Boskalis has secured a multidisciplinary contract from Ocean Winds, the 50:50 joint venture between EDP Renewables and ENGIE, related to the development of the 882 MW Moray West offshore wind farm in Scotland.
On behalf of its client, Boskalis will carry out a large number of the activities contributing to the development of this renewable energy project off the east coast of Scotland in the Moray Firth in the coming 12 months. Moray West offshore wind farm will comprise sixty Siemens Gamesa SG 14-222 DD 14.7 MW wind turbines and 2 substations on monopile foundations and will have the capacity to power the equivalent of up to 640,000 UK homes. Based on the large turbine size and water depth (up to 54 meters), large XXL monopiles weighing up to 2,000 tons each will be required for this development.
Boskalis already carried out offshore geophysical site survey that also included survey for identification of unexploded ordnance (UXO). In the coming months, Boskalis will transport a large number of the monopiles from the Far East to discharge at the port of Invergordon, near the project site. These monopiles – eight per voyage – will be transported on the heavy transport vessel White Marlin.
Prior to the installation of the foundations, Boskalis will carry out the seabed preparation activities by installing a layer of rock that will act as a filter and scour protection for the monopiles.
Subsequently, Boskalis will deploy its DP crane vessel Bokalift 2 for the installation campaign. With its 4,000-ton crane the Bokalift 2 will install the monopiles using its new upending hinge and motion-compensated pile gripper. Furthermore, in addition to a very large impact hammer, Boskalis will also deploy a vibro-hammer on this project. As a part of its campaign, Boskalis will also install two substations with their respective transition pieces. Boskalis did not state the exact value of the contract but mentioned it is between EUR 50-150 million. Source: Boskalis
