for Bulk/Grain Cargo. Their job is to perform a draft survey to determine the actual cargo loaded on board. They also confirm that the cargo loading is performed according to the law and is within the loadable limits. The vessel safety is also ascertain which includes momentum due to cargo shift which may render the vessel unsafe during the passage. Often high value commodities are witnessed during load out especially if they are contamination sensitive. Classification surveyor A classification surveyor inspects ships to make sure that the ship, its components and machinery are built and maintained according to the standards required for their class. Classification surveyors most generally have two roles: one is a representative of the classification society; and the other as an inspector on behalf of the country with which the vessel is registered (the flag state). The classification role is to ensure that during construction the vessel initially complies with the classification society's rules for construction and outfitting, and thereafter is maintained fit to proceed trading. The Flag State role is based on a clear set of guidelines issued by the registering country. On satisfactory completion of any survey, the classification surveyor makes recommendations to the classification society and/or the flag state. These may be that the vessel has a clean bill of health, or that various defects must be corrected within a given time. Increasingly, both government and classification surveyors are becoming involved in confirming compliance with international treaties associated with such things as pollution, international security, and safety management schemes. They may also examine cargo gear to ensure that it meets various requirements or regulations. Government and classification surveyors are usually marine professionals mariners, such as a qualified ship's master, engineer, naval architect or radio officer.

Independent surveyors also carry out condition surveys or per-purchased surveys (also known as "Condition and valuation" survey (C&V)) to determine the condition of the ship prior to charter or an acquisition.
