were 26 ft, 31 1/2 and one 28 ft respectively. Another interesting feature of the ship was the drum-room or pay-out office located at the stern deck. A junior engineer would check the percentage of cable slack using different graphs, calculator boards and the taut-wire gear. In the Testing Room the chief electrician and his assistants tested the cable using instruments like the mirror galvanometer. The testing Room was located on the spar deck below the bridge. In addition to the cable machinery, the ship was equipped with other ancillary apparatus. A large search lamp was normally located in the fore-deck to assist in operations to shore-end jobs. Large buoys (conical type) were used as markers and stored on the main deck. On the boat deck six small boats were available (one 18 ft gig, two 21 ft cutters, two 23 ft lifeboats and one 30 ft steam launch) The wireless room was located on the spar deck. The radio call sign of Pacific was OZI, later OZIB. Crew Expert telegraph engineer Raymond-Barker wrote once that "cable-laying viewed in its entirety affords a striking instance of well-organised division of important duties" The core staff was composed of Captain, five officers and five engineers. In addition, sixty locally recruited Chinese sailors were the manpower for the many jobs carried out on board. The Captain or Commander was responsible for navigation and general logistics. Danish technicians were in charge of the whole supervision of cable-laying and fault-tracing. The engineers put a great effort in keeping the boilers and steam engines in good working order. The daily fuel consumption was 27 tons of coal approximately. A memorable event for the crews of the CS Pacific and CS Store Nordiske was the Royal Visit of Prince Frederik to China in March 1930. Amongst the celebrations, the Great Northern Telegraph organised a ball and a dinner in the French Club to which the staff and the crew were invited. Amongst her captains were: E. Suenson (1905-1911), C. Tofte (1913–1915), H Petersen (1916-1918), H C A Petersen (1921-1923), Hans J. Christiansen (1919,1920, 1924-1931), J. B. Mathiasen (1932), E. Nielsen (1933) and August Vilhelm Nickel. In 1933, the Chief Officer was Axel Ingwersen winner of the 1924 winter Blue Water Medal. WW1 and WW2 In wartime the submarine cables and wireless stations suffered attacks in order to cut enemy's communications. This was the case in both wars
