The Moss Rosenberg Verft spherical tank type LNG containment system, defined as an independent type B tank stipulated by IMO Gas Code, is required to be designed by the precise strength analysis method. For the theoretical aspect of the analysis method, reference should be made the literatures. This paper presents the results of full scale measurements during the tank's structural test and cooling down test which were carried out prior to the ship's delivery in order to verify the theoretical studies and also to confirm the reliability of the analysis method. Major conclusions are as follows. (1) The accuracy and reliability of the analysis method are verified through the close agreement between the results of measurements and predictions in every instance, such as static stresses, temperature and thermal stress. (2) Structural safety of the LNG carriers designed based on this analysis method is therefore established.
