The H-ROV Ariane, designed by Ifremer, can be operated in tethered (ROV) or autonomous (AUV) modes.
Tethered mode can be used for close inspection and intervention tasks where the operator controls the vehicle on real time using a patented actuator system. The H-ROV can be operated in autonomous mode either as a safety fallback strategy in case of tether rupture, or as a dedicated mission such as performing a structural inspection of subsea processing system, the company explained.
Scientific Exploration and Intervention up to 2,500 Depth
The H-ROV offers wide possibility for scientific community to explore and undertake intervention tasks in different seabed morphology, emphasis on canyons, cliffs and steep inclines providing 2D and 3D mosaic, close-up inspection, light tools manipulating, optical imaging and acoustic mapping. This system is able to gather specific sample thanks to a motorized tools bay, a water and faunal specimen sampler combining with an electrical reversible water ballast system. Additionally, the full electrical manipulators manufactured by ECA Group guarantee a cost effective solution for reducing maintenance costs and enhancing reliability compare to traditional hydraulic system.
Opportunities for Oil and Gas Industry
This convergence of AUV and ROV technologies, creates a great opportunity in Oil & Gas industry. With a fully autonomous ROV control program, the system will perform safer and faster operations in case of unexpected environmental conditions which would cause to break sequences or execution steps. Pre-sequenced operation tasks and hands-free ROV navigation, means the vessel can be automated offering greater efficiency in construction sequences. Further development of thehybrid technology with the possibility of a resident solution semi-permanently installed in subsea operations, will soon be considered as a new way to reduce operational expenditure in Life of Field and Inspection Repair Maintenance (IRM) market.
