Offshore wind turbines and their foundations are becoming larger and larger. This leads to contractors across the industry facing growing challenges because of their vessels’ increasingly limited capacities. To keep their current fleets efficient, innovative engineering solutions are vitally important. An example of these solutions is the upgrade of DEME’s heavy-lift jack-up vessel, Innovation. TWD engineers designed the first-ever skidding monopile seafastening on an installation vessel to handle the large foundations of the Galloper offshore wind farm. Together with the upend bucket and pile gripper, an integrated and future-proof monopile installation spread was realized. Our designs contributed to the smooth installation of the Galloper OWF (353 MW) that powers 380.000 houses with green electricity every year.
Next to the Galloper offshore wind farm, the monopile installation spread was also used on the following farms: Merkur, Rentel, Horns rev 3, Merkur, Hornsea 1, Seamade, Borssele, and Hornsea 2. We made small adjustments to accommodate each farm’s requirements.
