NKK To Build First LNG Carrier To Use Technigaz Mark III Membrane-Type Cargo Tank System NKK Corporation recently an- nounced that it has received an order from Nippon Yusen K.K. (NYK) and Perbadanan Nasional Shipping Line Berhad (PNSL), Ma- laysia's leading shipping company, to build a 18,000-cubic-meter LNG (liquefied natural gas) carrier. The agreement was signed between NKK and NYK and PNSL, the ves- sel's joint owners, in Kuala Lum- pur. The carrier, which will have a steam turbine main engine, is to be built at NKK's Tsu Works, with delivery scheduled for July 1993. It will become the world's first LNG carrier to use the Technigaz Mark III membrane-type cargo tank sys- tem, based on technology licensed to NKK by France's Societe Nouvelle Technigaz in 1971. NKK's extensive LNG technology, developed over 20 years, will be incorporated in the building of the vessel. The 426-foot-long by 84-foot- wide LNG carrier has the following features: a compact hull form with- out unused space, ensuring high economic efficiency; freely selecta- ble hull design, enabling optimum tank size and shape; good bridge visibility; excellent maneuverability due to small sail area; easy mainte- nance due to low, flat upper deck; and complete double-hull struc- ture.
