With the arrival of hull number 323 on December 6, 2025, Ulstein Verft Shipyard has entered a critical stage in the construction of its next Commissioning Service Operation Vessel (CSOV). This unit, based on the SX222 platform, is the tenth vessel of TWIN X-STERN design to be developed by the company since 2022.
CSOV SX222 technology for efficiency and sustainability
This vessel integrates technical solutions to improve its maneuverability and energy consumption. Thanks to the TWIN X-STERNsystem, which incorporates propulsion at both ends, it can operate efficiently in both manned and unmanned installations.
In addition, a hybrid system with batteries and the capacity to operate with ecological methanol make it a platform prepared for future environmental regulations.
International construction with a Norwegian vision
The hull, built by the Crist shipyard in Poland, has been transferred to Norway for final outfitting. In this phase, complex systems such as counterbalanced cranes, dynamic access gangways and advanced logistical solutions.
The entire process is scheduled to be completed prior to official handover in 2026.
Modular design for demanding offshore operations
The new CSOV is designed to operate in highly complex offshore wind environments. Its capabilities include maintenance support, component logistics and assistance to offshore wind farm construction. offshore wind farm construction.
With large storage spaces and optimized systems, the vessel aims to offer operational reliability even in adverse conditions.
Sustained commitment to naval innovation
Ulstein, a family-owned and operated company with a history in ship design and shipbuilding, reaffirms with thisreaffirms with this project its long-term strategy in the offshore market.
This tenth vessel with design SX222 consolidates the adoption of green technologies and designs aimed at improving offshore performance and reducing the environmental footprint.
