or any other station continuously manned by qualified personnel, and is capable on its own of covering current supply requirements within 30 seconds ; or               (b) an accumulator battery which automatically takes over the supply of current in the event of failure of the main circuit, or can be switched on manually from the wheelhouse or any other station continuously manned by qualified personnel, and is capable of supplying the listed current-consuming devices for the duration of the prescribed period without being recharged and without an inadmissible drop in voltage.                           6.12.2. Auxiliary sets, emergency batteries and the associated switch gear may be installed in the engine room but in this case as high as possible.           6.12.3.

Liquefied gas installations must be suitable throughout for use with propane, must be installed in accordance with good practice and conform to the current regulations of the Member State which issued the certificate.           8.02.2. A liquefied gas installation may be used only for domestic purposes in the accommodation and the wheelhouse.           8.02.3. There may be a number of separate installations on board. A single installation may not be used to serve accommodation areas separated by a hold or a fixed tank.                  8.03. Receptacles      8.03.1. Only receptacles with approved capacities of between 5 and 35 kg are permitted.           8.03.2. The receptacles must satisfy the requirements in force in the Member State which issued the certificate.  They must bear the official stamp certifying that they have passed the statutory tests.                  8.04. Siting and arrangement of supply unit      8.04.1. Where receptacles with a load of up to 35 kg are used, the supply unit must be installed on deck in a special cupboard or wall cupboard located outside the accommodation area in a position such that it does not interfere with movement on board. It must not, however, be installed against the fore or aft bulwark plating. The cupboard may be a wall cupboard set into the superstructure provided that it can only be opened outwards. It must be so located that the pipes leading to the gas consumption points are as short as possible.  Each installation may comprise up to four receptacles in operation simultaneously, with or without the use of an automatic reversing coupler. The number of receptacles on board, including spare receptacles, must not exceed six per installation.  The pressure reducer or in the case of two-stage reduction the first pressure reducer, must be fitted to a bulkhead on the same cupboard as the receptacles.           8.04.2. The supply unit must be so installed that any leaking gas may be evacuated from the cupboard containing the unit without any risk that it may penetrate inside the vessel or come into contact with anything that might set it on fire.           8.04.3. The cupboard must be constructed of fire-resistant materials and must be adequately ventilated by apertures in the top and bottom. The receptacles must be placed upright in the cupboard in such a way that they cannot be overturned.           8.04.4. The cupboard must be so designed and placed that the temperature of the receptacles cannot exceed 50 °C;           8.04.5. The inscription "liquefied gas installation" and the "no smoking" symbol as described in 6.05.9 must be affixed to the outer wall of the cupboard.           8.04.6. If interior lighting is needed in the cupboard, it must be electrical and the installation must be flame-proof.                  8.05. Spare and empty receptacles  Spare and empty receptacles which are not kept in the supply unit must be stored outside the accommodation area and the wheelhouse in a cupboard designed according to the requirements of 8.04 of this Chapter.       8.06. Reducing valves      8.06.1. The gas consuming applicances may be connected to the receptacles only through a distribution system fitted with one or more reducing valves to bring the gas pressure down to the utilization pressure. The pressure may be reduced in one or two stages. All reducing valves must be set permanently at a pressure determined in accordance with 8.07 below.           8.06.2. The final pressure reducers must either be fitted with or immediately followed by a device to protect the pipe automatically against excess pressure in the event of a malfunctioning of the reducing valve. Any gas which this protection device allows to escape must be evacuated into the  open air without any risk that it may penetrate inside the vessel or come into contact with anything that might set it on fire ; if necessary, a special pipe must be fitted for this purpose.           8.06.3. Both the protection devices and the vents must be protected against the entry of water.                  8.07. Pressures      8.07.1. The pressure at the outlet from the last pressure reducer must be more than 0 705 bar above atmospheric pressure, with a tolerance of 10 %.           8.07.2. Where two-stage reducing systems are used, the mean pressure must not be more than 2 75 bar above atmospheric pressure.                  8.08. Pipes and flexible tubes      8.08.1. Pipes must consist of fixed steel or copper tubing.  Pipes connecting with the receptacles, however, must be high-pressure flexible tubes or spiral tubes suitable for propane. The gas-consuming appliances may, if not installed in a fixed manner, be connected by means of suitable flexible tubes not more than 1 m in length.           8.08.2. Pipes must be able to withstand any stresses or corrosive action which may occur under normal operating conditions on board, and their characteristics and layout must be such that they ensure a satisfactory flow of gas at the appropriate pressure to the gas-consuming appliances.           8.08.3. Pipes must have as few joints as possible. Both pipes and joints must be gas-tight and must remain gas-tight despite any vibration or expansion to which they may be subjected.           8.08.4. The pipes must be readily accessible, properly fixed and protected at every point where they might be subject to impact or fraction, particularly where they pass through steel bulkheads or metal partitions.  The entire outer surface of steel pipes must be treated against corrosion.           8.08.5. Flexible pipes and their joints must be able to withstand any stresses which may occur under normal operating conditions on board. They must be unencumbered and fitted in such a way that they can be inspected over their entire length.                  8.09. Distribution system      8.09.1. No part of the liquefied gas installation may be located in the engine room.  On tanker vessels subject to the rules on the carriage of dangerous goods, no part of the liquefied gas installation may be located in the cargo area.           8.09.2. A valve which is rapidly and easily accessible must provide a means whereby the entire distribution system can be shut off.           8.09.3. Each gas-consuming appliance must be supplied by a separate branch of the distribution system, and each branch must be controlled by a separate closing device.           8.09.4. The valves must as far as possible be fitted at points where they are protected from the weather and from impact.                  8.10. Gas-consuming appliances and their installations      8.10.1. The only appliances that may be installed are propane-consuming appliances approved in the Member State which issued the certificate, which are equipped with devices that effectively prevent the escape of gas, both in case of extinction of the flames and in case of extinction of the pilot light.           8.10.2. Each appliance must be so placed and connected as to avoid any risk of accidental wrenching of the connecting pipes.           8.10.3. Heating and water-heating appliances must be connected to a duct for evacuating combustion gases.            8.10.4. The installation of gas-consuming appliances in the wheelhouse is permitted only if the wheelhouse is so constructed that no gas which leaks accidentally can escape into the lower parts of the vessel, in particular through the control runs leading to the engine room.  On tanker vessels subject to the rules on the carriage of dangerous goods, no gas-consuming appliance may be located in the wheelhouse.           8.10.5. Gas-consuming appliances may be installed in sleeping quarters only if combustion takes place independently of the air in the quarters.           8.10.6. Gas-consuming appliances in which combustion depends on the air in the rooms in which they are located must be installed in rooms which are sufficiently large.           8.10.7. On tanker vessels subject to the rules on the carriage of dangerous goods, gas-consuming appliances must bear a prominent red mark.                  8.11. Ventilation and evacuation of combustion gases      8.11.1. In rooms containing gas-consuming appliances in which combustion depends on the ambient air, the supply of fresh air and the evacuation of the combustion gases must be ensured by means of ventilation apertures of adequate dimensions determined according to the capacity of the appliances.           8.11.2. The ventilation apertures must not have any dosing device and must not give on to sleeping quarters.           8.11.3. The evacuation devices must be so designed as to ensure the safe evacuation of the combustion gases. They must be reliable in operation and fire-resistant. Their operation must not be affected by the ventilators.                  8.12. Instructions for use and safety  A notice containing instructions on the use of the installation shall be affixed on board in a suitable place. The notice must bear inter alia the following instructions in the appropriate language or languages:      - "the taps of receptacles which are not connected to the distribution system must be closed, even if the recipients are presumed to be empty",           - "flexible pipes must be changed as soon as their condition so requires",           - "all receptacles must remain connected unless the corresponding connecting pipes are closed by taps or sealed".                  8.13. Inspection  Before a liquefied gas installation is used, after any modification or repair and on every renewal of the attestation referred to in 8.15, the whole of the said installation must be submitted for inspection by an approved expert of the Member State issuing the certificate. At the time of the inspection the expert must verify whether the installation conforms to the requirements of this Chapter. He must submit an inspection report to the competent authority which issues the certificate.       8.14. Tests  The tests on the installation, after mounting, must be carried out as follows:      8.14.1. Medium-pressure pipes between the outlet of the first reducing device and the valves fitted before the final pressure reducer:        (a) strength test, carried out with air, an inert gas or a liquid at a pressure 20 bar above atmospheric pressure;               (b) gas-tightness test, carried out with air or an inert gas at a pressure 3 75 bar above atmospheric pressure.                          8.14.2. Pipes at the utilization pressure between the single or final pressure reducer and the valves fitted before the gas-consuming appliances:   - leak test, carried out with air or an inert gas at a pressure of 1 bar above atmospheric pressure.           8.14.3. Pipes situated between the single or final pressure reducer and the controls of the gas-consuming appliance:   - leak test at a pressure of 0 72 bar above atmospheric pressure.            8.14.4. In the tests referred to in 8.14.1 (b), 8.14.2 and 8.14.3, the pipes are deemed gas-tight if, after sufficient time to allow for normal balancing, no fall in the test pressure is observed during the following 10 minutes.           8.14.5. Receptacle connectors, piping and other fittings subjected to the pressure in the receptacles, and joints between the reducing valve and the distribution pipe:  - leak test, carried out with a foaming substance, at the operating pressure.           8.14.6. All gas-consuming appliances must be brought into service and tested at the nominal pressure to ensure that combustion is satisfactory with the regulating knobs in the different positions.  The safety devices must be checked to ensure that they operate satisfactorily.           8.14.7. After the test referred to in 8.14.6, it must be verified, in respect of each gas-consuming appliance connected to a flue, whether, after five minutes' operation at the nominal pressure, with windows and doors closed and the ventilation devices in operation, any combustion gases are escaping through the damper.  If there is a more than momentary escape of such gases, the cause must immediately be detected and remedied. The appliance must not be approved for use until all defects have been eliminated.                  8.15. Attestation      8.15.1. The certificate must include an attestation to the effect that, following the inspection referred to in 8.13, all liquefied gas installations conform to the requirements of this Chapter.           8.15.2. The attestation shall be valid for a period not exceeding three years. It may be renewed only after a further inspection carried out in accordance with 8.13.  Where the owner of a vessel or his representative submits a reasoned request, the Member State which issued the certificate may extend the validity of the attestation for not more than six months without carrying out the inspection required under 8.13. Such extension must be entered in the certificate. The date on which the next inspection would normally have been due may not be postponed as a result of the extension.                  CHAPTER 9 SPECIAL WHEELHOUSE ARRANGEMENTS FOR STEERING ON RADAR BY ONE PERSON     9.01. General  A wheelhouse is deemed to be specially arranged for steering on radar by one person if it fulfils the conditions of this Chapter       9.02. General design conditions      9.02.1. The wheelhouse must be designed to accommodate a seated steersman.           9.02.2. All appliances, instruments and controls must be so arranged that the steersman can use them conveniently during the voyage without leaving his seat and without losing sight of the radar screen.  The controls must move easily into the operating position, which must be unmistakably clear.           9.02.3. Monitoring instruments must be easy to read and their illumination must be capable of continuous adjustment to the point of extinction, whatever the lighting conditions inside the wheelhouse, so that the illumination is not troublesome and does not impair visibility.           9.02.4. The wheelhouse must be equipped with adjustable heating. The wheelhouse darkening device must not adversely affect ventilation.                  9.03. Radar equipment and speed of rotation indicator      9.03.1. The radar screen must not be substantially off the steersman's line of vision when he is in the normal position at the wheel.            9.03.2. The radar image must remain fully visible, without the aid of a mask or screen, irrespective of the lighting conditions prevailing outside the wheelhouse.           9.03.3. A speed-of-rotation indicator must be installed directly above or below the radar screen.                  9.04. Signalling and signal-emitting equipment      9.04.1. Lights and light signals must be controlled by switches whose layout reflects the actual position of the lights and light signals. Each light or light signal must be monitored by a tell-tale light of the same colour as the light or light signal which it monitors, built into the switch or mounted beside it. Failure of a light or light signal must cause the corresponding tell-tale light to be extinguished.           9.04.2. Audible warning devices must be controlled by foot.                  9.05. Installations for steering the vessel and operating the engines      9.05.1. The steering gear of the vessel must be controlled by a horizontal lever. This lever must be easy to operate and the angle between the lever and the centreline of the vessel must accurately reflect the angle of deflection of the rudder plate. It must be possible to release the lever, whatever its position, without the position of the rudder plate changing. An equivalent control system is permitted for Voith-Schneider and steerable propellers.  If the vessel is also fitted with reversing rudders or bow rudders they must be controlled by separate levers.           9.05.2. Every engine must be controlled by a single lever moving through the arc of a circle in a vertical plane more or less parallel to the longitudinal axis of the vessel. Forward movement of the lever must cause the vessel to move ahead and its movement toward the stern must cause motion astern. The drive must be engaged or reversed when the lever is approximately in the neutral position. There must be a clearly distinguishable click as the lever goes into the neutral position. The sweep of the lever from the neutral position to the "full speed ahead" position and from the neutral position to the "full speed astern" position must not exceed 90°.           9.05.3. The direction and rare of rotation of the propellers must be indicated.                  9.06. Stern anchor handling gear  The steersman must be able to cast the stern anchor(s) without leaving his seat. This requirement shall not apply to vessels of pushed trains or breasted-up formations not exceeding 86 m in length.       9.07. Telephone equipment      9.07.1. Vessels must be fitted with a radiotelephone installation for vessel-to-vessel service. Reception must be by a loudspeaker and transmission by a fixed microphone. The steersman must be able to effect both operations. The changeover from reception to transmission must be effected by push-button. The steersman must be able to reach this installation from his seat.  The same requirements shall apply where necessary to the nautical operations service.           9.07.2. If the wheelhouse is fitted with a radiotelephone installation connected to the public service, reception must be by a loudspeaker at the steersman's seat. However, the microphone for vessel-to-vessel communication may not under any circumstances be used for calls via the public service.           9.07.3. All vessels must have a voice communication system. This shall serve at least the following points:        - the bows of the vessel or the head of the train,               - the crew's quarters, and               - the steersman's cabin.                 Reception must be by a separate loudspeaker and transmission via a fixed microphone which may be the one used for the vessel-to-vessel service on condition that this does not cause confusion between the two networks. The changeover from reception to transmission must be effected by push-buttons or change-over switches.                   9.08. Alarm signals      9.08.1. An alarm system controlled by an "off/on" switch must be available to the steersman. Switches which automatically return to the "off" position when released are not permitted.           9.08.2. The strength of this signal must be not less than 75 dB(A) in the accommodation. In the engine room it shall be 5 dB(A) in excess of the ambient noise level with the propulsion machinery at full power.                  9.09. Other instruments  Instruments other than those listed above must be reduced to a minimum.       9.10. Endorsement of the inspection certificate  If the vessel conforms to the requirements of this Chapter, the certificate must be endorsed as follows:  "Approved for steering on radar by one person."         CHAPTER 10 SPECIAL PROVISIONS FOR VESSELS DESIGNED TO BE MADE UP INTO PUSHED TRAINS, PULLED TRAINS OR TO BE BREASTED UP     10.01. Pushers      10.01.1. Pushers must have at the bow a "pusher platform", a device not less than two-thirds as wide as the greatest width of the vessel. The platform must be so designed that, from the start of the coupling manoeuvres, the personnel involved can move easily and without danger from one vessel to the other with the coupling gear.  The platform must also be such as to enable the pusher to take up a fixed position in relation to the lighters, and particularly to prevent the pusher sheering out sideways to the stern of the lighters.           10.01.2. Pushers must be equipped with the requisite coupling gear ; where cables are used for coupling, pushers must be equipped with at least two special winches or equivalent devices.           10.01.3. The main engines must be controlled from the wheelhouse. Their operation must be monitored by means of devices installed in the wheelhouse.                  10.02. Lighters      10.02.1. Chapter 3 and 7.02, 7.04 and 7.05.1 shall not apply to lighters. 5.06 shall not apply to lighters with no accommodation and no engine or boiler rooms.           10.02.2. Ship-borne lighters shall also comply with the following construction requirements:        (a) The transverse watertight bulkheads referred to in 2.02.3 are not required if the bows are capable of withstanding an impact at least 2 75 times that required in the collision bulkhead of an inland waterway vessel of the same draught built to the specifications of a classification society approved by the Member State which has to issue the certificate.               (b) By way of derogation from 2.02.5, compartments with a double bottom into which access is difficult need not be drainable unless the volume of the space concerned exceeds 5 % of the displacement of the ship-borne lighter at maximum authorized draught.               (c) The surface of decks, side decks and hatch covers must have an antislip finish. Where necessary, sloping surfaces must be fitted with raised slats.               (d) Along the line where the deck or side decks form an angle with the ship's side there must be toerails or stringer bars at least 0 703 m high and guard rails at least 0 790 m high ; the guard rails may be removable.  No guard rails are required at the bows.                                  10.03. Powered vessels and tags capable of pushing  In order to be approved for carrying out pushing operations, powered vessels and tugs must:      (a) have a pusher platform as required under 10.01.1, or           (b) be fitted with appropriate and effective devices to prevent the pusher vessel sheering out sideways to the stern of the vessel to be pushed.                  10.04. Pushed train tests      10.04.1. For the purpose of issuing a certificate for a pusher or pusher tug, or of endorsing the certificate of a powered vessel or rug with "suitable for pushing", it is for the competent authority to decide whether, and which, trains are to be submitted for tests, and to carry out tests with those formations which it regards as the most unfavourable. The certificate must show the conditions under which the pusher is certified or the endorsement "suitable for pushing" is valid.           10.04.2. The tests must prove that:        (a) the train has sufficient directional stability;               (b) a major course alteration followed immediately by a return to the original course can be made swiftly and easily;               (c) the train has sufficient speed through the water;               (d) where necessary, astern propulsive power is sufficient to enable the train to stop when headed downstream;               (e) when the train is being coupled or uncoupled, the coupling gear is easy and safe to manipulate.  The coupling gear must also meet the following requirements:        - the rigidity of the rain must be maintained,               - coupling gear must ensure uniform tension, preferably by means of special winches.                          10.04.3. In the course of the above tests, the authority competent for issuing the certificate will not take into account the effects of special devices (rudders, propulsion mechanisms, etc.) installed on lighters unless the latter always form part of the same train. Where they do, the authorized lighters must be named in the certificate of the vessel providing the propulsion for the train.                  10.05. Towing vessels  In order to be authorized to effect towing operations, vessels must meet the following requirements:      (a) towing gear must be so installed that, when in use, it does not compromise the safety of the crew or cargo. The vessel must remain sufficiently manoeuvrable and stable when towing;           (b) the steersman must be able to operate the propulsion machinery himself or be able to control such operations without leaving the steering station;           (c) where cables are used for towing, the towing gear must comprise winches or a towing hook which can be slipped from the steering station. The towing gear must be installed forward of the plane of the propellers. However, this does not apply to articulated tugs.                  10.06. Vessels designed to propel breasted-up formations  In order to be authorized to propel breasted-up formations, vessels must:      1. comply with the provisions of 10.05 (a) and (b);           2. be equipped with appliances which in number and layout ensure that the formation of powered and propelled vessels remains securely breasted-up whether laden or unladen.                     CHAPTER 11 HEALTH AND SAFETY IN THE CREW'S ACCOMMODATION AND WORKING STATIONS     11.01. General      11.01.1. Vessels on which the uninterrupted presence of persons is required out of working hours must have the necessary accommodation.           11.01.2. The accommodation must be designed, dimensioned and fitted out in such a way as to satisfy the needs of those on board as to safety, health and comfort. Such accommodation must comply with the requirements of 11.02 to 11.12.           11.01.3. The inspecting authorities may permit exceptions to the rules set out below when the safety, health and comfort of those on board are ensured in an equivalent manner by other measures.           11.01.4. 11.03, 11.08.2, 11.09, 11.10 and 11.11 do not apply to accommodation used solely by crew members who are not workers employed under an employment contract. These derogations must be mentioned under heading No 21 of the certificate.                  11.02. Siting and fitting-out of the accommodation      11.02.1. The accommodation must be situated aft of the collision bulkhead and as much as possible of the accommodation must be above deck.  In the fore section of the vessel, no floors shall be more than 1 720 m below the plane of maximum draught.  Exceptions may be authorized for accommodation which is not occupied permanently.           11.02.2. The accommodation must be accessible easily and in complete safety.  As a general rule, the accommodation and galleys must be accessible from deck by means of a corridor.           11.02.3. The accommodation must be so located and fitted out as to avoid as far as possible the penetration of polluted air from other compartments of the vessel (e.g. engine room and holds). Where forced-air ventilation is used the intake vents must be so placed as to satisfy the above requirement. Stale air from galleys or sanitary installations must be expelled from the vessel by the most direct route.           11.02.4. Accommodation must be protected from unacceptable noise and vibration. The maximum permissible sound pressure levels are:        - 70 dB(A) in the living quarters,               - 60 dB(A) in the sleeping quarters, except in the case of vessels working only by day.                          11.02.5. To permit rapid evacuation in the event of wreck or fire, the accommodation must be provided with emergency exits, distant from each other if possible, and where possible to port and starboard.  This does not apply to:        (a) accommodation with several exits, ports or skylights which would permit rapid evacuation;               (b) sanitary installations.                          11.02.6. Emergency exits and ports or skylights designed for use as emergency exits must have a clear opening of at least 0 736 m2 and the smallest dimension must be at least 0 750 m.                  11.03. Dimensions of the accommodation      11.03.1. The headroom in the crew's quarters must not be less than 2 m.           11.03.2. The free floor area of the accommodation must not be less than 2 m2 per occupant. The area occupied by movable furniture such as chairs and tables shall be included in the free floor area.            11.03.3. The volume of air per occupant must not be less than 3 75 m3 in the living quarters and not less than 5 m3 for the first occupant and 3 m3 for the second in the sleeping quarters. The volume of air is that remaining after the appropriate deductions have been made for lockers, berths, etc.           11.03.4.

CHAPTER 12 PROVISIONS RELATING TO TECHNICAL REQUIREMENTS ADDITIONAL TO ZONE 4 REQUIREMENTS APPLICABLE TO VESSELS OPERATING ON ZONE 3 INLAND WATERWAYS (The requirements of 4.02 and 4.03 do not apply to Zone 3 waterways)     12.01. Requirements relating to shipbuilding  Vessels, pushed trains and breasted-up formations with a maximum length exceeding 86 m.      12.01.1. Any vessel fitted with mechanical means of propulsion and having a maximum length exceeding 86 m must be built and fitted out in such a way as to be capable of coming to a halt pointing downstream in time, while remaining sufficiently manoeuvrable during and after stopping. This requirement also applies to pushed trains and breasted-up formations with a length exceeding 86 m.  To this end it is verified, on the basis of a stop test, whether propulsive power when going astern is sufficient. A stop test is not necessary if it can be substantiated in some other manner that this requirement is fulfilled.  The maximum permitted displacement of the vessel or train during downstream navigation is determined from the results of the stop test or substantiation ; the inspection certificate will be endorsed accordingly.           12.01.2. The vessel, pushed train or breasted-up formation must be capable of attaining an adequate minimum speed.                  12.02. Freeboard, safety distance and draught scales      12.02.1. Definitions  In this Chapter:        (a) "length L" means the maximum length of the hull, excluding rudder and bowsprit;               (b) "breadth B" means the maximum beam measured outside the side planking or plating, not including paddle wheels;               (c) "amidships" means half way along the length L;               (d) "enclosed superstructure" means a structure made up of solid watertight walls above the deck and joined to it in a permanent and watertight manner;          - "breadth of a superstructure" is its mean breadth, and                   - "height of a superstructure" is its mean vertical height, measured at the side of the vessel between the top deck of the superstructure and the freeboard deck ; if the walls have openings such as doors or windows, the height of superstructures is measured only up to the lowest point of the openings;                                  (e) structural elements and devices are deemed "watertight" when they are fitted out in such a manner as to prevent the ingress of water into the vessel, either:          - when subjected to a pressure equivalent to 1 m of water for one minute, or                   - when subjected to a jet of water with a pressure of not less than 1 bar applied for 10 minutes in all directions and on the entire surface;                                  (f) structural elements and devices are deemed "spray-proof and weathertight" if in normal conditions they allow only a very small quantity of water to penetrate.                           12.02.2. Safety distance        1. The safety distance must be not less than 30 cm.               2. On vessels whose openings cannot be closed by means of spray-proof and weathertight devices and vessels which navigate with their holds uncovered the safety distance is increased by 20 cm.  In the case of vessels with uncovered holds, however, the increase applies only to the coamings of uncovered holds and only until the prescribed distance of 50 cm is attained between the plane of greatest draught and the upper edge of the coamings.  12.02.3. Freeboard          1. The freeboard of vessels with a continuous deck, without sheer and without superstructures must be 150 mm.  This value is also the basic freeboard for vessels with sheer and superstructures.                   2. The freeboard of vessels with sheer and superstructures is calculated by the following formula: >PIC FILE= "T0033737">   where:            - le is the effective length of a superstructure (in m), and                       - L is the length of the vessel (in m) as defined in 12.02.1,                       - Se1 and Se2 are respectively the effective forward sheer and the aft sheer (in mm),                       - ß1 and ß2 are respectively correcting coefficients for the effect of the forward sheer and aft sheer resulting from the presence of superstructures at the extremities of the vessel,                       - ß1 is calculated by the following formula: >PIC FILE= "T0033738">                          where:   - ß2 is calculated by the following formula: >PIC FILE= "T0033739">   In these formulae:            - le1 is the effective length of the forward superstructures (in m), and                       - le2 is the effective length of the rear superstructures (in m).                         However, the effective length is taken into consideration only if it is located in the forward quarter or rear quarter of the length L of the vessel.                  3. The effective sheer as calculated by the following formula:  Se = p S  where:          - S is the actual sheer at the extremity in question (in mm),                   - S forward may not be taken to exceed 1 000 mm,  - S aft cannot be taken to exceed 500 mm, and            -  >PIC FILE= "T0033740">   X is the abscissa, measured from the extremity, from the point where the sheer equals 0 725 S (see sketch below). >PIC FILE= "T0033741">   Where ß2 Se2 exceed ß1 Se1, the value of ß1 Se1 is taken as the value of ß2 Se2.               4. The effective length of a superstructure is calculated by the formula: >PIC FILE= "T0033742">   where:          - l is the actual length of the superstructure in question (in m),                   - b is the breadth of the superstructure in question (in m),                   - B is the breadth of the vessel as defined in 12.02.1 (in m)  (for le1 and le2, however, the breadth of the vessel at the mid-point of the superstructure in question should be used),   - h is the height of the superstructure in question (in m)  (in the case of hatches, however, h is obtained by reducing the height of coamings by half the safety distance referred to in 12.02.2).  A value exceeding 0 76 × 0 76 m (i.e. 0 736 m) must not in any event be assigned to h. >PIC FILE= "T0033743">     12.02.4. Minimum freeboard  Taking into account the reductions referred to in 12.02.3, the minimum freeboard must not be less than 50 mm.  However, the competent authority may stipulate a smaller freeboard if it is guaranteed that the crew can move without danger over the whole length of the vessel to carry out their work.    12.02.5. Draught marks  In the case of vessels operating in the various inland waterway zones (Zones 1, 2, 3 and 4), there must be a vertical line and one or more additional draught lines of a length of 150 mm towards the bow on the draught marks fore and aft for one or more inland waterway zones.  The vertical line and the horizontal lines must be 30 mm thick. Beside the draught mark running towards the bow there must appear a figure measuring 60 × 40 mm indicating the corresponding zone (see Figures 1 and 2).                         12.03. Equipment  Lifebuoys, ball-floats and life-jackets.  Self-propelled craft up to 40 m in length must have on board at least three lifebuoys or two lifebuoys and two ball-floats.  Figure 1 >PIC FILE= "T0033744">    Figure 2 >PIC FILE= "T0033745">   12.04. Special provisions for vessels designed to be made up into pushed trains, pulled trains or to be breasted up    12.04.1. Pushers must be provided with powered anchor windlasses.       12.04.2. Vessels capable of towing  In order to perform towing operations, vessels must meet the following requirements:      (a) The length of the vessels must not exceed 86 m ; exceptionally, the locally competent authority may authorize vessels with a length exceeding 86 m to tow downstream when certain conditions to be laid down by it are satisfied.

Vessels already in service on or laid down before 1 January 1985 but whose construction and equipment do not fully comply with the provisions of this Directive must be brought into line with them within one year of the date of the first technical inspection provided for in Article 8 (2) of the Directive, with the exception of the provisions in Table 1 below, to which the following conditions apply:      (a) The requirements set out in the first column of the table must be implemented within five years of the date of the first inspection provided for in Article 8 of the Directive.           (b) The requirements in the second column do not apply to vessels already in service where the safety of vessel and crew is ensured in another appropriate manner.            (c) The derogations referred to in 13.01 (a) and 13.01 (b) do not apply to parts which have been altered or replaced.           (d) Where implementation of the requirements in 13.01, 13.01 (a) (after expiry of the transitional period) and 13.01 (c) is not practicable or would entail unreasonable outlay, the authority responsible for issuing the certificate may grant derogations.           (e) Relevant details of any derogations granted under 13.01 (a) must be entered in the certificate during the first inspection after the entry into force of this Directive ; derogations under 13.01 (d) must be entered when granted.                  13.02. Vessels already approved for radar steering by one person have five years to comply with the requirements of Chapter 9. Vessels requesting such approval for the first time must be brought into conformity with Chapter 9 before they can obtain approval.       13.03. Vessels which on 1 January 1985 have permanently installed fire-extinguishing appliances using CO2 as an extinguishing agent may retain such appliances provided that they satisfy the following conditions:  CO2 is authorized as an extinguishing agent in permanently installed appliances subject to the following conditions:      (a) CO2 appliances may be used only in engine, boiler and pump rooms.           (b) All permanently installed CO2 appliances must be fitted with an alarm whose signal is clearly audible in all areas designed to be flooded with CO2, even above the highest possible level of intrinsic noise during operation, and clearly distinguishable from all other audible warning signals on board.  CO2 alarm signals must also be clearly audible in neighbouring areas - through closed communications hatchways and above the highest possible level of intrinsic noise produced during operation - if these areas can be evacuated through the one designed to be flooded with CO2.  The following notice in red letters on a white background, in Dutch, French and German and in the language(s) of the Member States in which the vessel operates, must be displayed in an appropriate place at the entrance to and exit from any area likely to be flooded by CO2:  "Leave this area immediately when the CO2 warning signal is sounded (description of the signal) - danger of suffocation."           (c) Clearly legible and durably marked instruction for use in Dutch, French and German and in the language(s) of the Member State in which the vessel operates must be displayed near all devices for activating CO2 extinguisher systems.  Pipes terminating in areas likely to be affected by CO2 must be fitted with closing devices.  The warning device required under (b) above must be activated automatically before an extinguisher system is put into operation.           (d) CO2 tanks must be installed in a gas-tight area separated from other areas.  This area must be directly accessible from the outside only, and must have an adequate and independent ventilation system completely separate from all other ventilation systems on board.  The temperature in this area must not exceed 60 °C.  All tanks under pressure must bear the inscription "CO2" in white on a red background. The characters must be at least 6 cm high.           (e) CO2 tanks, fittings and piping under pressure must conform to the specifications in force in the Member State which issued the certificate. They must bear the official stamp certifying acceptance following the regulation rests.           (f) The alarm referred to in (b) above must be checked at least once every 12 months.   Fire-fighting systems must be checked at least once every two years. This check must at least include:        - external inspection of the entire system,               - functional testing of piping and outlet nozzles,               - functional testing of the triggering mechanism,               - a check on the CO2 supply in each service tank.                          (g) The inspection certificates signed by the inspectors must be carried on board. These certificates must mention at least the abovementioned checks, the results obtained and the date of the check.           (h) Where the vessel is equipped with one or more CO2 extinguishing systems that have been checked, the certificate issued for the vessel must be endorsed as follows under heading No 18:  "... (number) fixed CO2 extinguishing system(s). The required certificates must be carried on board."                  13.04 The provisions of Chapter 11 apply only to the vessels referred to in Article 8 (1) of the Directive. However, for reasons of safety, the provisions in 11.01.1, 11.01.3, 11.01.4 and, within the time limits stipulated, those in Table 2 of this Chapter apply also to the vessels referred to in 13.01.       13.05. On existing vessels with side decks less than 0 750 m wide, a handrail in the form of a taut cable along the waterside or handrails along hatch coamings may be substituted for the guardrail.
