In certain configurations, flexible risers or umbilicals need to be secured to the seabed. This is often done by means of steel tether clamps, tether systems or seabed anchors. Trelleborg Offshore Tether Systems include a clamp which is designed to withstand high differential axial loads with a Tether base at the bottom of the structure. The Tether base is a structure which secures the Tether system to the seabed
Connects to the Pad Eyes of the Tether Clamp, allows connection and disconnection by ROV
Often the anchors may comprise of multiple units which may each be easily lifted by the crane capacity available on offshore installation vessels. The multiple units are then designed to 'dock' together to provide a single structure with the required total weight in water.
