Seaway 7 Seaway 7 is an offshore engineering and construction contractor specializing in offshore wind and subsea projects, headquartered in Oslo. The company provides installation, engineering, fabrication and project management services for renewable energy and oil and gas sectors and operates internationally across Europe, Asia Pacific, and the Americas. Seaway 7 is known for integrating heavy-lift vessels, flexible pipelines, and cable-laying capabilities to serve utility-scale projects such as array systems, export cables, and foundation installations.
Seaway 7 was formed amid consolidation in the offshore oil and gas and renewable energy sectors, combining assets and expertise from legacy firms with histories linked to Saipem, Subsea 7, Acergy, Technip, and McDermott International. The company's lineage includes projects associated with Statkraft, Ørsted, Equinor, Vattenfall, and RWE and draws on experience from field developments like Dogger Bank, Hornsea, Beatrice, Hywind, and Saga Fields. Expansion followed industry moves seen after the Global financial crisis of 2008–2009 and during the rapid growth following the Paris Agreement and European Energy Union policy shifts. Strategic partnerships and mergers mirrored transactions involving Aker Solutions, Boskalis, Van Oord, Allseas, and Jan De Nul Group as competition intensified for large-scale offshore renewables contracts. Corporate milestones also intersect with regulatory and commercial frameworks such as Borgarting Court of Appeal decisions, European Commission state aid guidelines, and procurement practices from operators like Centrica and Shell.

Projects often involve foundations such as monopiles, jackets, and floating concepts akin to Hywind Scotland and WindFloat Atlantic. The company has executed scopes including turbine installation, array cable lay, export cable burial, and offshore substation installation in partnerships with developers like Shell Renewables, EDF Renewables, BP, TotalEnergies, and EnBW. Commissioning and testing phases mirror practices used on assets tied to Centrica Storage Limited and Perenco field developments.
Health, safety and environmental management align with standards from ISO 45001, ISO 14001, and recommendations from bodies such as International Maritime Organization and Occupational Safety and Health Administration.
