This torque tool has been specifically developed to provide the highest level of performance.
It has integral torque and turns counting sensors for closed loop control.
When matched with a FORUM supplied torque tool control manifold, it can provide
precise feedback on torque response of any subsea operation. These can alternatvly
be utilised by connecting a FORUM Universal Subsea Display, which would give
a visual read-out of live torque feedback and/or turns counter. USD sold separately.
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 reccomended
