| 摘 要： | 本文将铺管船托管架联合体为研究对象,对100%装载铺管和10%装载铺管两个极限工况进行数值模拟计算。以此为数据基础,对铺管船铺管作业期间多个浪向下的水动力性能进行研究。通过多海况多浪向下的船舶运动计算结果对比,详细分析托管架对铺管船水动力性能的影响。结果托管架对于船体的垂荡运动的影响较大,并随浪向的变化而不同。且加装托管架后,船体的横摇运动大幅减弱。

| Abstract: | In order to study hydrodynamic performance of pipelaying vessel with stinger during operating, numerical simulations of motion response under different wave direction of hull under real operating conditions( 100% pipelaying and 10% pipelaying operation)were done in this paper. Analysis the change in hydrodynamic performance of hull after installing stringer by comparing the simulation data. Conclusions: Installing stringer has different effect on the heave of hull under various wave directions, and the amplitude of roll is reduced greatly. |
