COMMUNICATION SYSTEM BETWEEN LNG STORAGE FACILITIES, LNG TERMINAL AND LNGC RV

摘要

PURPOSE: A communication system between an LNG(Liquefied Natural Gas) storage device of an LNGC RV(LNG Carrier Regasification Vessel) and a place where LNG is used is provided to reduce the costs and time for restarting of equipment by selectively cutting off the supply of LNG from the LNG storage device and regasification of LNG from the LNGC RV in an emergency shutdown situation. CONSTITUTION: A communication system(100) between an LNG storage device(20) of an LNGC RV(10) and a place(30) where LNG is used comprises first through third communication systems(110,120,130) and an emergency shutdown system(140). The first communication system is installed in the LNG storage device and communicates with the LNGC RV. The second communication system is installed in the place where LNG gas is used and communicates with the LNGC RV. The third communication system is installed in the LNGC RV and communicates with the first and second communication systems. The emergency shutdown system is installed in the LNGC RV and communicates with the third communication system. When an emergency shutdown situation occurs in the LNGC RV, the LNG storage device, or the place where LNG gas is used, the emergency shutdown system receives an emergency shutdown signal and selectively stops the supply of LNG from the LMG storage device and the regasification of LNG from the LNGC RV.
