Gavin and Doherty Geosolutions (GDG) is undertaking the concept foundation design for the first 200 MW of Phase 1 of the Phu Cuong Soc Trang offshore wind farm in Vietnam.

As part of the study, GDG said it had undertaken 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 200 MW development area.

The objective was to develop a site-specific monopile concept and to provide foundation weight estimations, taking into account the environmental and ground conditions, including extensive areas of coastal mudflat and unique metocean conditions.

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

The project development is being led by Mainstream Renewable Power in partnership with the Phu Cuong Group.

The first 200 MW of Phase 1 has received approval and is expected to become operational in 2023. It is expected to comprise between 29 and 45 turbines.
