First foundation installed on Thornton Bank 2Projects and Operations // July 1, 2011
The first foundation of the Thornton Bank 2 offshore windfarm has been installed off the coast of Belgium.
The 50m high, 550 tonne foundation (a so-called jacket foundation) was manufactured in Hoboken near Antwerp and transported via pontoons through the Scheldt estuary to its final destination around 30km off the Belgian coast.
Using a heavy duty crane, the foundation was then placed on top of the foundation piles that were already installed on the seabed and attached to them.
This summer, all 25 foundations of the secondn phase of Thornton Bank will be installed in water depths ranging from 12m to 25m.
“We are well on schedule with the Thornton Bank project. The logistics chain is working extremely well and it allowed us to complete the preparations of the underwater construction site and the positioning of the foundation piles in the past few weeks as planned. Unless the weather thwarts our plans, the coming weeks and months will not only see the completion of the foundation work but also the wiring for the wind turbines and for the offshore substation”, said Martin Skiba, head of Offshore Wind Power at RWE Innogy.
