摘要:

从船型、环境条件和设计工况考虑,定性地为八角形浮式钻井生产储卸装置(FDPSO)选择等角度分组张紧式系泊系统。以2 000 m水深处环境条件为基础,设计了一套等角度分组张紧式系泊系统,以满足八角形FDPSO的定位要求和系泊线受力要求。与悬链式系统相比,张紧式系泊系统垂向重量小,锚泊半径小,百年一遇海况下一根锚链破损之后FDPSO的水平偏移能够得到有效控制。所提出的系泊系统不但可以满足八角形FDPSO系泊定位的要求,而且可为类似浮体的深水系泊设计提供参考。

Abstract:

The existing mooring systems are compared and analyzed with the consideration of vessel shape, environmental condition and design cases. Average-distributed taut mooring system is finally selected for the octagon floating drilling, production, storage and off loading system (FDPSO) in the South China Sea. According to the requirements of station keeping and line forces, an averaged-distributed taut mooring system is designed based on the environmental condition at the depth of 2 000 m in the South China Sea. Compared with the traditional catenary mooring system designed for the same FDPSO, the averaged-distributed taut mooring system reduces the mooring system self-weight and the mooring radius on seabed. In addition, the offset of FDPSO with one mooring line damaged can be efficiently managed under 100-year environmental condition. The proposed mooring system can meet the requirements of octagon FDPSO. Furthermore, the research results will offer references for the mooring design of similar floating structures.

Key words: mooring system, floating drilling, production, storage and off loading system (FDPSO), taut mooring, catenary mooring
