The steel foundations for this project will be manufactured in Germany and Vietnam.
Installation work would start in 2016 and Jan De Nul is expecting to wrap up its job by 2017.

"Our newly acquired jack-up vessel, Vidar will install the 51 foundations working from the marshalling harbor in Ostend and the fall pipe vessel Simon Stevin will place scour protection on the seabed around the piles. Vidar will transport the turbines and blades from Denmark to install them up to 100m-high onto the foundations."
