Boskalis has secured a multi-disciplinary role in developing Scotland’s Moray West offshore wind farm. On behalf of its client, Boskalis will carry out a large number of activities contributing to the development of this renewable energy project in the coming 12 months. The sizable contract was awarded by Ocean Winds, the 50:50 joint venture between EDP Renewables and ENGIE dedicated to offshore wind energy.

The Moray West offshore wind farm is located off the east coast of Scotland in the Moray Firth. The 882 MW wind farm will have the capacity to power up to 640,000 homes in the United Kingdom. The development consists of 60 offshore wind turbines and two substations, all fixed on monopile foundations. Based on the large turbine size (14.7 megawatts) and water depth (up to 54 metres), extremely large XXL monopiles weighing up to 2,000 tons each will be required for this development.

Boskalis has been able to offer a broad range of its capabilities in this project and has already carried out an offshore geophysical site survey that also included a survey to identify unexploded ordnance.

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. Eight monopiles 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’ strategy is aimed at leveraging on key macro-economic factors which drive worldwide demand in our markets: expansion of the global economy, increase in energy consumption, global population growth and the challenges that go hand in hand with climate change. This project is related to the development of generating renewable energy due to climate change and increasing energy consumption.
