Crowley and ESVAGT’s US joint venture CREST has chosen HAV Design to develop a newbuild service operation vessel (SOV) destined for the Coastal Virginia Offshore Wind project. The contract marks a US breakthrough for HAV Design, which becomes the first European ship designer to develop an SOV for the US market.

The newbuild hybrid vessel will be HAV 832 SOV design and will be constructed by Fincantieri Bay Shipbuilding in Sturgeon Bay, Wisconsin. HAV Design’s contract is with Fincantieri Bay Shipbuilding. The ABS-class vessel will be 88 metres long and 17.6 metres wide, capable of carrying 20 crew and 60 special personnel and sail under US flag. The ship is predicted to go into service in 2026.

Consistent with the requirements of the Jones Act, Crest will be the Owner of the vessel, Crowley will operate the SOV with U.S mariners, while ESVAGT will provide technical advice on the design, construction, and operation of these vessels.

“We have designed and developed numerous SOVs for use in demanding offshore climates, but this is the first time we are designing a vessel for the US market. We are confident in the operational benefits our vessel design brings to the table, so we believe that this contract can open the door for further work in the USA,” says Gisle Vinjevoll Thrane, vice president of sales at HAV Design.

Following completion, the newbuild SOV will go on charter for Dominion Energy for its massive 2.6 GW Coastal Virginia Offshore Wind Project. This will include 176 wind turbine generators provided by Siemens Gamesea. Once online, the project is expected to provide enough energy to power up to 660,000 homes.
