The hydraulic clamshell grab is designed to recover or move materials from the seabed floor during subsea operations. The tool is designed to be crane deployed and can recover either coarse or bulky materials.
The tool consists of a large clamshell grab positioned at the center of the tool with a total SWL of up to 8Te. A hotstab receptacle with pressure gauge and counterbalance valve to open & close the grab and ensure pressure can be ‘locked in’ allowing the grab to remain closed when the hotstab is removed from the receptacle.
The tool also has a circular ROV grab bar around the tool, so that the tool can be positioned subsea by the ROV. The grab bar can also be used to stabilize the vehicle when inserting the hotstab or viewing the pressure gauge.
The tool can also be configured to be surface fed with downlines, removing the need for the hotstab and hotstab receptacle.
