Yno 320 launch: A new era for BS Offshore and Ulstein Verft
On Monday, 24 February 2025, BS Offshore and Ulstein Verft passed a significant milestone with the launch of the Yno 320, a state-of-the-art Commissioning Service Operation Vessel (CSOV).
This event followed an extensive outfitting phase that included the installation of electrical and mechanical systems, piping, accommodation, and system integration.
The Yno 320 was towed from Ulstein Verft’s dock hall to the outer dock on 20 February. While stationed in the outer dock, the Ampelmann tower and gangway were installed. On 23 February, the vessel was taken into the sea and positioned quayside, where she will remain until sea trials commence later this year.
Featuring the innovative TWIN X-STERN design, the Yno 320 is equipped with advanced technology, such as a 3D-compensated crane and a Walk-to-Work gangway, ensuring safe and efficient personnel and cargo transfer to offshore wind turbine facilities. Its diesel-electric propulsion system and substantial battery energy storage significantly reduce its environmental footprint and prepare it for methanol as fuel.
The launch of this CSOV newbuild marks a leap forward in supporting the offshore wind industry. The vessel offers modern, high-comfort accommodation for up to 132 crew and clients. The vessel is planned for delivery in Q2 2025, enhancing BS Offshore's operational capabilities.
