Update: Supplement for the Crude Oil Washing Systems, 2000 Edition, has been published and is available to download  here

 

Regulation 13 of Annex I of MARPOL 73/78 requires certain ships to operate with a cargo tank cleaning system using crude oil washing. The crude oil washing installation, assocaited equipment and arrangements must meet requirements established by Administrations based on specifications originally adopted by the International Conference on Tanker Safety and Pollution Prevention in 1978. These specifications have been amended and modified on several occasions since 1978, and this publication contains the most up-to-date version, along with various related texts.

This publication contains: * Revised Specifications for the design, operation and control of crude oil washing systems (resolution A.446(XI), as amended by resolutions A.497(XII) and A.897(21)); * examples of Crude Oil Washing Operations and Equipment Manuals; * Guidelines for in-port inspection of crude oil washing procedures.
