See Saab Seaeye’s range at Seawork

Four key underwater vehicles will be featured on Saab Seaeye’s Stand D16 at Seawork 2012, including the new double-hulled Sabertooth AUV/ROV.

The Panther XT Plus offers 50% more power.

The new double-hulled version of the Sabertooth offers twice the operational duration of the single hulled Sabertooth launched last year. It can have a range of over 40 miles, has 14 hours duration, and can be depth rated to 3,000m.

The unique Sabertooth concept combines the technologies of both AUV and ROV into a single unified resource with the range and manoeuvrability of an AUV and the tooling capability of a light-work ROV.

Three operational modes are possible; autonomous roaming, attached fibre-optic cable, and umbilical for power and communications.

It can embark on long range programmable missions or under operator control around set targets, with obstacle avoidance and precise manoeuvrability. It can work down deep tunnels or inside complex structures where its 360° manoeuvrability allows it to orientate into any position, even directly up or down.

In places where access is seasonally restricted, it can remain underwater for a year at an isolated location, ready to be deployed as needed. Tooling packs can be stored at its docking station, batteries can be re-charged, data and video downloaded and fresh instructions uploaded.

Panther XT Plus

The new Panther XT Plus sees a breakthrough in power management that offers 50% more power. Fitted with ten powerful thrusters it can swim 30% faster than any other electric work ROV in its class.

The Panther XT Plus can maintain position whilst working in strong currents greater than four knots. For an operator, the exceptional number of thrusters also delivers a reassuringly high level of redundancy.

A greater payload, along with a re-designed frame, offers more heavy duty power and space for fitting a greater range of tools and sensors, including industry standard Schilling seven function position feedback manipulators.

Cougar XT Compact

For operation in high currents and shallow waters typically encountered in offshore wind farm installations, a new compact version of the successful Cougar range has been created to minimise the effect of current velocity.

The result is an ROV with a reduced frame size, buoyancy and weight. A thinner 17mm tether also minimises drag. Overall, the compact design has the highest thrust to weight ratio in its class.

Falcon

The Falcon’s design makes it small enough to manhandle into the water, yet powerful enough to hold steady in strong cross currents and operate a range of accessories and tools.

It is packed with technological innovations such as intelligent ‘plug-and-go’ electronics for rapid role change during operations. This means that up to 128 different devices can be fitted, including extra cameras, lights, tracking system, manipulator and sonar, plus the option of adding special tooling on a removable skid.

For survey work, the Falcon has the advantage of a low electrical and acoustic noise signature that allows for optimum survey sensor data.
