N-Sea Group has entered into a long-term charter agreement with Rederij Groen for the newbuild offshore support vessel Dominus, as the company expands its fleet and subsea activities.
The vessel is being built by PASSER at Shipyard De Hoop in Tolkamer, the Netherlands, with delivery scheduled for April 2027.
The keel laying took place in the final week of February, marking the start of full construction. According to the project details, Dominus will have an overall length of 69.85 m, a beam of 15.77 m and a draught of 4.50 m.
The vessel is being designed to support geophysical and subsea survey work, including 2D and 3D seismic surveys and wide swath UXO surveys. It will also feature a midship moonpool, lifting capacity and a dedicated deck arrangement aimed at expanding geotechnical capabilities and supporting integrated site investigation work.
Dominus will be equipped with Tier 3 engines and diesel-electric propulsion. The design also includes attention to crew safety and well-being.
For N-Sea Group, the charter supports its strategy of operating dedicated vessels under full management and control. The company said this approach supports integrated teams and contributes to safe, predictable and high-quality project execution.
The addition of Dominus follows the scheduled arrival of survey vessel Geo Master in April 2026 and cable installation and repair vessel Altera in June 2026.
