Rovotics Develops ROVs and Subsea Components for Inspections and Surveys

Published: 14 Apr 2019 | Author: Mike Rees

Rovotics, a leading manufacturer of ROVs (Remotely Operated Vehicles) and subsea components for inspections and surveys, has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Silver’ profile highlights how their state-of-the-art, robust ROV systems maximise efficiency and minimise downtime for a wide variety of subsea applications, including oil & gas, geological surveying and maritime construction.

Shark G2R Inspection Class ROVThe Shark G2R Inspection Class 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.

Shark G3R Inspection Class ROVThe Shark G3R Survey Class ROV delivers 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. It 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.

Shark G4R Electric ROV for Subsea InspectionsThe Shark G4R Work Class ROV is Rovotics’ largest and most versatile ROV, providing 244kg of bollard pull while fielding a 280kg 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 seven high-reliability SPE-250 thrusters (four lateral, three vertical). It can be equipped with a 7-function and a 5-function manipulator, and tools for a range of operations including cutting, jetting, dredging and cleaning. 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.

The RONAV is a high-accuracy GNSS receiver for ROV navigation and positioning, using GPS, GLONASS, and BeiDou, with capability for Galileo and QZSS. The system can utilise long-range RTK baselines of up to 50 km, with fast acquisition times, and is compatible with many RTK sources including ROX Format, RTCM, CMR and CMR+.
