Navy Hydrographers Show Interest In AUV
By SP's Special Correspondent

January 11, 2016: Kickstarting its hunt in 2014, the Indian Navy's Hydrography Department has revived its interest in a brand new AUV technology. In keeping with the existing effort, it has decided to upgrade its surveying capabilities by acquiring a new autonomous underwater vehicle (AUV) that can be deployed off its existing and new hydrography survey vessels. The AUV will be used to undertake hydrographic surveys at medium and deep depths away from the operating ship using hydrographic payloads. The Navy has set down that the AUV needs to be capable of hydrographic and oceanographic surveys and reconnaissance, collection of bathymetric data, specialised mapping, conduct of route surveys, collection of high-resolution, high precision seabed and sub-bottom data and collection of tactical intelligence. The system needs to also come equipped with various hydrographic sensor payloads capable of mapping the seabed through swath bathymetry and seabed imagery by means of continuous acquisition of seafloor sonar images. The Navy wants an AUV with a complete inertial navigation system capable of guiding the vehicle in autonomous, semi-autonomous and supervised mode of operation. The AUV unit needs to be not more than 7 metres long and weighing no more than 1,000-kg, with a maximum operating depth of 1,000 metres and a speed of 7 knots in upto Sea State 3. It also needs to be capable of 24-hour endurance with payloads on at nominal power.

Yes with India's N arm increasing with SSN and SSBN we need these beauties to help us with hydrography survey and oceanographic survey too. The depths of 400-800 m range is very important to us now going forward. The AUVs can be a asset in this regard..

L&T pioneers torpedo-tube AUV

Adamya autonomous underwater vehicle (AUV) developed and built in-house by L&T Heavy Engineering. According to L&T, "Adamya is the next step into the world of unmanned naval warfare and coastal defence. Its unique design allows it to be launched from the torpedo tube of a submarine—a pioneering feat globally."

L&T has highlighted several features on the Adamya to the Navy, including the fact that the vehicle's modular design and depth-rated shells enable mission customisation as per the Navy's needs without having to resort to pressure-proofing of the internal electronic systems. Other qualities include short turnaround time and ability to be air-shipped conveniently. The Adamya is being pitched for naval applications that include hydrographic survey (the Hydrography Dept. incidentally is also looking for AUVs), mine countermeasures, intelligence-surveillance-reconnaissance (ISR), offshore survey, clandestine monitoring, environmental monitoring and optional anti-submarine warfare. The 18.7 feet, 850 kg platform sports an endurance of 8 hours at 4 knots (with maximum forward speed of 6 knots) with a customisable depth rating of 500 metres.
