The C1 Wedge Connection can be used both in off- and onshore wind turbines as an alternative to bolted flange connections currently used in tubular steel wind turbine towers and foundations.The C1 Wedge Connection is currently being developed in collaboration with Siemens Gamesa and Delft University. Production, installation and behaviour of the connection were tested at full scale. In April 2019, C1 Connections began cooperating with Siemens Gamesa and Delft University to further develop the C1 Wedge Connection for application in wind turbine substructures. C1 Connections will, together with Siemens Gamesa and Delft University of Technology, continue its development towards market-readiness.
