Maersk Offshore Wind’s installation vessel launched

Wind Energy – Launch

Maersk Offshore Wind’s installation vessel marked a milestone with the float out of the ship from the Seatrium shipyard in Singapore.

The vessel is being built as part of the group’s efforts to develop the offshore wind sector, but conceived with the U.S. market as its target, it is unclear how the vessel will be deployed.

The ship is designed to be positioned at the offshore wind farm development site and be fed by two specially designed barges carrying the material and brought to the site by tugs. The WTIV has a stabilizing system to hold the barges for the transfer of materials.

 The company has promoted that this would improve installation efficiency by up to 30 percent and critically would make the system compliant with the U.S. Jones Act which limits coastal operations for foreign vessels. Maersk’s WTIV will be registered in Denmark.

The installation vessel, which is approximately 475 feet (145 meters) in length, was floated from the building dock and repositioned to the outfitting berth, Maersk reports. There, it will be fitted with its cranes, the largest of which will have a lifting capacity of 1,900 tonnes and the ability to reach up to 590 feet (180 meters) above the deck.

Maersk has highlighted in the past that the vessel would be capable of handling the largest offshore wind turbines. It will have 100 cabins and a walk-to-work gangway.

The installation vessel’s first assignment was for the Empire Wind offshore wind farm being developed by Equinor. The project was underway when the Trump administration, in mid-April, issued a stop-work order for offshore construction.
