Draught survey

The Draught Survey is the way to determine the amount of cargo loaded or discharged for the benefit of all interested parties. PESSANJ can provide the well conducted draught surveys having specially trained and highly qualified inspectors to determine the weight of cargo onboard vessels. There are many factors that impact on the vessels including the salinity of the harbor water, which will vary from port to port, ballast water contained in vessel’s ballast tanks that can have a significant impact depending on the density of the water used. Inspectors will need to determine the ‘constant’, which is difference between the theoretical and the calculated weight of the vessel and is made up of various weights such as sludge, stores and the crew. This forms part of the vessel’s history.
