TMT Electric Torque Tool

TMT Electric Torque Tool

Subsea Torque Tool
Torque tool operations can now be delivered from any electric inspection class ROV.
The patent pending, TMT Electric Torque Tool, has an intuitive and comprehensive user interface. In automatic mode, the torque limit, number of turns and speed limit parameters are set via a custom software application. This allows the tool to function autonomously to achieve the specified outcomes safely.  In the alternative manual mode, the same outcomes are entered but the operator selects the valve operating parameters.
The tool’s electric servo motor drive unit offers superior controllability of torque and speed as opposed it’s hydraulic counterparts. The electric drive also provides the full rated torque at near linearity, from zero to maximum RPM.
The servo motor’s integrated resolver feedback provides high resolution positioning detail. When this is coupled with the accurate strain gauge torque feedback on the output stage of the gearbox, it provides superior measurement information compared to other available tools.
The TMT Electric Torque Tool’s innovative end effector design allows for the operation of Class 1 to 4 fittings without changing the tool or bringing the ROV to the surface.
The small size of the TMT Electric Torque Tool allows it to be easily packaged into two carry-on sized helicopter compliant cases, allowing rapid delivery to site.
TMT can customise the tool to suit your requirements.
