This book recommends a range of quantitative and qualitative monitoring and recording techniques to ensure that potential loss or contamination problems are identified at an early stage and can be remedied cost effectively. The guide is aimed at ships’ 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.

This 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. The large volumes involved and the many potential errors that can arise during custody transfer mean that close supervision is vital to avoid costly and time consuming disputes. The guide is intended primarily for ships’ officers but will also be of value to cargo surveyors and others involved in monitoring oil cargo operations.

A range of quantitative and qualitative monitoring and recording techniques is recommended and should ensure that potential loss or contamination problems become apparent at an early stage and can be remedied at a low cost. Should problems remain undetected and claims subsequently arise, the monitoring will at least ensure that relevant shipboard factors can be identified, assessed and – when unfounded – used to exonerate the ship. The guide is intended to complement standard industry guidelines and procedures, not replace them.
