单点系泊系统系泊力响应特性分析

摘要

为了得到单点系泊油轮在浅水域的安全装载方案,通过水平刚度物理模型试验与数值模拟得到了系泊系统刚度的影响参数,通过风浪流联合作用工况试验得到软刚臂水平系泊力响应.对船体吃水与软钢臂压载舱重的工作参数对水平系泊力的影响进行了分析.进一步地,对浅水不规则波的周期、非线性及低频等特征参数对系泊力的影响进行了讨论.%In order to complete safe loading solutions for a tanker berthing by adopting single point mooring method in shallow water, firstly a physical model test of horizontal stiffness is combined with numerical simulation to get the influence parameters for the stiffness of mooring system, and the work condition under the combined action of wind, wave and current is tested to obtain the horizontal mooring force response of mild steel beam. Secondly, the influence of working parameters on the horizontal mooring force is analyzed, which involve the draught of ship hull and ballast weight of mild steel beam. At last, a discussion is made to study the mooring force being affected by the characteristic parameters of irregular wave in shallow water, i.e. period, nonlinearity and low frequency etc.
