The newbuild is of VARD 407 design which has been tailored to meet EnBW’s specific requirements. North Star has contracted India’s Cochin Shipyard to build the ship bound for EnBW.

“He Dreiht is currently one of Europe’s largest energy transition projects and once operational, will supply green power to 1.1million homes. Following the highly regulated EU tendering process, we are thrilled to be selected by EnBW as part of their maintenance solution to ensure once completed, the wind farm remains consistently operational and generating renewable electricity,” said Caspar Blum, North Star European renewables lead.

The vessel will feature the Voith Schneider eVSP propulsion system and will be prepared for the use of methanol as a fuel. The SOV will also be fully equipped with a height-adjustable motion-compensated gangway and 3D compensated crane.

“This vessel will be the backbone of our service and logistics operations at our He Dreiht wind farm. Working with North Star, we were able to specify its setup to ideally meet the requirements of our operations teams. Its innovative, methanol-based propulsion system helps us to further decarbonise our industry’s operations,” said Michael Splett, Global Head of O&M Wind Offshore at EnBW.

Scheduled to commence long-term charter with EnBW from the end of next year, the SOV will provide accommodation for up to 34 wind technicians as they maintain the project’s 64 V236-15.0 MW wind turbines provided by Vestas. The ship will also act as a logistics hub and warehouse.

The agreement marks the firm’s first offshore wind win outside the UK market, a milestone step in its European growth strategy to add 40 new SOVs to its fleet by 2040.
