Service operation vessels (SOV/CSOV)
Innovative vessel designs for offshore wind logistics
Explore our portfolio of Construction Service and Service Operation Vessel designs.
Designed for performance in offshore wind and oil & gas operations
Ulstein’s service operation vessels (SOVs and CSOVs) are purpose-built to support the full lifecycle of offshore wind farms and energy infrastructure. Whether it’s wind farm maintenance, cable installation support, or safe and efficient crew transfer, our vessels are engineered to deliver reliable performance in demanding marine environments.
Operators benefit from reduced fuel consumption, enhanced operability, and improved safety—especially in harsh weather conditions. Our designs prioritise crew comfort, operational uptime, and environmental responsibility.
Key innovations include the patented X-BOW® and TWIN X-STERN® hull forms, which reduce slamming and improve seakeeping, as well as hybrid propulsion systems that lower emissions and fuel costs. Our vessels are available with either DP2 or DP3 dynamic positioning systems, depending on the configuration, to ensure precise station-keeping during walk-to-work operations.

Cutting-edge solutions that optimise vessel performance and enhance operational efficiency.
