The OCV is based on the Norwegian SALT 310 design and will measure 123 meters in length. It will feature a DP2 dynamic positioning system, a 150-ton active heave-compensated offshore crane, and a hangar for two work-class remotely operated vehicles (ROVs). The vessel will include a hybrid 1,000-kWh battery system and two 2,500-ton cable carousels. Accommodation for up to 123 personnel is planned, supporting extensive offshore operations.
Hugo Bouvy, Managing Director Offshore Energy at DEME, said: “With more than 5,000 km of subsea cables installed across wind farms in Europe and the United States, DEME continues to support clients in delivering offshore projects efficiently and reliably. Building on this track record, the new OCV further enhances DEME’s cable installation capabilities and expands its versatile fleet of vessels and solutions.”
The investment in the vessel is significant, valued between €50 million and €150 million. DEME’s order reflects its commitment to expanding offshore renewable energy capabilities and supporting subsea infrastructure projects in a sustainable and efficient manner.
PaxOcean confirmed earlier in 2025 that it had signed contracts for two OCVs with a major European shipowner, including options for two additional vessels. The new construction aligns with ongoing global demand for specialized vessels in offshore energy, particularly for wind farm and subsea cable projects.
The OCV will combine advanced automation, hybrid energy solutions, and versatile operational capabilities to support a broad range of offshore tasks, including cable installation, trenching, and maintenance. Its methanol-ready propulsion system offers flexibility for future low-carbon operations, complementing DEME’s sustainability strategy in offshore energy projects.
By adding the vessel to its fleet, DEME strengthens its operational capacity and positions itself to efficiently deliver complex offshore projects worldwide. The investment underscores the company’s focus on innovation, reliability, and long-term growth in the offshore construction and renewable energy sectors.
