Offshore Construction Start

Offshore construction for the Erebus floating offshore wind project in the Celtic Sea is planned to commence in 2026. The project’s Environmental Statement for Chapter 10 (Fish and Shellfish Ecology) explains that construction of the offshore elements is estimated to last eight months between 2026 and 2027, indicating that the offshore construction campaign will begin during 2026 and continue into the following year. This construction window is used in the cumulative effects assessment alongside nearby marine projects, reflecting how Erebus’s offshore works will overlap in time and space with other activities in the area. The official Erebus project page from Blue Gem Wind reinforces this timing, stating that the project will become one of the largest floating offshore wind projects in the world when constructed in 2026. Taken together, these sources show the developer’s intention to initiate the main offshore construction phase in 2026, aligned with the project’s role as a 100 MW test and demonstration scheme in the Celtic Sea. The projected eight‑month programme suggests a relatively concentrated offshore campaign, after which the project would transition toward commissioning and operations. As of the information presented, this milestone remains a planned future event rather than one that has already occurred.
