This paper investigates the coupling between the suction bucket jacket foundation and the floating crane ship during the lowering process. The four-bucket jacket foundation of an offshore wind turbine is taken as the research subject. A coupled lowering model of the floating crane ship and the foundation is established using Sesam. The motion response of the coupled system and the tension response of the slings are analyzed for different sling layout configurations. The results show that the amplitudes of sway
roll
and yaw are higher for Type 3 and Type 4 configurations. This indicates that their stability is poorer compared to the other types. As the foundation sinks
the buoyancy force increases. This leads to a wider range of tension fluctuations in the slings before submergence. After full submergence
the tension fluctuation range decreases significantly. Type 3 and Type 4 configurations exhibit larger tension fluctuations due to lower sling stiffness and higher initial tension.
