We were thrilled to be part of Ireland’s developing offshore wind programme, marking our first direct involvement in an Irish offshore wind project. Commissioned by Fuinneamh Sceirde Teoranta, a joint venture between Corio Generation and Ontario Teachers’ Pension Plan, we conducted a benthic characterisation survey for the proposed Sceirde Rocks Offshore Windfarm. Located in the north-east Atlantic Ocean, this ground-breaking project is expected to be the first commercial-scale offshore windfarm on Ireland’s west coast, with an expected maximum export capacity of 450 MW.

The survey required a highly responsive approach, so we utilised multiple vessels to meet tight deadlines and navigate challenging weather conditions. Our team delivered expert and adaptive support to ensure the project’s success.

Key survey elements:

  • Drop-down camera surveys to visually assess seabed habitats.
  • Sediment grab sampling to characterise habitats and infaunal and epifaunal communities.

The survey established a comprehensive baseline dataset of habitats and biological communities and developed marine sediment and water quality baselines across the survey area to inform environmental impact assessment.

We are proud to contribute to this landmark renewable energy project, supporting Ireland’s clean energy transition and playing a pivotal role in advancing its offshore wind sector.
