The off-vessel tensioning system uses a fairlead at the hull with bollard pull from an anchor handler…
The in-line tensioner is an ongoing development arising from work with Shell on the Vito project and then Tullow.
The compact under water fairlead was designed to be mounted on a top loaded suction pile to enable tensioning to be accrued out and work with the BTC at the hull or buoy.
The BTC system uses a ROV insertable sheave locked in position above the BTC female mounted on trunnions. This sheave allows a manmade fibre rope to be led through the bore of the BTC female and connected to the BTC male mid water.
