Viewing the roll of the insulation for LNG Carrier, such as to avoid the excessive low temperature of the adjacent inner hull beyond the permissible limit and to maintain a proper boil off rate of cargo, evaluation of performance of insulation system prior to entering into the actual service is very important. At the same time an economical achievement of the LNG transportation at sea and the safety of the ship are also connected with the performance of the insulation system. The final cooling down test of cargo tanks with LNG may, however, be too late for this evaluation due to the limited time available for the necessary modifications or repairs before delivery of the ship. Authors have established the test method for confirmation of insulation properties for the independent tank system, which include the inspection and evaluation of various defects which directly influence on the performance of insulation, during the erection stage of the ship. The most part of performance of insulation during actual low temperature service could be evaluated at the normal temperature according to this procedure. Authors have applied this method to the actual tank and got a good coincidence between the estimated and actual phenomena.
