This torque tool has been specifically developed to provide the highest level of performance. It has integral torque
and turns counting sensors. When matched with a FORUM supplied torque tool control manifold, it can provide precise
feedback on torque response of any subsea operation. These can alternatively be utilised by connecting a FORUM
Universal Subsea Display (supplied), which would give a visual read-out of live torque feedback and turns count.

The tool conforms to the ISO 13628-8 Fig 18 Class 1-4 bucket interface used extensively in the subsea industry for
valve overrides operated by ROV. The tool has latching wings allowing the tool to hold on to the interface. The latching
wings are hydraulically driven forward, and spring retracted. Thus, in the case of a loss of hydraulic power the wings
will release. The tool uses a high specification drive motor for consistent torque output characteristics, even if used with
direct hydraulic pressure control without the feedback sensor. The motor shares casing oil with the gearbox therefore
avoiding the need for a separate compensator.

Note that for applying torques less than 108Nm (80 ft lbs) the class 1&2 tool is recommended.
