海上风电安装船主要在海上风电场作业，作业工况多，风浪载荷大，风暴自存是其最危险的状态，环境载荷达到最大值。针对风暴自存状况，文章分析了海上风电安装船在此状态下的受力特点，建立了全船结构模型，对主船体及桩腿进行了结构应力水平分析，得到了在风暴自存状态下的应力分布及变形特点。对比常规工作工况，风暴自存状态下应力水平以及位移均有显著提高，特别是在桩腿与主船体连接处需进行局部加强。

The offshore wind turbine installation vessel mainly works in the offshore wind farm with differ-ent working conditions and large environment loads. The survival condition is its most dangerous state, and the environment load is at its maximum value. Aiming at an offshore wind turbine installation vessel under the survival condition, its loading feature was analyzed, the FEM model was built up, the structural strength of its main hull and legs were analyzed, and the stress distribution and deformation were obtained. Compared with its operative condition, the stress level and deformation under the survival condition were enhanced re-markably, especially the joint between the hull and its legs needs local reinforcement.
