Cargo Guidelines for F(P)SOs

2018 Edition, Oil Companies International Marine Forum, ISBN: 978-1-85609-764-2

This new publication offers guidelines for safe cargo handling and associated operations on board F(P)SOs. It supplements existing guidance in the International Safety Guide for Oil Tankers and Terminals (ISGOTT), by addressing activities and procedures that are either outside the scope of ISGOTT or are conducted differently on F(P)SOs, which often have multiple operations taking place at the same time. This publication will be essential for F(P)SO operators, as well as anyone involved in their design and management.
