Abstract: 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.
