半潜坐底式海上风电安装船设计与开发

适用于海上浅水区域作业的半潜坐底式海上风电安装船具有安全性好、施工效率高和成本低等特点，其设计的特殊性在于需要考虑海流冲蚀泥沙导致的坐底面积丧失。以开发的一艘典型实船为例，阐述主要功能，提出坐底稳定性应考虑的两种工况，采用有限元计算对坐底工况结构强度进行校核，对在软泥和粉砂两种地质条件下进行作业给出应对措施，可为同类型船的设计提供一定技术参考。

Design and Development of Semi-Submersible Bottom-Supported Offshore Wind Turbine Installation Vessel

The semi-submersible bottom-supported offshore wind turbine installation vessel suitable for the operation in offshore shallow water area is of the characteristics of good safety, high construction efficiency, and low cost, and the particularity of its design lies in the need to consider the loss of sit-on-bottom area caused by the ocean currents eroding sediment. Taken a typical actual ship developed as an example, the main functions are expounded, two operation conditions that should be considered for the sit-on-bottom stability are proposed, the structural strength of sit-on-bottom operation condition is checked with the finite element calculation, and the corresponding measures are given for the operation under the two geological conditions of ooze and silt, which can provide certain technical reference for the design of same type of vessels.
