| 摘 要： | 为了解决传统船型和已有圆柱筒状FDPSO的性能局限,提出一种具有沙漏型浮式主体的新概念FDPSO。为了满足深海海域系泊的需求,新概念浮体采用钢链-纤维缆-钢链三段组合式的绷紧系泊系统。根据深海绷紧式系泊系统中纤维缆的力学特性,对系泊系统动刚度特性进行了分析。在此基础上,在时域内求解系泊系统的动力响应,并采用T-N曲线法得到系泊缆在长期海况下的疲劳损伤,通过对结果的分析得到了一些有意义的结论,对今后工程应用具有重要参考价值。

| Abstract: | In order to solve the performance limitations of traditional ship-type and cylindrical FDPSO, a new concept of sandglass-type FDPSO is presented. For deepwater station keeping, the taut-wire mooring system, which the synthetic fiber ropes as the main part of the mooring lines, has been introduced to reduce the weight. According to the complicated mechanical properties of the fiber ropes, the analysis of the dynamic stiffness has been done. Furthermore, based on time domain analysis of the mooring system, T-N analysis has been applied for the fatigue damage assessment. These analyses provide significant reference for the engineering applications. |
