摘　　要：海上风机吊装船是具备运输、起重功能的用于海上风电设备安装的海洋工程船。本文将1艘半潜驳船改装成海上风机吊装船,利用有限元软件对该船在拖航、坐底及吊装等典型作业工况下的结构强度进行计算分析,得到船体结构的应力分布及变形情况。计算评估方法和结果可为半潜驳改装海上风机吊装船的结构强度评估、改装方案可行性论证提供依据,也对类似船舶的改装设计开发具有参考价值。The offshore wind turbine installation vessel is a type of ocean engineering vessel with carriage and lifting functions for offshore wind power equipment installation.In this paper,a Semisubmersible barge was retrofitted into an offshore wind turbine installation vessel.By analyzing typical operation conditions of trailing and diving,the stress distribution and the deformation are obtained with the help of finite element model.The evaluation method and calculation results are helpful for structural strength assessment and retrofit plan feasibility study of this vessel,as well as the retrofit design and development of similar vessels.
