The demand for expected and unexpected maintenance work increases with every newly installed offshore wind turbine. With a potential of more than 5.000 sub-5MW blades needing to be exchanged, finding a cost-effective solution has become a necessity. One solution is to replace the jack-up vessel with a floating solution with similar workability. This can significantly save cost and time. That is why, TWD, together with Royal Wagenborg, have come up with an innovative floating removal and installation method.
The vessel independent tool is equipped with a motion compensation system to mitigate relative motions during turbine approach and allows for a safe connection. Once connected, a smart blade handling cart can collect, transport, and place blades and other heavy components of the nacelle. Due to its innovative character, the tool brings increased workability compared to other lifting solutions.
