The floating LNG terminal consists of the jetty for floating storage & regasification unit（FSRU）and LNG vessel.For most overseas projects,the LNG vessel is moored outside the FSRU and there is no precedent in China.The two large LNG vessels are different from the conventional jetty and the cable forces and plane layout.According to the mooring project of a floating LNG terminal,the length of berth,the number of cables and the layout of the plane are analyzed and studied.For the jetty which are mainly affected by the wind and water flow,the spring lines of inside ship is the most stressed at full load.The following methods including increasing the number of bow and stern mooring lines of FSRU,increasing the jetty length and moving forward the dolphin for bow and stern lines to reduce the bow and stern line horizontal angle and arranging the mooring line symmetrically will ease the spring lines.The cables should be symmetrical arranged.
