A marine surveyor is a person who inspects, surveys, or examines marine vessels in order to assess damage, inspect aberrations, or monitor their condition and that of any cargo on board. Marine surveyors also inspect equipment intended for new or existing vessels to ensure compliance with various standards or specifications. Marine surveys typically include the structure, machinery, and equipment in addition to the general condition of a vessel and/or cargo. They also involve judging materials on board and their condition. Though a largely unregulated profession, marine surveyors are generally trained specifically for the role and usually selected after thorough evaluation procedures. Their duties apply to a wide range of seafaring vessels.
