    Abstract：In order to respond to the trend of LNG receiving terminal built offshore，it is necessary to install low temperature subsea LNG pipeline between LNG receiving terminal and onshore pipeline network to transport LNG. Due to extremely low temperature of LNG storage and transportation，higher technical requirements shall be met for heat insulation and pipeline materials of low temperature subsea LNG pipeline than other oil or gas pipelines. Vacuum insulation blankets with extremely good adiabatic performance，or accumulated insulation blankets consisting of materials with extremely good adiabatic performance or nickel steel pipeline material with low thermal expansion performance shall be selected for fabricating such pipelines in order to meet such requirements. Generally，insulation blankets consisting of aerogel adiabatic materials or 9% nickel steel may be selected for fabricating low temperature subsea LNG pipeline.
