Abstract

The structure of B type LNG carrier was introduced

and the calculation model was established.Then

the distribution of temperature field and velocity field and heat transfer calculation were analyzed in six kinds of conditions using the method of CFD numerical simulation.In addition

the boil-off rate in different conditions was calculated.The results show that the boil-off rate of the LNG carrier was no more than the goal of 0.1% per day when the thickness of the insulating layer was 350 mm and the LNG tanker system was intact.The research results provided an important reference and consulting for the supporting system of insulation design and innovation of LNG carrier.
