Explore our portfolio of Construction Service and Service Operation Vessel designs.
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.
Turning visions into realities motivates us to keep pushing for progress in the maritime industry.
You can learn more about how we work with our customers to achieve their visions through our stories.
Faster delivery, lower emissions and reduced costs - the subsea sector is now expected to achieve all three simultaneously. At the OSJ Subsea Conference 2026, Ulstein’s Chief Designer, Øyvind Gjerde Kamsvåg, outlined how repurposing can meet these demands and, in many cases, outperform newbuild strategies.
Ulstein Verft's yard number 322, the CSOV Genesis Sea, is about to conclude a successful sea trial, a major milestone in the newbuild project.
Norway’s maritime sector is experiencing one of its strongest periods in decades, driven by national growth and the exceptional performance of the Møre og Romsdal cluster, home to Ulstein and many leading companies.
OMS Group, a leading provider of subsea digital infrastructure, has signed contracts with Ulstein, a world-renowned designer and builder of advanced offshore vessels, for the design and construction of two cable-laying vessels.
What made a seasoned veteran, a newly qualified engineer and an eager apprentice choose Ulstein – and how do they see the future? Step into the everyday working lives of Adolf, Nicholine and Jonas, and gain an insight into a workplace in constant development, spanning everything from the very first working day to more than fifty years in the same company.
At Ulstein Verft, the new year began with launching, lifting operations and docking of two offshore wind newbuilds.
On 5 January 2026, Acta Pegasus was delivered by Tersan Shipyard to Acta Marine. This vessel is the first of four newbuild Walk-to-Work (W2W) Construction Service Operation Vessels (CSOVs) designed by Ulstein Design & Solutions AS for Acta Marine.
When expedition cruise vessels need urgent support at the edge of the world, Ulstein Power & Control delivers. Recently, Automation Engineer Markus Myklebust Myrstad travelled solo to Ushuaia, Argentina – the southernmost city on Earth – to ensure two ships stayed operational and ready for their next adventures.
Telecommunications is no longer just a convenience; it is becoming the backbone of modern society. Secure and resilient communication networks are increasingly regarded as critical national infrastructure, sometimes even more vital than traditional energy resources. This shift reflects a world where data flow underpins everything from economic stability to military readiness.
We will be attending many events and conferences, which can be an excellent opportunity to meet. See if we are participating in any upcoming events you are going to.
