中文摘要：

由于高强聚乙烯（HMPE）和聚酯（polyester）缆绳具有各自独特的材料性能,因此提出在超深水绷紧式系泊系统中,采用高强聚乙烯和聚酯组成的混合缆作为系缆。以一系泊在超深水处的FPSO为例,系缆分别采用聚酯缆绳、高强聚乙烯缆绳以及混合缆。比较了循环载荷作用下,不同绷紧式系泊系统的动力响应。分析表明,在超深水中采用混合缆能够设计出合宜刚度的系泊系统,使系泊系统既有保持海洋浮式结构物在平衡位置的能力,又有风暴载荷下良好的生存能力。较理想的混合缆构型是：在靠近海底部分,采用高强聚乙烯缆绳;而在靠近海面部分,采用聚酯缆绳。这些认识对混合缆应用于超深水绷紧式系泊系统具有重要的参考价值。

英文摘要：

Due to the special mechanical properties of high modulus polyethylene（HMPE） and polyester ropes,hybrid mooring lines that combine HMPE and polyester rope segments have been proposed as mooring lines of the ultra-deepwater taut-wire mooring systems.The dynamic analysis of a floating production storage and offloading（FPSO） unit is conducted to compare the dynamic response of the taut-wire mooring system with full polyester,full HMPE and with hybrid polyester and HMPE ropes.The analysis indicates that the benefit of hybrid mooring ropes is the ability for the mooring system designer to engineer the mooring line′s stiffness and use the lengths of polyester and HMPE segments to provide the stiffness needed to handle peak loads during station-keeping,while ensuring sufficient elasticity to withstand storms.These cognitions will provide significant reference for the application of the ultra-deepwater taut-wire mooring system with hybrid mooring lines which combine HMPE and polyester rope segments.
