Study on Hydrodynamic Performance of Turret Mooring with Self Adjusting Stiffness Single Point Mooring System

WU Qiantong， WANG Dongjiao （SouthChinaUniversityof Technology，Guangzhou510641，China）

Abstract： Single point mooring system enables super tankers to load，unload and store oil in a safe and stable maner withoutberthing through dynamic positioning，improving the eficiencyofofshore oil transportation.In this paper，a Turret Mooring with SelfAdjusting Stiffness （TUMSAS）single point mooring system is selected to calculate the dynamic response of the system under different combinations of environmental conditions in time domain. At the same time，the influence of water depth change on system performance is discussed.The results show that the TUMSAS single point mooring system meets the specified safety factor under working conditions，and the mooring chains in the incident direction ofenvironmental conditions willbe subjected to greater tension.The change of water depth affects the performance of mooring system，and the tension of mooring chainsand the motion of mooring riser are greater in shallow water.

Key Words： single point mooring; lumped mass method; hydrodynamic; TUMSAS

1引言

單點系泊系統(tǒng)多應用在近海石油開采儲運中，可使浮式生產儲油系統(tǒng)（FloatingProduction Storage andOffloading，簡稱FPSO）等超級油輪無需靠港，只通過系泊纜或剛臂與單點系泊裝置連接，便可安全、穩(wěn)定地進行石油的裝卸和儲存，提高海上石油運輸的效率和靈活性。（剩余6133字）
