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.
As offshore oil and gas developments become more complex, operators are rethinking how fields are designed, operated, and supported. For Aker BP, this shift is clearly visible in the Yggdrasil development, the largest ongoing project on the Norwegian Continental Shelf.
Ulstein Power & Control has signed a contract to deliver complete hybrid power and automation systems for two cable-laying vessels to be built for OMS Group at Ulstein Verft. “This is an important contract for us and confirms our position as a leading supplier of systems for complex maritime operations,” says Peter Pilskog, Managing Director of Ulstein Power & Control.
An expedition cruise takes you to the edges of the world, places that remain wild, remote and profoundly beautiful. As exploration gives way to evening, the transition back to the ship feels seamless, from raw landscapes to effortless luxury.
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.
For Norway, the relationship with the sea is so fundamental that it is reflected even in the country’s currency. For centuries, people have relied on the sea, not for conquest or adventure, but for survival, transport and connection. Long before the age of the Vikings, boats were already an essential part of everyday life, shaped by the need to operate safely and reliably in open, often unforgiving waters. Rock carvings and archaeological finds show that early vessels were carefully adapted to their environment, evolving over generations through experience rather than ambition.
When the expedition cruise vessel, 'Greg Mortimer', entered service in 2019, she marked a turning point for the industry. Today, several years and countless voyages later, she stands as a proven reference for a new generation of expedition cruise ships.
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.
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.
