中文摘要:
      针对圆筒型海上储油装置FPSO垂荡运动性能较差、无法安装干式井口的问题,设计了带延伸筒体与矩形阻尼结构的圆筒型FPSO,根据延伸筒体与矩形阻尼结构是否通海分为两种型式。建立水动力计算模型,比较分析不同延伸筒体和阻尼结构型式对FPSO水动力性能的影响。针对南海作业海域,设计了悬链式系泊系统,基于JONSWAP波浪谱对FPSO的运动进行时域预报,并对系泊系统进行校核。分析结果表明:通海型FPSO垂荡固有周期显著提升,可以错开南海百年一遇谱峰周期,通海型FPSO满足钻井、安装干式井口的运动响应要求,系泊系统系缆张力满足规范要求。
英文摘要:
      In order to solve the problem of poor heave performance of floating production storage and offloading (FPSO) and the inability to install dry wellhead, a cylindrical FPSO with an extended cylinder and rectangular damping structure was designed. The cylindrical FPSO is divided into two types according to whether the extended cylinder and rectangular damping structure are free-flooding. The hydrodynamic model is established to compare and analyze the influence of different extended cylinder and damping structure on the hydrodynamic performance of FPSO. With regard to the South China Sea, a catenary mooring system was designed to predict the motion of FPSO in time domain based on JONSWAP wave spectrum, and the mooring system was checked. The result shows that the natural period of heave of the cylinder FPSO with free-flooding extended cylinder and damping structure is significantly increased and make it far from the sea wave spectral peak period of once per one hundred years sea conditions; the cylinder FPSO with free-flooding extended cylinder and damping structure can meet the motion response requirements and the mooring system can also meet the requirements of the specification.
