SMART TORQUE TOOL ADVANCES AN ALL ELECTRIC FUTURE
A breakthrough in electric torque tool technology is set to further advance the capability of electric underwater robotic vehicles.
A new lightweight electric torque tool is being launched globally in a collaboration agreement between Saab Seaeye, the world leader in electric underwater e-robotic systems, and Australia-based Total Marine Technology (TMT).
New small self-calibrating class 1-4 torque tool to bring considerable savings to torque tool tasks with the use of smaller electric work vehicles.
The tool is smart, light, simple to fit, fast to set-up, has an advanced, high accuracy torque control system and can operate across the Saab Seaeye range of e-robotic vehicles, opening up new market opportunities.
Considerable savings will come from using compact electric e-robotic vehicles and electric tooling for tasks normally performed by much larger hydraulic vehicles.
No smaller electric class 1-4 torque tool exists on the market and with a singlehanded weight of just 24 kilos, it is around half the weight of a typical hydraulic torque tool, reducing the risk of manual handling injuries.
A major benefit for subsea operators is the tool's ability to adapt automatically to Class 1 to 4 fittings and torques whilst performing the integrity-critical task of opening and closing seabed valves and other torque tensioning tasks.
Torque accuracy is vital for operators needing to trust a system not to damage a valve when opening and closing. Electric torque systems are far more accurate over the whole torque range when compared to hydraulic systems and deck calibration is quick, repeatable and simpler, saving setup cost.
Helps avoid risk to older valves
An electric system can provide highly accurate small torque values so is extremely useful where there is an inherent risk of damage to older valves when turned, as they may be in poor condition.
The electric torque tool with its built-in drive and torque measurement is effectively self-calibrating across its full torque range, saving considerable operation and vessel time — and significant costs.
Current hydraulic torque tools operated by hydraulic vehicles are typically set and checked multiple times for a particular torque range before each dive, using a tested and certified calibration unit. Whereas in future the electric torque tool need only be calibrated by an independent body on an annual basis.
Accuracy and control are standout features with the TMT torque tool as the software-managed system allows much finer control and feedback than hydraulic systems. Operators control torque pressures by dialing in torque limits, speed, and number of turns and watch the response on screen immediately. Pitch and roll sensors in the tool aid rapid alignment during critical tasks.
