摘　　要：针对新概念FPSOIQFP（圆角倒棱台形FPSO）的浮体特点以及边际油田经济性开发的需要，论文旨在设计一套经济有效的多点系泊系统。首先，将钢制悬链线系泊系统和聚酯纤维张紧式系泊系统作为备选方案，根据定常力计算结果并参照工程经验，给出两种系泊系统的初始设计方案，并进行二者的静特性分析，探讨系泊参数对系泊系统受力和位移的影响规律，在此基础上，结合时域计算结果，确定系泊系统的优化设计方案，最后，给出系泊系统的回复力和浮体位移之间的关系曲线，并在静力范围内比较两种系泊系统的优劣。静力分析结果初步验证，较之悬链线系泊系统，张紧式系泊系统用于浅水作业的IQFP上更具优越性。In order to design an effective and economical multi-point mooring system for the new concept FPSO IQFP （fillet inverted quadrangular frustum pyramid shaped FPSO, presented by the author）, effects of mooring parameters on performance of catenary mooring system and taut mooring system were investigated. Then, optimal mooring systems were developed on the basis of static analysis combined with corresponding calculations in time domain. Characteristic parameters as well as the curves of restoring force against horizontal displacement for both of catenary and taut mooring systems were obtained. Then the merits and demerits of the two mooring schemes were compared .The results verify that taut mooring system is preferable to catenary mooring system for IQFP deployed in shallow waters.
