CONTROL SYSTEM FOR ACTIVE MOORING TENSION BETWEEN FSRU AND LNGC

摘要

PURPOSE: A control system for active mooring tension between FSRU and LNGC, capable of rapid reaction in emergency, is provided to keep the mooring state of LNGC about FSRU safe by maintaining the uniform interval of FSRU and LNGC. CONSTITUTION: A control system for active mooring tension between FSRU and LNGC comprises an interval sensor(110), an electric winch system(120), a tension detection sensor(130), a local control unit(140), and a main control unit(150). The interval sensor detects interval between LNGC and FSRU. The electric winch system is installed across the interval of FSRU and LNGC. The tension detection sensor is installed in a deck of FSRU and is connected to one end of a mooring chain(123). The local control unit receives each signal from the interval sensor and tension detection sensor and obtains mooring chain tension information and FSRU and LNGC interval information. The main control unit is installed in a control room located on the center part of the deck of FSRU.
