Rovotics
Rovotics Subsea Technology

Established in 2011, Rovotics is a leading manufacturer of ROVs (Remotely Operated Vehicles) for subsea inspections and surveys. We also provide subsea components including GNSS receivers for ROVs and CP equipment.

ROVs for Inspections and Surveys

Our state-of-the-art robust ROV systems and advanced software maximise efficiency and minimise downtime, and have been successfully deployed for a wide variety of applications, including oil & gas, geological surveying and maritime construction.

A technical training course is included as part of our comprehensive after sales support, and we offer free replacement Rovotics parts for the first year, if required.

Shark G2R ROV

Highly Efficient Inspection Class ROV

Shark G2R Inspection Class ROVThe Shark G2R ROV features a high-power-to size ratio, with over 80kg of bollard pull while fielding a 35kg payload. With a strong aluminium and polypropylene construction, it is rated for operation at up to 500m, with an optional upgrade extending this to 1000m.

The ROV is powered by six high-reliability SPE-75 thrusters (four lateral, two vertical), incorporating unique Statorshield technology that allows the thrusters to continue operation even in the event of shaft seal failure.

Each part of the Shark G2R has its own dedicated processor, maximising efficiency and speed of operation. A +/- 90 degree closed-loop tilt unit, with 1-degree position accuracy, can be fitted with a light and up to two cameras.

Specifications:

Dimensions (LxWxH) 1150x750x590mm (height 750mm with skid)/td>
Weight 140kg (180-220kg with payload)
Payload (weight in water) 35kg
Depth Rating 500m (1000m optional)
Forward Speed >3 knots
Thrust 80kg forward, 70kg backward, 50kg vertical

Shark G3R ROV

High Performance Survey Class ROV

Shark G3R Inspection Class ROV

The Shark G3R ROV features a high-power-to size ratio, with 130kg of bollard pull while fielding a 100kg payload. With a strong aluminium and polypropylene construction, it is rated for operation at up to 500m, with a series of optional upgrades extending this to 1000m, 2000m or 3000m.

The ROV is powered by six high-reliability SPE-250 thrusters (four lateral, two vertical), incorporating unique Statorshield technology that allows the thrusters to continue operation even in the event of shaft seal failure.

The Shark G3R can be equipped with two heavy-duty 5-function manipulators, or a survey skid for remote pipeline inspection applications. A wide variety of sensors and payloads can be fielded on the ROV, including bathymeters, Doppler Velocity Logs (DVL), Ultra-Short BaseLine (USBL) acoustic positioning systems, and pipeline trackers. A pan/ tilt unit, with 1-degree position accuracy, can be fitted with up to two lights and two cameras.

Specifications:

Dimensions (LxWxH) 1600x1080x885mm (height 1235mm with skid)
Weight 350kg (600-700kg with payload)
Payload (weight in water) 100kg
Depth Rating 500m (1000m, 2000m, 3000m optional)
Forward Speed 3 knots
Thrust 130kg forward, 130kg backward, 90kg vertical, 92kg lateral
