The purpose of a draught survey is to determine the amount of cargo loaded or discharged for the benefit of all interested parties. A well conducted draught survey of a large ship should achieve accuracy to within 0.5%. The survey must be conducted meticulously, taking into account all prevailing circumstances. The final report should incorporate every aspect and difficulty that has been encountered in order to convey all aspects of the survey. While draught surveys may be carried out by professional surveyors, the ship’s officers should also perform a draught survey to the same degree of accuracy. It is hoped that this guide will assist in achieving the required standards.
