It recommends procedures and formulas for every circumstance likely to be encountered.The purpose of a draught survey is to determine the amount, of cargo loaded or discharged for the benefit of all the interested parties. A well-conducted draught survey of a large vessel should achieve accuracy to within 0.5%.The survey must be conducted meticulously, raking into account all the prevailing circumstances. The final report should incorporate every aspect and difficulty which 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 permit a draught survey to the same degree of accuracy.
