摘要
浅水中,单点系泊系统可能存在显著的低频运动,低频大幅运动响应会给系泊系统设计带来严重影响,是系泊系统设计的控制因素之一,在水动力性能预报时必须仔细予以考虑。针对HYSY113FPSO单点系泊系统在浅水风浪流条件下的运动性能进行了物理模型试验研究和数值对比,定量分析了低频运动的运动量和产生的原因,所得结论可供今后浅水水域塔架式单点系泊系统设计参考。
In shallow water, the low frequency （LF） motion of FPSO with SPM （Single point mooring） system may be significant, it is one of the governing factors at SPM design stage. Therefore, it should be taken into account carefully in the prediction of its hydrodynamic performance induced by low frequency wave component. Take HYSY113 as target FPSO, the global performance of the tower yoke SPM in shallow water is studied by model test and compared with numerical computation. The values of the low frequency motion and the reasons of the motion are analyzed The results and the conclusions can be used as reference in the future design of the tower yoke SPM in shallow water.
