摘要:
为提高张力腿平台和立管与筋腱之间的动态耦合计算结果的准确性,更好地模拟平台的筋腱系统,运用势流理论,依据南海油气田开发既有资料,使用SESAM软件对一座传统型TLP平台张力筋腱进行分析。考虑筋腱和立管的实际工程设计,采用分段构建系泊系统的方法建立分析模型,并得到了频域下的附加质量系数和系统刚度矩阵。通过静水偏移模拟得到了平台系统水平及垂向刚度曲线和张力筋顶部张力,校验了系统质量和刚度的准确性。通过自由衰减模拟,验证平台固有周期,并采用规则波时域分析的方法求解了张力筋腱张力幅值响应算子(RAO)。结果表明,分段建模能很好地模拟实际工程中的张力腿平台(TLP)平台刚度,系统水平刚度与垂向沉降校验和自由衰减模拟可以更好地保证计算模型的正确性。
Abstract:
In order to improve the dynamic coupling calculation result accuracy of tension leg platform(TLP), risers and tendons, and to better simulate the tendons system of platform, this paper analyzed a traditional TLP tendon by using the SESAM software based on the potential flow theory and the oil and gas field development data on the south China Sea. The analytical model was established by using the method of subsection mooring system while considering the actual engineering design of the riser and tendon, the added mass coefficient under the frequency domain and system stiffness were calculated, getting platform horizontal stiffness and set-down curve and tendon top-tension by static offset simulation. The accuracy of the system quality and rigidity was verified. Then decay tests were performed in static water to verify natural period of the platform, and the tendon tension’s response amplitude operator(RAO) was calculated though regular wave time-domain analysis method. The results show that subsection modeling can simulate tension leg platform stiffness very well in actual engineering, the free decay simulation and verification of horizontal and set-down stiffness can better ensure correctness of the calculation model.
