The continuous growth in turbine size combined with harsher locations has pushed the limits of conventional bolted flanges and grouted connections.

The C1 Wedge Connection™ can deliver an ultimate resistance that goes far beyond the traditional bolted flange connections and a fatigue resistance that outperforms all bolted flange connections, making it the perfect solution for wind turbine connections. The connection is maintenance free and allows for safe, HSE friendly installation while driving down CAPEX.

The C1 Wedge Connection™ can be used for bottom-founded and floating wind turbines, both above and below water and is perfectly suited for floating installation.


The C1 Wedge Connection™ received the A-level certificate by DNV in March 2021.
