Abstract:The offshore wind farms are expanding and shifting further offshore in deeper waters where the wind conditions are optimal, but on the other hand, operation and maintenance ships are facing the challenge of the harsh wave conditions. Service Operation Vessels equipped with motion compensation cranes and gangways are proven solutions to perform maintenance operations in harsh North Sea wave conditions. The focus in this thesis will be on designing a powertrain for a motion compensated crane capable of transferring personnel and heavy (> 1 ton) cargo between the vessel deck and offshore wind turbine. A model-based system engineering approach is applied to visualize the Motion Compensation Crane and to identify the functions, subsystems and actors and their relationships. Finally, a power train concept was developed that combined for a passive hydraulic cylinder and an active electric actuator into one hybrid actuator. A simulation of the loads acting on the power train, required actuator velocities during motion compensation operation of 3 hours was constructed. Next to this a proof of concept CAD model of the hybrid actuator for the boom and jib was designed that could withstand the induced loads and perform at the required actuator velocities.
