摘　　要：本文对码头系泊的FSRU和LNG船的水动力性能进行了研究,分别对FSRU单船码头和FSRU-LNGC并排码头系泊进行了模型试验。码头与船和船与船之间均采用系泊缆和靠垫进行连接。试验中考虑了风、流、浪等环境因素对码头系泊系统的影响。在风浪流模型试验中,分别测量了不同海况下系泊系统的动态响应,其中包括FSRU和LNG船的六自由度运动响应、系泊缆张力和靠垫接触力。相比较其它浪向,横浪(90°)引起的船舶运动更大,进而导致系泊缆和靠垫的受力增大。结果还表明,FSRU单船码头系泊在所有海况下安全性较好,但对于LNG船旁靠FSRU码头系泊系统,其对环境的响应非常敏感,尤其是横浪环境。An experimental investigation on the hydrodynamic performance of an FSRU(Floating Stor⁃age Regasification Unit)and an LNG(Liquefied Natural Gas)carrier moored at a quay is presented.Quay-moored model tests for the FSRU and side-by-side-moored model tests for the FSRU and LNG carrier are conducted respectively in a wave basin.Mooring lines and fenders are adopted to connect the quay and vessels.The effects of environmental factors of wind,current and wave are all considered during the tests.In the seakeeping model tests,the dynamic responses of the system,including the sixdegree-of-freedom motions of the vessels,tensions on mooring lines and contact forces on fenders,are measured in various sea states.Compared with waves of other directions,the beam sea waves contrib⁃ute to larger vessel motions,resulting in larger loads on mooring lines and fenders.The single FSRU quay mooring system has relatively calm responses among all the environmental conditions,whereas the side-by-side FSRU-LNGC quay mooring system is very sensitive to the environment,especially to the beam sea condition.
