Offshore Wind Turbine Installation Using a Double Slip Joint: Investigating the Installation Behavior of the Double Slip Joint During the Lowering Phase of a Wind Turbine Tower onto a Monopile

One of the challenges associated with offshore wind turbine installations is the mating phase. Aligning a transition piece onto its substructure under offshore conditions is a complicated and time-consuming procedure. Another issue found in a number of commissioned offshore wind turbines is related to the sustainability of the connection between...

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...
