Offshore Construction Vessels

Designed with maximum operational versatility in mind, the vessels are ideally suited for subsea construction, ROV support, and inspection, maintenance and repair activities. 

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. 

The first vessel is scheduled for delivery Q4 2026, with the second following Q1 2027. This investment ensures Allseas remains at the forefront of the growing offshore construction and subsea installation sectors. 

Cutting-edge capabilities for a dynamic market

Each vessel will measure 100 metres in length, feature a 1,100 m² cargo deck and accommodate up to 110 personnel. Advanced features include: 

• DP2 dynamic positioning system
• 150-tonne active heave-compensated offshore crane
• Hangar housing two work-class ROVs
• Hybrid 1,500-kWh battery energy storage system
• Methanol-ready propulsion design for future fuel flexibility.
