MODEL EXPERIMENT AND COMPARATIVE FINITE ELEMENT METHOD CALCULATION FOR A MOSS TYPE LIQUEFIED NATURAL GAS CARRIER
The carriage of liquefied natural gas (LNG) at a temperature of -162 Centigrade is one of the most interesting fields of todays shipbuilding technology. The cost of these ships is large, in the order of 70 to 90 million U.S. dollars. Thus the LNG-carrier design field at Det Norske Veritas has been one of the testing grounds for large scale application of the powerful Finite Element Method for static and dynamic structural analysis. During the original design of the Moss-Rosenberg spherical tank LNG-carriers the Finite Element Program system SESAM-69 was an absolutely indispensable tool. For the 129000 m cubed Moss-Rosenberg type LNG-carriers for Kawasaki Heavy Industries it has also been extensively used for several of the main design calculations. The computer results were compared to strain gage tests on a 13.75 meter model with interesting but satisfactory results.
