Let’s make connections safer

Designed with HSE in mind

Installation of conventional heavy loaded bolted L-flanges, such as those found at the interface between monopiles and transition pieces and between foundations and towers, is at odds with the HSE regulations on maximum allowable weights to be lifted.

Bolt assemblies are often above the allowable weight limit as are the tools that are required to torque or tension them. In many cases workers are present below suspended loads for the alignment of the bolt holes which is inherently unsafe.

The C1 Wedge Connection™ addresses these issues by keeping components and tools that need to be lifted manually below the allowable safe weight limits, ensuring safe and fast installation. 

Increasing safety while improving the connection

Safety is key

Creating a safe working environment

The alignment of the C1 Wedge Connection™ does not require for people to be below suspended or hooked-on loads. No lifting of components is needed, since all fasteners can be pre-placed on the connection and pushed in radially once the tower has been securely quick-connected to the foundation. 

This makes the C1 Wedge Connection™ the safe alternative for heavy loaded bolted connections.

More benefits

Simple to design

The design is typically governed by the overturning moment and the diameter of the connection.

CAPEX savings

The C1 Wedge Connection™ allows for significant savings on primary and on secondary steel.

High Capacity Connection

The C1 Wedge Connection™ can outperform conventional connections on capacity.
