SAN ANTONIO – Forum Subsea Technologies is displaying the capabilities of its ISO Class 1-4 torque tool at the Subsea Tieback Forum & Exhibition currently being held at the Henry B. Gonzales Convention Center in San Antonio, Texas.
Forum says that the torque tool has been specifically developed to provide the highest level of performance, and features integral torque and turns counting sensors. When matched with a PSS-supplied torque tool control manifold, it can provide precise feedback on torque response of any subsea operation. These can alternatively be utilized by connecting a PSSL 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 which allow it 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.
