Explore our portfolio of subsea support vessel designs.
Subsea support vessels encompass a variety of specialised ships designed to support various operations related to subsea construction, maintenance, and exploration. These vessels are tailored for specific tasks and environments in the offshore energy industry.
Our designs give high functionality, large work deck and equipment-carrying capability and good seakeeping abilities to ensure high operability under harsh weather conditions, high transit speed and low fuel consumption.
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.
The expected global gap in vessel capacity for foundation installation and transportation for ever-growing offshore wind components can slow down the growth speed of offshore wind farm developments across the globe.
We accept the design challenge.
In the vast expanse of offshore wind energy, cable-laying vessels are essential—the silent architects of our renewable future. As wind farms grow larger and more ambitious, the demand for efficient cable installations has intensified. Enter the ULSTEIN SX225, a vessel designed to tackle the challenges head-on.
Offshore wind energy generation is one means to reach international climate goals. Ulstein has developed offshore wind designs since 2006. The designs draw on our broad experience in oil and gas, and range from new turbine installation concepts to foundation installation vessels and service operation vessels.
Against the backdrop of the Shanghai Electric wind farm, the Ulstein-designed vessel underwent thorough scrutiny.
On 4 April 2024, the keel laying ceremony took place for the DP3 cable laying vessel (CLV) Nexans Electra. This vessel will transport and lay various types of subsea cables, including cable bundles, as well as handle recovery and repair operations for Nexans Marine Operations AS in Norway.
On Saturday, 6 April, the CSOV Olympic Boreas was launched from the dock hall at Ulstein Verft, Norway. The vessel is based on the novel TWIN X-STERN solution, a '4-wheel-drive' solution for the seas.
Aurora Expeditions, the Australian-owned expedition travel company, will soon welcome its third purpose-built small expedition ship, Douglas Mawson, to its family of pioneering vessels. The cruise vessel, based on the ULSTEIN CX103 design, is due to begin sailing in December 2025.
The offshore energy market is booming, and so is the demand for subsea vessels that can operate in challenging environments and perform complex tasks. Whether installing, maintaining, or decommissioning offshore wind farms or oil and gas platforms, subsea vessels need to be flexible, efficient, and reliable.
Ulstein Verft will convert the fish feed carrier Eidsvaag Pioner with a modern feed discharge system. This is a large and comprehensive project. A large part of the scope will mainly affect the steel and outfitting department but during its stay the project will at some point engage all the departments in Ulstein Verft.
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.
