Class surveyors’ assistance to vessel. If a vessel has sustained damage to such an extent that her seaworthiness may be affected, the master will contact the surveyor of the classification society, in order to ascertain what repairs have to be carried out for the maintenance of class.

Contamination. If a cargo which is sensitive for some reason is damaged by the nature of another cargo or substance, the former is “contaminated”. This would be the situation if one grade of oil, e.g., a clean oil product on board a tanker, was loaded into a tank that was insufficiently cleaned.

Customary. This word usually refers to the rate at which cargo operations are to take place and may affect the time the vessel is made available by the owner for these operations.
