摘      要：When a maintenance and operations ship is berthing,there is a chance the ship may collide into the wind *** these ships collide into wind turbine structures,this can result in significant changes to the foundation and structure of the wind *** this paper,the structural load of a 4 MW offshore wind turbine was analyzed during a collision with an operations and maintenance *** variations in the wind speeds on hub height,waves,and the sea currents were *** dynamic simulation of the wind turbine was carried out using the test data as the input *** a result,the load condition of the turbine without a collision was ***,the measured turbine load was compared with the simulation *** study shows that the collision of the operation and the maintenance ship increases the bending moments at the tower’s bottom and the blade’s roots.
