Danish marine contractor Peter Madsen Rederi (PMR) has won a boulder clearance contract at the Ostwind 2 grid connection project in the German Baltic Sea.
German grid operator 50Hertz awarded the deal that includes extensive survey works at the three cable routes for the project, in addition to removal of surface boulders between landfall near Lubmin, in Mecklenburg-Vorpommern, and the offshore wind farm sites north-east of Rugen island.
Preparations have already begun and the project will be executed in 2019 following consents.
The Ostwind 2 grid connection will connect the 247MW Arcadis Ost 1, being developed by Parkwind, and the 476MW Baltic Eagle, being developed by Iberdrola, to the German high voltage grid.
PMR will use its own wire crane vessels as well as own multibeam survey equipment for the project.
The company has used a similar spread for other boulder clearance projects at other offshore wind farms, such as Arkona, Baltic 2 and Westermost Rough.
PMR has worked on 25 offshore wind farms in Denmark, the UK, Germany, Sweden, the Netherlands and France, spanning boulder clearance and repair of scour protection to seabed levelling and foundations ballasting.
