Once a boat landing had been fitted to a pile, it was followed by the installation of a “transition piece”, which forms a base upon which the wind turbine stands. A crane affixed to the deck of a jack-up barge lowered the transition piece over the upper section of each pile, so that it slots over the top of the foundation like a sleeve. The transition piece was then fully secured in position using an industrial grout.

The transportation and installation of the transition pieces was carried out using the jack-up barge “Wind”.The transition pieces, which are painted bright yellow for visibility, were pre-fitted with an external ladder, a top access platform and two intermediate rest platforms, which assists maintenance personnel in accessing the wind turbines.
