BURAN REFRIGERATION COMPLETE AIR DRYERS

There have been so many publications about the carriage of the first cargoes of liquefied natural gas (LNG) onboard the Methane Pioneer in 1959. But what of liquefied petroleum gas (LPG), a gas ship cargo which predates LNG? When were the pioneering LPG cargoes carried and how did this important seaborne trade develop? In this tribute to the first gas carriers, Robin Gray, former SIGTTO General Manager, sheds light on the early days of the less well-known part of the gas shipping industry and on the role played by one particular shipyard in the North East of England.

This paper by Robin Gray, former general manager of SIGTTO, provides some historical background, touching the post-war development, addresses the major conversions of the vessels and famous conversion projects, applicable rules and patterns, liability insurance and cargo familiarity, material used for the construction and insulation of the cargo tanks, integrated gas distribution, propane loading problems, local gas trials, ethylene-related issues, training provided to the officers, fire protection tests, cooldown tanks, welding problems etc. Have a look into this document since the information contained in it is useful and practical.
