该论文已在赫尔辛基举行的第28届CIMAC大会上发表，论文的版权归CIMAC所有。The seaborne transportation of Liquefied Natural Gas (LNG) is intensified, with the number of LNG carrier vessels sailing and on order steadily increasing. The current volatile global market and energy supply environment puts a pressure on LNG vessels to be more efficient, cost-effective and environmentally friendly. Modern LNG carriers feature complex and tightly integrated machinery systems to convert the on board primary energy sources to useful energy demands for propulsion, service electricity and heat. The main fuel source of LNG carrier is natural boil-off gas (BOG) from the cargo tanks with varying quantity and composition during voyage. The LNG ship energy system consists of various interdependent modules such as BOG compression trains, gas distribution and management, possible reliquefaction plant for the surplus BOG, prime movers, electricity generation / distribution networks as well as boilers for steam production. LNG carriers have also a time varying operational profile and trading patterns that affect LNG and BOG composition, hence affecting the energy efficiency of the integrated system. Therefore, the selection of the most suitable technologies and configurations for a particular ship is non trivial.
