介绍了浮式生产系统（包括船舶、系泊系统和立管系统）的全耦合全局分析。系统的设计可能是一项艰巨的任务，涉及1000多个载荷工况进行全局分析。系泊系统和立管系统的主要驱动力是船舶的运动。船舶运动由环境力驱动，但受到系泊和立管系统力的约束。数值模型和程序，提供准确和有效的浮式生产系统的全球建模。包括时域和频域程序。一个例子说明了程序的准确性和效率：一个大型半16个系泊缆和20海里。该程序提供了在浮式生产系统的设计中使用全耦合分析的准确性和效率，从概念选择到最终设计，安装和操作。
Fully coupled global analysis of Floating Production Systems, including the vessel, the mooring system and the riser system is described. Design of the system can be a daunting task, involving more than 1000 load cases for global analysis. The primary driver for the mooring system and for the riser system is motion of the vessel. Vessel motions are driven by environmental forces, but are restrained by forces from the mooring and riser systems. Numerical models and procedures that provide accurate and efficient global modeling of the Floating Production System are presented. Both Time Domain and Frequency Domain procedures are included. The accuracy and efficiency of the procedures are illustrated in an example: a large semi with 16 mooring lines and 20 risers. The procedures provide the accuracy and efficiency for use of fully coupled analysis in design of Floating Production Systems from concept selection to final design, installation and operation.
