Offshore Construction Start

The Ossian offshore wind farm, a large floating wind project located approximately 80 km south‑east of Aberdeen within an 859 km² site area, has an indicative programme that schedules the start of its offshore construction phase in the second quarter of 2031. Project documentation for the Array, which comprises up to 265 floating wind turbines with associated floating foundations, mooring and anchoring systems, fixed-bottom offshore substation platforms and inter-array/interconnector cables, states that commencement of the offshore construction phase, framed as site preparation activities, is expected in Q2 2031 and that construction will then continue through to late 2038. The same programme indicates that key construction activities such as floating turbine mooring and anchoring installation, OSP installation, cable installation and turbine installation/commissioning will be phased across this period rather than undertaken continuously. Supporting application material for the marine licences confirms that construction is due to commence in 2031 with an anticipated eight‑year construction period, while the Non‑Technical Summary to the Array EIA Report likewise explains that the Array construction phase is anticipated to commence in 2031 and last for up to 96 months. Taken together, these documents provide a consistent picture of a planned offshore construction start around Q2 2031, contingent on securing the necessary consents and completing pre‑construction activities such as surveys, sand wave and boulder clearance, and unexploded ordnance clearance within the project site boundary.
