Ulstein has been active in the offshore wind market since 2006. We develop solutions to support all stages in the life of offshore wind farms, from planning and development, installation and commissioning, operations and maintenance, through to repowering and decommissioning.
Cable laying vessel designs for telecom, infield, power cables and umbilical.
Subsea rock installation vessel, suitable for installation of a wide range of rock sizes through a fallpipe in the moonpool, through a fallpipe over the side or through a tremie pipe over the side. With a DW of 14,000t, a length of 154 m and a beam of 28 m, the vessel can operate in depths of more than 600 metres.
A dynamically-positioned, 48,000 DWT heavy lift transport and installation vessel for the offshore wind industry. The design combines the benefits of a semi-submersible transport vessel with a large, 3,000 mt lifting capacity main crane. Can perform heavy lift crane operations with the main deck submerged.
Service operation vessels (SOV), Construction Support Vessels (CSV/CSOV) and Installation Support Vessels (ISV) are reliable Walk-To-Work platforms for wind farm support operations.
Ulstein's second hydrogen hybrid design for the offshore wind industry, the ULSTEIN J102 zero emission wind turbine installation vessel (WTIV), can operate 75% of the time in zero emission mode. Using readily available technology, the additional cost is limited to less than 5% of the total CAPEX.
Hydrogen is considered as the ultimate zero-emission solution. Ulstein's vision is to create tomorrow’s solutions for sustainable marine operations, and our first hydrogen powered ship design is now market-ready, offering zero-emission marine operations. The solution can be taken in use today.
Offshore wind is growing, but with margins under pressure it is also challenging. Current demand reveals a shortage of heavy lift vessels. The key questions are: how should the new generation crane ships look like? What are the trends? And where is the ‘sweet spot’ to invest in?
Investing in offshore wind
With the dawn of the new 12MW offshore wind turbines, installation capacities of the current, third generation wind turbine installation vessels will be pushed to the limits and beyond. A new generation of jack-up vessels is necessary to serve the future offshore wind industry.
Acta Auriga was contracted to work at the offshore wind farm BARD Offshore 1: “Ocean Breeze Energy decided on this vessel due to a favourable combination of capability, capacity, design and fuel consumption. The delivery precision from Ulstein was also important.”
Subsea rock installation (SRI) vessels are widely used in the offshore industry, stabilising and protecting subsea pipelines, cables and other structures at the sea bed. For the offshore wind industry, SRI vessels also lay protective coverings of rock around turbine foundations, to avoid scouring.

Offshore wind references
ULSTEIN has been developing 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 and service operation vessels.
Wide range of designs
Offshore Wind Farms are being established further from shore. At some point, overnight stays for the service technicians become necessary, and the transport normally done by Crew Transfer Vessels must be replaced by other transport tools. SOVs are becoming the new standard.
The shipping industry is transitioning towards reduced emissions and improved energy efficiency. Whether integrated in a novel design, or retrofitted, a solution supporting the transition should be the best compromise between operational needs, forming a good balance between cost and benefit.
The offshore wind market is an abundant source of renewable energy. To reach international climate goals, major markets around the world have set goals to increase their percentage of renewable sources in their domestic electricity consumption. Consequently, many offshore wind farms are currently being established.
