Allseas has ordered two newbuild offshore construction vessels (OCVs). Contracts for the two methanol-ready vessels were signed on 9 April, with construction to take place at Wuchang Shipbuilding Industry Group in China.
Based on the proven SALT 308 OCV design, the vessels feature advanced equipment and systems to deliver enhanced performance, flexibility and functionality. The first vessel is scheduled for delivery in September 2026, with the second following in December 2026.
The new vessels boost Allseas’ construction and support capacity, enabling greater deployment flexibility and freeing up existing OCVs for larger, more complex scopes of work. With the investment Allseas wants to remain at the forefront of the growing offshore construction and subsea installation sectors.

Vessel capabilities
Each vessel will measure 100 metres in length, feature a 1100-m2 cargo deck and accommodate up to 110 personnel. Advanced features include:

- 150-tonne active heave-compensated offshore crane
- Hangar housing two work-class remotely operated vehicles (ROVs)
- Hybrid 1500-kWh battery energy storage system
- Methanol-ready propulsion design for future fuel flexibility.
- Designed with maximum operational versatility in mind, the vessels are ideally suited for subsea construction, ROV support, and inspection, maintenance and repair activities.

Expanding versatility
Dries van Strijp, Allseas’ Vice President Operations, explains that the decision to acquire two newbuild vessels follows a thorough evaluation of all options to expand the fleet’s versatility and meet future market demand.
‘We recognised a clear need to optimise our vessel deployment to support an increasingly diverse and complex project portfolio,’ says Van Strijp. ‘After carefully exploring all available options, it became clear that securing two next-generation newbuilds – fully optimised with the latest technology – was the best long-term solution to strengthen our capabilities and capture new opportunities in a growing offshore market.’
