The vessel has been ordered by vessel operator Bernhard Schulte’s WINDEA offshore wind unit from shipbuilder Ulstein.
The SOV will be designed to GE Renewable Energy’s specifications, said a statement, including a large, centrally positioned walk-to-work motion compensated gangway and elevator tower for personnel and cargo transfers.
Due for delivery in early 2020, the vessel will be 93.4-metres long and 18-metres wide, with accommodation for up to 120.
Merkur will use 150 6MW Haliade machines from GE at its site in the German North Sea, with commissioning due later this year.
Developer Merkur Offshore named GE to deliver the project’s turbines in June 2015. A 10-year operation & maintenance service contract was included as part of the order.
