Study on vapour insulation technology in MOSS-type tanks of LNG carrier

Abstract

The paper introduces the importance of LNG carrier cargo tank insulation, the principle of vapour insulation technology and practical applications. Then, gives the vapour insulation mathematical model and the boil off rate calculation methods and through simulation of 125000 m 3 example of the mother-ship and the results comparison with the actual ship, reaches a conclusion that vapour insulation technology can reduce the boil off rate of tanks cargo greatly. Finally, provides vapour insulation system optimization design of the cargo tank. © 2011 Springer-Verlag.
