摘　　要：由于“奋力号”打捞船的用途特殊、自带开底月池且L/B>5及B/D≤2.5,已不满足采用规范公式计算波浪载荷的条件,故需进一步用直接计算的方法确定其波浪载荷。以“奋力号”为例,简要介绍利用三维频域线性水动力计算软件SESAM,计算“奋力号”在调遣和工作工况时,波浪弯矩和波浪剪力的长期及短期预报值,并与规范公式计算的波浪弯矩剪力值进行对比,为后续“奋力号”全船结构强度有限元分析中波浪载荷的施加提供依据。Due to the special use of the salvage vessel Fenlihao,which has a self-contained open bottom moon pool and L/B>5 and B/D≤2.5,it no longer meets the conditions for calculating wave loads using standard formulas.Therefore,it is necessary to further determine its wave loads using direct calculation methods.This paper takes the Fenlihao as an example to briefly introduce the use of the three-dimensional frequency domain linear hydrodynamic calculation software SESAM to calculate the long-term and short-term forecast values of wave bending moment and wave shear force of the Fenlihao in dispatch and work conditions,and compares them with the wave bending moment and shear force values calculated by the standard formula,providing a basis for the application of wave loads in the subsequent finite element analysis of the overall structural strength of the Fenlihao.
