Project Description

Draft Survey

A draft survey is a calculation of the weight of cargo loaded or unloaded to or from a ship from measurents of changes in its displacement.

The draft survey is performed by reading the ship’s draft on the draft markings at six standard points on the hull: forward, midships and aft on both port and starboard sides. Corrections for factors such as trim, water density and non-cargo weight changes are made before calculating the cargo weight change.

A draft survey is a means of determining the weight of any materials being loaded into (or discharged from) a vessel. BritanniaAS’s experienced and highly qualified professionals can conduct a draft survey on your behalf and produce an independent draft survey report.
