As a main contractor, Van Oord transported and installed all 102 foundations. It is the largest number of three-legged wind turbine foundations ever installed offshore.
The jacket foundations and anchoring piles were manufactured at different locations; the UK, Spain and the Middle East. In order to be able to install wind turbine foundations at a depth of more than 40 metres at a location where the seas are often rough, the current strong and visibility minimal, Van Oord developed a pile-driving template. The template was used to drive the anchoring piles for each three-legged jacket foundation into the seabed with millimetre precision.
Due to be completed in 2020, East Anglia ONE is expected to supply the equivalent of more than 630,000 British households with green electricity. Source: Van Oord
