Five 9.5MW MHI Vestas turbines will be mounted on the platforms, according to project developer Kincardine Offshore Wind Limited (KOWL), which is majority-owned by Spanish construction company Cobra Wind International.
Windar is to start construction of the platforms with plate cutting and forming at its facilities in Avilés, northern Spain, in May 2019.
Fabrication of the remaining components and assembly of the units will then take place at Navantia’s shipyard in Fene, also in northern Spain.
Production is due to be concluded in April 2020, the two companies stated.
In total, about 1,250,000 man-hours are expected for the production process, which will use about 15,000 tonnes of steel, Navantia stated.
The Navantia-Windar joint venture has already installed five spar-type units at Equinor’s Hywind project off of Scotland and one semi-submersible design at Windplus’ Windfloat Atlantic project off of Portugal.
The Kincardine demonstration achieved first power in October 2018, when a 2MW Vestas turbine was commissioned at the site.
