Norway pioneers new solutions in offshore wind farm construction
Page date: published 5 December 2024; updated 30 September 2026; 5 min read (as rendered).
The article surveys Norwegian suppliers in offshore wind construction. It describes Ulstein’s hydrogen-hybrid SX190 construction support vessel, which the page says can operate in dynamic positioning mode for up to five days on hydrogen, and its J102 turbine installation vessel, designed for zero-emission operation during 75% of working time while jacked up. Kongsberg Maritime supplies integrated positioning, propulsion, energy control and sensor systems for installation vessels. These specifications are presented as company/page claims.
For grid connections, the article names Nexans Norway as a subsea cable and cable-laying supplier, including the Nexans Aurora vessel, and Seaway7 as a cable installation contractor on Polish projects MFW Bałtyk II and III. It describes Aibel and Hitachi Energy’s substations for Dogger Bank A, B and C, plus their Ocean Grid work on an HVDC platform. Aker Solutions and partners are developing a subsea substation for floating wind; the page cites a potential 20–50% capital-cost reduction. HydePoint is developing a combined offshore substation and hydrogen production unit.
Port infrastructure and bundled installation services are also discussed. Citing a North Sea Basin study, the page says assembly and installation port capacity would need to double by 2030 and that Norwegian ports could play a role. Axess bundles cable installation, inspection and maintenance services; DOF is described as providing assembly, installation, cable laying and maintenance with its own vessel fleet. The report link on the page offers a copy of the North Sea Basin analysis.
Several dates and project-status claims are historical or forward-looking; check current project updates independently.
