Doc. 41/18Guidelines for Sea Transport of Multiple Element Gas Containers (MEGCS) and Portable Tanks for Gases


This publication provides guidance for the safe sea transport of portable tanks and multiple element gas containers (MEGCs) containing gases of Class 2 that are compressed, liquefied, or refrigerated.

The publication addresses product characteristics, general safety aspects, preparation for shipment, stowage on board ship, transport of containers, and emergency response to reduce the potential for unintentional releases of the contents for the duration of a defined journey, and to recommend actions in case of an accidental release.

Normally during sea transport, a skilled operator does not accompany these containers, so this publication has been written for the guidance of parties involved in their preparation and subsequent sea transportation.

This revised edition includes a number of amendments including holding time amended and the requirement to mark portable tanks that have a nitrogen shield

The publication is part of the programme to develop Globally Harmonised publications amongst Regional Gas Associations.
