‘Seajacks Scylla’, the world’s largest wind turbine installation vessel recently placed 67 XXL monopiles into the seabed of the offshore German wind farm Veja Mate using a double pile gripper frame.
Together with the two main subcontractors DGI Doedijns and Breman Machinery, Euro-Rigging was the turnkey (EPC) contractor for this complex, double pile gripper frame for placing the piles. Thanks to the tight project management of all three companies involved, the frame has been delivered and installed on the Scylla in a record time schedule.
Due to the size and weight of these XXL monopiles basically two gripper arms were placed above each other to jointly position the pile. To prevent seastate motions from causing possible instability, the gripper frame was equipped with a hydraulic motion compensation system. The turnkey delivery was done by Euro-Rigging, Breman Machinery assembled the frame and DGI Doedijns was responsible for the hydraulic and electric integrations of the gripper. With this challenging project, the three companies have proven their skills and expertise and are very satisfied with their collective contribution. The project required tailor-made solutions and this made the double pile gripper a high end technical piece of workmanship!
