Offshore Construction Start

The MarramWind Environmental Impact Assessment (EIA) Report, Volume 1 Chapter 4, sets out the project’s construction programme and confirms that construction of the project is anticipated to commence in 2030. This chapter describes the offshore wind farm and associated onshore and offshore infrastructure, and explains that the overall duration of construction of the offshore infrastructure could be up to 12 years, with a shorter period of up to nine years for the onshore works. The project will be delivered in phases, and an Outline Construction Traffic Management Plan and other construction methodologies will be developed prior to works starting, including arrangements for construction workforce and logistics. Within this context, the statement that “construction of the Project would commence in 2030” is presented as the indicative starting point for the main build programme, including offshore activities at the project site. [1] Earlier consultation materials prepared by the developers described a broader window, noting that construction works were anticipated to commence in the late 2020s, subject to consent, and that, if consented, construction was expected to begin in the early 2030s, with phased delivery due to the project’s scale. These materials underline that the programme is contingent on achieving the necessary consents and reflect an expectation that there will be a substantial multi‑year offshore construction campaign. Taken together, these sources indicate that offshore construction at the MarramWind site is planned to start around 2030, in line with the more specific timing now set out in the December 2025 EIA.
