Project Introduction:

Jeonnam 1 is a 96-MW offshore wind farm located off the coast of Shinan County, Jeonnam Province in the southwest of Korea. Comprised of ten wind turbine generators (WTGs), Jeonnam 1 represents the country’s first commercial offshore wind farm.

The water depth at the site ranges from 5 to 20 metres, with monopile foundations featuring monopiles with diameters of up to 8.5m. The wind farm is scheduled to be operational in 2025.

ABL was appointed as the marine warranty surveyor (MWS) for the transportation and installation (T&I) for the foundations, export cable, inter array cable and wind turbine generator components. The scope of work included providing expert technical reviews, document approvals, vessel inspections and site attendances.

Having successfully completed the installation of the foundations and export/inter array cables, the installation of the first WTG was completed on September 30th 2024. Surveyors from ABL K orea and ABL Singapore attended on site to oversee the successful operation.
