In 2013, engineering firm KCI started a research project in collaboration with Delft University of Technology and developed the Double Slip Joint: an innovative technology that connects the monopile and transition piece for wind turbines at sea

This connection has two major advantages: it is maintenance-free and the new technology significantly reduces installation time, resulting in major cost savings. A consortium was formed, made up of KCI, Van Oord and Sif, in order to finance a lab test and work out a complete business case based on development, manufacturing and installation aspects. As part of this consortium, in 2017 Sif made a prototype that is being tested at WMC under the supervision of KCI and Van Oord. On 10 August, the first results were demonstrated by KCI.
