The new standard in connections

The C1 Wedge Connection (patent pending) is the safest and fastest connection, with low CAPEX and low OPEX levels.

The C1 Wedge Connection uses a fastener that comprises of an upper and a lower block to pull down a fork shaped upper part over a lower part. The pre stressed connection has much higher ULS and FLS capacity than any bolted connection.
The symmetric connection combined with the pre stress and the very fatigue insensitive details gives the connection superior fatigue resistance.


C1 Wedge Connections can be employed both above and underwater:

Above water:

  • monopile to transition piece
  • foundation to tower
  • between tower segments
  • tower to nacelle


  • between monopile segments
  • in jackets
