Siemens has released a video showing what level of precision was needed to install 48 foundation posts at the 144MW Westermeerwind offshore wind farm, situated in the Ijsselmeer, an artificial lake in the central Netherlands.
Siemens installed the first monopile foundation in March 2015, and proceeded to install the remaining 47 throughout April and May.
The 35-meter long foundation piles, weighing around 250 tons, were transported from Vlissingen to the project site, 500 meters from the Noordermeer Dijk.
The wind farm produced its first electricity from 17 Siemens 3MW turbines installed at the time back in November 2015.
The Westermeerwind is expected to be fully completed by February 2016.
