HAMBURG, Germany  Bernhard Schulte Offshore (BS Offshore) has commissioned Ulstein Verft to build two commissioning service operation vessels (CSOVs) of the ULSTEIN SX222 design, with options for four further vessels.

The TWIN X-STERN design provides two sterns and main propellers both fore and aft to support DP operations whatever the direction of the weather, and without speed restrictions on speed. The solution is also said to deliver improved fuel efficiency while minimizing motion.

BS Offshore previously awarded Ulstein Verft newbuild contracts in 2015 and later in 2018, completing the upgrade of the Windea Leibniz earlier this year. The newly ordered ships should be delivered in 2025.

Both will have a large, centrally positioned walk-to-work motion-compensated gangway and elevator tower for personnel/cargo transfers, and a 3D-compensated crane capable of 5-t offshore cargo lifts.

Optimized onboard logistics will include large storage capacities and a step-less approach to the offshore installations.

The vessels will have a length of 89.6 m, a beam of 19.2 m and single cabins for 110 persons (with accommodation for a total of 132 people). They will have hybrid battery propulsion and will also be prepared for methanol fuel for future carbon-neutral operations.

Both will be sited to operation and maintenance and construction support, including in harsh weather and sea conditions.
