Gavin and Doherty Geosolutions Ltd. (GDG) was commissioned to undertake concept foundation design for the first 200MW of Phase 1 of the Phu Cuong Soc Trang offshore wind farm.

The project development is being led by Mainstream Renewable Power in partnership with the Phu Cuong Group. Once all phases are operational, the project is expected to provide power to more than 1.2 million homes. The first 200 MW of Phase 1 of the wind farm has already received approval and is expected to become operational in 2023.

As part of the study, GDG undertook an initial foundation screening and option assessment, followed by a more detailed analysis and design of the preferred foundation concept. This study included geotechnical interpretation of recently acquired borehole and CPT data and foundation design for representative monopile foundations within the First 200MW Development Area. The objective of the study was to develop a site specific monopile concept and to provide foundation weight estimations, taking into account the environmental and ground conditions at the site, including extensive areas of coastal mudflat and unique metocean conditions.

The outcome of the study was used to inform the Capital Expenditure (CAPEX) estimation by the developer and supports the tender documents that were issued to select turbine suppliers and balance of plant contractors in October 2020.
