风电场安装船为多腿浮式结构。水下支腿对舰船在波浪作用下的响应有显著影响。其主要原因是水下支腿的存在导致了不同于一般无支腿船舶的水动力特性。为了分析水下腿对水动力响应的影响，根据腿在水下的长度对五种情况进行了分类。然后，应用三维势理论对结构在不同情况下的水动力响应进行了数值模拟。计算并比较了6个自由度在不同波浪频率下的水动力系数、波浪激励荷载和RAO。结果表明，除了浮体的升沉运动外，水下支腿对多腿浮体结构水动力响应的影响是明显的。
The wind farm installation vessel is a floating structure with multiple legs. The legs underwater have a prominent effect on the responses of the vessel on waves. The main factor is that the existing of the legs under water leads to the hydrodynamic characteristics different from the normal vessel without legs. To analyse the influence of the legs underwater on the hydrodynamic responses, five cases are classified according to the length of the legs under water. Then, the hydrodynamic responses of the structure in different cases are numerically simulated by applying the three-dimensional potential theory. The hydrodynamic coefficients, wave excitation loads and RAOs of the six degrees of freedom in different wave frequencies are calculated and compared. The results show that the effects of the legs underwater on the hydrodynamic response of a floating structure with multiple legs are visible except for heave motion of the floating body.
