The accurate measurement of dry bulk cargoes by a ship considerably minimises the risk of shortage claims and disputes. This guide outlines the methods and corrections for a draught survey to be carried out to the required accuracy. It is supported by draught measurement calculations and illustrations which show best practice.
This publication is useful to surveyors as it recommends procedures and formulae for every stage of a draught survey. Practical guidance is given through worked examples, such as those relating to the misplacement of draught marks. UN ECE draught survey forms have been included to encourage standardisation throughout the industry.
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.
