Marine services & draft survey

Marine services & draft survey

Marine services within cargo surveying provide independent support during maritime operations. These services protect the interests of shipowners, charterers, cargo interests, P&I Clubs, and insurers. They help ensure that vessel operations run safely, efficiently, and in line with contractual and regulatory requirements.

A core marine service is the draft survey. This method determines bulk cargo quantities by calculating a vessel’s displacement. Surveyors take precise draft readings and measure ballast and bunkers. They also account for seawater density, trim, and vessel stability. When performed correctly, draft surveys offer a reliable and transparent basis for quantity determination and dispute prevention.

Marine services also include vessel condition surveys, hatch and hold inspections, tank inspections, and on/off-hire surveys. These inspections identify risks related to cargo integrity, vessel suitability, and operational safety. Surveyors perform them before, during, and after cargo operations.
