Cathie and British Geological Survey score Scottish ground model contract

In: Windfarms

SSE Renewables has awarded Cathie and British Geological Survey (BGS) a contract to develop a ground model for the Front End Engineering Design (FEED) design of
Berwick Bank and Marr Bank (formerly Seagreen 2&3) offshore wind farms.

Cathie’s Newcastle based team will lead the project and work together with BGS geoscientists who are based at the Lyell Centre in Edinburgh, to provide a complete solution for the regional ground model, integrating geology, geophysics and geotechnics.

Located off the East coast of Scotland at the mouth of the Firth of Forth, the proposed site of the two wind farms is complex and has been subjected to multiple glaciations. Cathie and the British Geological Survey (BGS) have partnered together to develop a dynamic, regional ground model which will be used to mitigate seabed risk and to drive the engineering and development options for the projects. The geospatial nature of the modelling will provide an invaluable insight into the engineering geological hazards and conditions of the past that could have a bearing on the development.

Business Development Director for Cathie, Gareth Ellery said: “This collaboration between Cathie and BGS offers a unique combination of best-in-class understanding of the geological formation and shaping of the Firth of Forth Zone with specific understanding of the influence the geological context has on geotechnical engineering for offshore wind farm infrastructure, thanks to our 75GW experience of offshore wind projects worldwide and experience in the Seagreen zone”.

Dr Tracy Shimmield of the British Geological Survey and Director of the Lyell Centre, a partnership between BGS and Heriot-Watt University, said: “BGS is delighted to have been awarded this important contract jointly with Cathie. Our combined expertise in this area will ensure that that the wind farm project is a success structurally while also supporting the continued development of renewable energy in Scotland.”

Once complete, the proposed installed capacity of the
Berwick Bank and Marr Bank wind farms could be between 1400MW and 2300MW and 900MW and 1,850MW, respectively.
