The TWIN X-STERN solution translates to main propulsion units fore and aft, enabling the vessel to perform swift operations at manned and unmanned installations with low fuel consumption. Featuring hybrid battery propulsion and prepared for green methanol fuel, the vessel is designed to meet future environmental standards while ensuring excellent seakeeping and operational efficiency.

The hull was built at Crist in Poland, and the arrival at Ulstein Verft marks the start of the outfitting and commissioning phase, where advanced systems and equipment will be installed and tested before delivery in 2026.

The ship is a versatile platform for offshore wind and or offshore operations, including maintenance and construction support. With motion-compensated gangway and crane solutions, optimised logistics, and large storage capacities, the vessel is tailored for safe and efficient work in demanding offshore environments.
