自升式风车安装船升降室与导向结构强度评估

Strength Assessment for Jack House and Guides Structure of Jack-up WTIV

考虑到自升式风车安装船的升降室和导向结构在桩腿和主船体之间连接和传递载荷起关键作用,参考DNV海工规范要求并结合有限元直接计算方法,使用Genie软件对兼做吊车基座的左后升降室和导向结构进行有限元建模和应力分析,采用工作应力法评估目标结构的强度,得出升降室与导向结构基于强度设计的影响因素。

Considering that the jack house and guide structures in jack-up wind turbine installation vessel（ WTIV） play an important role to connect the legs and hull and transfer the interaction forces between them,it ＇s necessary to verify the yield strength of them. Referring to DNV offshore rules,the FE model of the jack house and guide structures,on which the main crane is mounted,is established in Genie,and stress analysis and assessment of yield strength for goal structure are carried out by working stress design（ WSD） method. Some influential factors for structure strength design are extracted.
