Vattenfall on the Lookout for Boulder Clearance Crew

Vattenfall has invited companies to pre-qualify for boulder clearance work on the 605MW Kriegers Flak offshore wind farm in the Danish Baltic Sea.

The clearance of boulders would be carried out on the seabed at 72 wind turbine locations. The clearance is to be carried out with a vessel with a grab, and possibly by a plow at certain positions.

The contract would start on 31 August 2020 and end on 31 December 2020.

The tender will remain open until 8 November. Selected candidates will receive invitations to tender or to participate on 22 November.

The Kriegers Flak offshore wind farm will feature 72 Siemens Gamesa 8.4MW turbines installed 15-40 kilometres off the Danish coast and scheduled to be fully operational before the end of 2021.

Vattenfall has recently marked the start of construction of Kriegers Flak after the Rostock-based EEW Special Pipe Constructions GmbH started manufacturing the first monopile for the project.
