MHI Vestas’ V164-8MW turbine was installed on 9 April. It has had its power rating boosted to 8.8MW through the use of internal power modes, Vattenfall stated.
Two of the 11 turbines due to be installed at the EOWDC have been uprated to 8.8MW, while the other nine will have their capacities boosted to 8.4MW, the developer added.
The further uprating of two turbines boosts the site’s total capacity to 93.2MW, up from the originally planned 92.4MW.
Each turbine has a tip height of 191 metres and each blade is 80 metres long.
The turbines are being transported from Esbjerg on the west coast of Denmark aboard Swire Blue Ocean’s Pacific Orca vessel, and then installed from the same boat.
Yesterday’s turbine installation comes two weeks after the first suction-bucket jacket foundation was installed at the site.
Boskalis’ 25,000-tonne Asian Hercules III vessel took 15 hours to install the 1,800-tonne structure, Vattenfall stated.
The £300 million (€343 million) EOWDC site is the first to use the foundations for turbines on a commercial scale.
When completed later this year, the 93.2MW project will be Scotland’s largest offshore test and demonstration facility.
Its 11 turbines will be connected to the shore via a 66kV cabling system.
The EOWDC suffered a series of setbacks, mostly due to legal challenges by Donald Trump, which caused two years of delays. The project will be visible from one of Trump’s golf courses.
