‘Superskid’ gives Cougar a torque tool

It means that for some work tasks a small electric ROV can be deployed in the support role rather than a large hydraulic work class vehicle.

The innovation behind the work skids concept is an electro-hydraulic modular power package that allows a ‘mix and match’ combination of powerful tooling to be used.

Skids fitted with an ensemble of work-scope tooling such as a class 1-4 torque tool, 350bar sea water hot stab, manipulators, and high-pressure water jet and rotary brush for complimentary cleaning work, now make it possible for a small ROV to undertake the tasks normally performed by an hydraulic work-class vehicle but at a much lower cost.

And the recently launched Cougar XTi ROV has the pioneering architecture to absorb the work skid’s advanced technology ready for a range of demanding roles.

Smart fault diagnostics give the pilot a clear interpretation of any problem and the remedial action to be taken, including the ability to remotely isolate the failed component and keep the ROV working.

Each on board device, thrusters, lights, tools, etc, is managed through an intelligent three mode distributed plug and go control system. The first mode controls the device; the second provides the diagnostics; and the third is used for configuration.

Rated at 3,000m, and with six powerful thrusters, the Cougar XTi is highly manoeuvrable and with its new thinner umbilical, down from a typical 32mm to 20mm, drag through the water is reduced, particularly in strong currents.

The thinner umbilical has also reduced the size of the drum and shrunk the launch and recovery system into a more compact solution.

A new autopilot system gives the operator more precise positioning of the vehicle by automatically holding depth and heading in much tighter parameters than ever before.
