80kNm Gearbox
The 80kNm Gearbox is an ROV tool designed and tested to operate subsea valves with torque requirement of 80kNm.
Description
The 80kNm Gearbox is an ROV tool designed and tested to operate subsea valves with torque requirement of 80kNm. The torque tool is providing 80kNm output torque with input torque from standard API17H Class 7 Torque Tool – Long Version. It has been optimized to ROV flyable, i.e. the submerged weight is 70kg due to buoyancy elements integrated in the design.
The gearbox is landed on to valve and uses 4 off reaction wings to ensure alignment with valve interface. The Gearbox is then rotated with torque tool to ensure alignment of output shaft with valve stem. The ROV bucket handle on top of the tool is for ROV operation and it is hinged to lay it down before inserting torque tool. The gearbox is operated by our Quattro Control System.
