Wind farm offshore support vessel TBN II

A TWIN X-STERN Commissioning Service Operation Vessel (CSOV), equipped with a hybrid battery propulsion system and prepared for green methanol fuel to enable carbon-neutral operations. The vessel features Ulstein's TWIN X-STERN design with two sterns and main propellers fore and aft. This bi-symmetrical configuration makes the vessel exceptionally well-suited for Dynamic Positioning (DP) operations. By enabling efficient manoeuvring in either direction and reducing unnecessary turns, the TWIN X-STERN solution enhances fuel efficiency while significantly minimising vessel motion, an important factor for safety and crew well-being, as technicians rely on high‑quality rest to perform their duties effectively. The vessel measures 89.6 m in length and 19.2 m in beam. She has a large, centrally positioned walk-to-work motion-compensated gangway and elevator tower for personnel and cargo transfers. Furthermore, a 3D-compensated crane capable of lifting 5-tonne offshore cargo has been installed. The optimised onboard logistics include large storage capacities and a stepless approach to the offshore installations. The ULSTEIN SX222 design platform has been adapted to the shipowner's needs, including 111 cabins, of which 90 are single cabins. In total, the vessel can accommodate 132 people. The ship is a flexible and attractive platform for work in areas such as O&M (Operations and Maintenance) and construction support, especially in challenging weather and sea conditions.
