SNAME Publishes 'Gas Trials Guide For LNG Vessels'

Of highest interest in the marine field today is the design and construction of many specialized ships that carry cargoes of liquefied natural gas (LNG). Major shipyards in the U.S. and other countries are engaged in building these giant carriers. For some time there has been a need for a guide or handbook to help the builder try out and prove the cargo piping, pumping equipment, and tanks at dockside. Panel MS-8 (Special Cargo Systems) of the Society's Marine Systems Committee has long recognized this need and has now published, through SNAME's Technical and Research Program, the 20-page "Gas Trials Guide for LNG Vessels." This guide provides definitive information on the preparation for gas trials, and the conduct of those trials.

It covers procedures for drying and inerting, cold testing of deck machinery and piping, displacement of inert gas and cool-down of the tanks, LNG handling, boiloff handling, warm-up and gasfreeing. In addition, there is a section giving information for the first full load.

Panel MS-8 is comprised of representatives of American shipbuilders, shipowners and operators, the Maritime Administration, the American Bureau of Shipping, the U.S. Coast Guard, and other experts of the LNG industry.

Technical and Research Bulletin 5-2 (Gas Trials Guide for LNG Vessels) is available from the Society at $6 per copy if payment accompanies the order. Society member price is $4.
