The high demand for clean energy is driving a growth in the number and size of offshore wind turbines. These larger turbines require heavier lifts and higher reaches, which often exceed the current crane capacities of jack-up vessels.
In addition, pile connections are not currently future proof, presenting a number of challenges. This includes the long curing time required for the grout, extended installation times and the high maintenance cost of bolted flanges. The required manual work also carries additional safety risks.
Therefore, KCI have developed the Double Slip Joint (DSJ) to provide an alternative. It is quicker to install and reduces the pile weight thanks to its innovative underwater connec¬tion.
