摘要
选取1 500 m的Spar平台工作为例,分析其绷紧式系泊系统的静力特性,并开发了以C++语言为基础的程序,用于计算单根纤维系缆张力、系泊系统的总水平恢复力-位移特性和总垂直恢复力-位移特性。建立海底等效弹簧模型分析不同海底地形对单根系缆的张力-位移特性的影响,重点研究了不同海底弹性基础的系缆张力、系泊系统总水平和总垂直恢复力-位移特性,为绷紧式系泊系统的数值分析及理论研究奠定了一定基础。
Take a 1 500 m spar platform as an example, this paper carries out the analyses of static performance of its taut-wire mooring system, and develops a C＋＋program for the calculation of axial tension of each cable, and the overall horizontal and vertical restore force and the displacement characteristics of the mooring system. An equivalent spring model is built to analyze the inlfuence of different submarine topography on the static performance of each cable. It focus on the cable tension, and the overall horizontal and vertical restore force and the displacement characteristics of the mooring system of the different submarine elastic foundation, which provides a certain foundation for the numerical analysis and the theoretical research of the taut-wire mooring systems.
