Operating Flange Clamp Tool

Install your foundations efficiently and safely with our Flange Clamp Tool

Flange Clamp Tools are used to temporarily secure the axial connection between the flanges of tower and substructure of a wind turbine generator prior and during the installation of permanent bolting. After installing the majority (or all) of the installation bolts, all Flange Clamp Tools are removed.

Once the Flange Clamp Tools are pre-installed and equally divided in the circumference of the given flange, all are connected into one system that can be operated remotely. This increases safety during offshore operations due to the fact that attending personnel during installation is no longer a requirement. Additionally, the temporary connection no longer warrants for a crane vessel during bolt installation, thus reducing installation time and increasing efficiency.

The Flange Clamp Tool is multi-functional and is mostly used at offshore floating wind projects, but can also be used in other on- and offshore projects.

HOW DOES THE FLANGE CLAMP TOOL WORK?

A Flange Clamp Tool system consists of a predetermined number of preinstalled Flange Clamp Tools, preferably equally divided over the circumference of the tower flange. Each system is connected to a Termination Panel that is remotely operated.

Once the Flange Clamp Tool is installed, the tower can be placed on the substructure and the temporary connection can be made with the Flange Clamp Tools. After the temporary connection, the bolts can be placed by personnel safely and the Flange Clamp Tools can be removed once all the bolts are fixed and tensioned.

The Flange Clamp Tool consist of two separate double acting cylinders who extend and clamp the flanges to make a fail safe connection.
