Ship history

The vessel, which utilises the TWIN X-STERN design, features two sterns and main propellers fore and aft, making it an ideal choice for Dynamic Positioning (DP) operations. With the TWIN X-STERN solution, these ships can achieve improved fuel efficiency while also minimising motion, a crucial element for safety, as the technicians need high-quality rest to perform their duties.

The vessel has a length of 89.6 m and a beam of 19.2 m. It 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 5-tonne offshore cargo lifts is installed. The optimised onboard logistics include large storage capacities and a stepless approach to the offshore installations.

The SX222 design platform is adapted to the shipowner's needs, including 111 cabins, including 90 single cabins. In total, the vessels can accommodate 132 people. The ships are flexible and well-suited for work in areas such as O&M (Operations and Maintenance) or construction support, especially in challenging weather and sea conditions.
