Seaway7 has completed the final inner-array cable installation at the 1.4 gigawatt East Anglia THREE offshore wind farm, MarineLink Maritime News reported on 27 October 2026.
The work closes a significant phase of offshore construction for the project, which is being developed by ScottishPower Renewables in partnership with Masdar. The item on MarineLink identified Seaway7 as part of the Subsea7 Group.
MarineLink described the completion as the final inner-array cable lay, a task that connects the windfarm's offshore electrical infrastructure. The report framed the achievement as another milestone in the wider programme of offshore works for East Anglia THREE.
Project milestone
Completion of the inner-array cable installation indicates the project has passed an important construction stage, MarineLink noted. The developer partnership of ScottishPower Renewables and Masdar remains the named sponsor for the 1.4GW scheme.
Contractor role
Seaway7, operating within Subsea7 Group, was credited with finishing the inner-array scope in the MarineLink item. The report positioned the completion as a step within the sequence of offshore construction activities for the windfarm.
MarineLink's account did not set out further operational or commissioning dates for East Anglia THREE. The report presented the cable installation finish as a discrete event rather than linking it to subsequent onshore or grid milestones.
The news item forms part of ongoing coverage of the East Anglia THREE development and of Subsea7 Group's offshore installation portfolio. MarineLink provided the details on 27 October 2026 and is the source of the reported completion.
