Olympic's latest CSOV, the 'Olympic Notos', has been operational for six months since her delivery, and the feedback is outstanding.

Subsea rock installation is essential for offshore projects, and for over twenty years, Ulstein Design & Solutions BV has been leading the way in vessel design.

In today's evolving maritime industry, ship owners encounter challenges and opportunities. What options do you have when markets are unpredictable? Sometimes it's all about striking that perfect balance.

"When a viral Drake Passage video surfaced showing huge swells crashing over the bow of Quark Expeditions' Ocean Explorer, it wasn't just the power of the Southern Ocean that made waves. 
The real star? The ship's cutting-edge X-BOW design."

Oslo, 26 March 2025: At the Undersea Defence Technology conference, thyssenkrupp Marine Systems and Ulstein Verft signed a Letter of Intent to collaborate on delivering the Royal Norwegian Navy's next advanced frigates.

In February 2025, Ulstein introduced the innovative SX250 design, a vessel specifically engineered to excel in wave heights up to 2 metres Hs. This strategic design choice aligns perfectly with real-world operational data, revealing that 94.2% of walk-to-work (w2w) operations occur in conditions with wave heights below 2 metres. 

In the competitive world of cruise ship ownership, making smart investments is crucial. Ulstein's innovative cruise ship designs offer unparalleled value, combining efficiency, safety, and sustainability. Here's nine reasons why investing in Ulstein's cruise vessels benefit ship owners, operators and passengers.

On 11 March 2025, the hull of yard number (Yno) 321 for BS Offshore arrived at Ulstein Verft. This marks the beginning of a new phase in the shipbuilding process. The vessel is designed by Ulstein Design & Solutions AS for ‘walk-to-work’ (W2W) operations, where personnel walks via a motion-compensated gangway from the ship to a wind turbine.

BS Offshore and Ulstein Verft has passed a significant milestone with the launch of the Yno 320, a state-of-the-art Commissioning Service Operation Vessel (CSOV). 

The Anchor Handling Tug Supply Vessel (AHTS) "Odin Viking" arrived at Ulstein Verft on 1 February 2025 to install a brand-new Launch & Recovery system (L-LARS) from Evotec, a supplier based in Ulsteinvik. The vessel were once again ready for new adventures on 30 March, after going through extensive installations and maintenance in a flexible project.

Offshore wind farms are currently serviced using Crew Transfer Vessels (CTVs) or helicopters for day operations, and Service Operation Vessels (SOVs) for extended periods. What if there were a CAPEX-smart design that reduces building costs by over 50% compared to an SOV and supplement the SOVs on most tasks? 

Penta-Ocean Construction, a prominent Japanese general contractor, has commissioned Ulstein Design & Solutions B.V. to design its new heavy lift vessel for offshore wind foundation installation. The customised ULSTEIN HX118 design will feature a 5,000-ton Huisman main crane and the ULSTEIN U-STERN™, which enables the installation of increasingly larger monopile foundations.

In a landmark deal, Ulstein Design & Solutions AS has secured its largest aftermarket design contract to date for the cable-laying vessel Orient Adventurer. The contract, awarded by Dong Fang Offshore (DFO), involves both basic design and engineering provided by several of the companies in Ulstein. 

In close collaboration with Heerema, Ulstein Design & Solutions BV has provided engineering services for integrating the innovative motion-compensated gripper frame (MCGF) on Heerema Marine Contractors’ ‘SSCV Thialf’. This technology is key to efficiently installing large monopiles for offshore wind farms, driving progress in the renewable energy sector. The semi-submersible crane vessel is essential in advancing offshore wind technology, aiding the construction of future wind farms essential for the global energy transition.

Four state-of-the-art TWIN X-STERN CSOV vessels for Acta Marine, are currently in various phases of construction at the Tersan Shipyard, Türkiye. The vessels are designed by Ulstein Design & Solutions AS.
