This unique guide explains how good shipboard survey practice can significantly reduce the risk of shortage or contamination claims arising from loading or discharging crude oil and petroleum products. A range of quantitative and qualitative monitoring and recording techniques is recommended which should ensure that potential loss or contamination problems are identified at an early stage and can be remedied cost effectively. The guide is aimed at ship’s officers, cargo surveyors and all others involved in monitoring cargo operations. The second edition has been updated and revised to reflect the latest industry developments.
