The development and record of start-up of the Indonesia-Japan liquefied natural gas (LNG) trade are described. Characteristics of the eight U.S.-flag 125,000 cubic meter LNG vessels used in the trade, seven of which are dedicated to the project, are provided. Preparations to place these vessels in service included extensive crew training and proper outfitting of the vessels. The procedures for gas trials, which were conducted in England and Massachusetts, are discussed. Voyage characteristics of the vessels in the trade are provided. Improvements to the vessels based upon service experience include relocation of cargo discharge line check valves, extension of cargo tank fill lines, modification to cargo pump motor insulation, and several other modifications to cargo and ballast system components, the main reduction gear lube oil spray system, and internal components of the boilers. Design of the cargo control system and reliability in electronic control systems are the most critical factors in determining the operational effectiveness of LNG vessels. The service experience of these vessels reinforces the experiences of other operators, demonstrating that LNG vessels can be operated safely and reliably.
