Traditional observation and light work class are not operative on ship hulls or on large vertical structures when the objective is to run a close and systematic TV inspection, a metal thickness measurement or eventually cleaning. The ECA Group hybrid vehicle swims as an ROV, and, when reaching the vertical structure, crawls along it while remaining, even in rough sea conditions, firmly stuck onto it thanks to a strong thrust.
Application for Maritime sector
- FPSO, Rigs inspection & cleaning
- ROVING BAT : Multi-purpose hybrid ROV + crawler
- Swims, tilts, rolls, sticks and crawls thanks to: -6 very strong thrusters -2 sets of motorized tracks
- Inspects and measures thanks to tv cameras and various sensors
- Local cleaning with dedicated module
- Auto docking function on vertical surface or underneath horizontal surfaces
Rover for Hull Inspection and Cleaning
Range of solutions achieved by Roving Bat
- Rig or FPSO hull inspection
- Rig or FPSO thickness and NDT measurements
- Rig or FPSO hull cleaning
Rig or FPSO hull inspection
The ROVING BAT-INS is equipped with TV cameras for the visual inspection of the hull structural integrity. Also, equipped with an imaging sonar (BlueView, Didson...); the inspection in very high turbidity water is possible.
Rig or FPSO thickness measurement
The ROVING BAT can carry several NDT sensors used to validate the conformity of a vessel, verify structural integrity, assess corrosion and wear; such as:
- Several aligned hull thickness measurement sensors (UT probes)
- Others NDT sensors (CP probe...) mountable on 5 function manipulator arm for measurement of elements difficult to reach
Cleaning tools for NDT
A cleaning module incorporating a hydro-jetting or a brushing system performs local cleaning of the ship hull, thus permitting the use of NDT sensors such as Ultrasonic probes for hull thickness measurements, or CP probes.
Challenge for both applications: remains onto the hull surface. The powerful thrust from its 4 vertical props will secure that the Roving Bat sticks onto the hull while in operation, even in strong current conditions.
