Limits of Offshore Wind Turbine Installation with the Double Slip Joint: Offshore WTG Tower Lowering and Mating with a Double Slip Joint Connection Using Catchers and Tower Guidance. A Determination of Installation Limits and Exploration of Workability

In current offshore wind turbine (WTG) tower installations, bolted flange connections are common. These connections are however reaching their limit due to the maximized size of the bolts. Also, bolted connections require the motions between the tower and foundation to be limited during installation, suggesting their workability of installation...
