摘要
单点系泊系统通过动态定位使超级油轮无需靠港便可安全、稳定地完成原油装卸和储存,提高了海上石油运输的效率。本文选用一自调节弹性转台型单点系泊系统,在时域内计算在不同环境条件组合下的系统动力响应;探讨了水深变化对系统性能的影响。结果表明:自调节弹性转台型单点系泊系统在作业工况下系泊链受力满足规定的安全系数;处于环境条件入射方向上的系泊链组会受到较大的张力。水深变化影响了系泊系统性能,浅水条件下系泊链张力和系泊立管运动较大。
Single point mooring system enables super tankers to load,unload and store oil in a safe and stable manner without berthing through dynamic positioning,improving the efficiency of offshore oil transportation.In this paper,a Turret Mooring with Self Adjusting Stiffness(TUMSAS)single point mooring system is selected to calculate the dynamic response of the system under different combinations of environmental conditions in time domain.At the same time,the influence of water depth change on system performance is discussed.The results show that the TUMSAS single point mooring system meets the specified safety factor under working conditions,and the mooring chains in the incident direction of environmental conditions will be subjected to greater tension.The change of water depth affects the performance of mooring system,and the tension of mooring chains and the motion of mooring riser are greater in shallow water.
