Titanium Alloy construction
381mm (15″) actuator stroke
139mT (306,000lbf) maximum actuation force
Hydraulic lock to maintain gate valve override
Customised high capacity LOT interface
Deployable by ROV or tool deployment unit
The tool uses a high capacity interface to transfer up to 139 metric tonnes (306,000lbf) of force onto the gate valve actuator and have a stroke of 381mm (15″). This interface is different to those specified in ISO 13628-8 as they are not capable of transferring this force.
The tool can be installed and operated using an ROV and can be hydraulically locked open. The main hydraulic cylinder is manufactured from a Titanium Alloy to minimise the weight and enable it to be rated to a higher operating load.
The tool can be provided with a hydraulic intensifier that is used to provide the operating pressure of 10,000psi (690bar) from the ROV hydraulics. If required, the tool can be customised for shorted strokes and mechanical locking mechanisms.
