A survey is performed by reading the vessel’s draft markings at six standard points on the hull: forward, midship and towards both the port and starboard sides. Revisions for factors such as trim, water density and non cargo weight (such as fuel oil and drinking water) are changed before calculating the cargo weight change and calculating the final quantity by using the vessel’s approved dead-weight scales and tank tables.
Our Marine surveyors have extensive experience in this service and are available 24/7 to perform a draft survey and produce an independent report, based on the internationally standardized draft survey protocol.
When draft surveys are initiated by our surveyors, co-operation of the ship’s officers is essential. our surveys should be undertaken together, during the relative survey sections, with the vessel’s chief officer and chief engineer or their appointed deputies
