摘要
推进器辅助锚泊定位是一种将锚泊定位和推进器定位相互结合的新型混合定位系统。论文建立了在风浪流海况作用下船体—锚泊—推进器三者联合作用的时域响应数学模型,运用时域评估方法对推进器辅助锚泊FPSO艏向控制模式进行了研究。计算分析了推进器辅助锚泊定位下FPSO在共线和非共线风浪流海况作用下的运动性能,并与锚泊定位进行了对比。研究结果表明,艏摇角对FPSO摇荡运动影响显著,推进器辅助锚泊定位可以显著提高FPSO艏向控制精度,有效改善FPSO运动性能,提高整个系统的安全性。
Thruster assisted mooring is a new type of hybrid positioning system that consists of mooring lines and thrusters.A mathematical model in the time domain is established in this paper,in which the combined actions of the floating body,mooring lines and thrusters in waves are involved.Heading control mode of FPSO with thruster assisted mooring is studied by dynamic evaluation method.Motion performance of FPSO with thruster assisted mooring under the collinear and non-collinear environments is analyzed respectively,and is compared with the mooring positioning.The results indicate that the effect of yawing angle on the motion of the FPSO is considerable.It is also indicated that thruster assisted mooring positioning can significantly improve the precision of heading control of the FPSO,and effectively improve motion performance of the FPSO and enhance security of the whole mooring system.
