Visakhapatnam: Indian Navy dispatched its deep submergence rescue vessel (DSRV) on 22 April to assist Tentara Nasional Indonesia-Angkatan Laut (Indonesian Navy) in its search and rescue efforts for the Indonesian submarine KRI Nanggala which was reported missing on 21 April.
On Wednesday, the Indian Navy received an alert through the International Submarine Escape and Rescue Liaison Office (ISMERLO) regarding the missing Indonesian submarine. The submarine was reportedly exercising at a location 25 miles north of Bali with a crew of 53 personnel.
Submarine rescue is required to be undertaken when a submarine is reported to be missing or sunk. Specialized equipment is required for underwater search to locate the disabled submarine and rescue the personnel who are trapped inside.
India is amongst the few countries in the world capable of undertaking the search and rescue of a disabled submarine through a DSRV. Indian Navy's DSRV system can locate a submarine up to 1,000 m depth utilizing its state-of-the-art side-scan sonar and remotely operated vehicle. After the submarine is successfully located, another sub-module of DSRV, the submarine rescue vehicle, mates with the submarine to rescue the trapped personnel. The SRV can also be used to provide emergency supplies to the submarine.
Under the framework of comprehensive strategic partnership between India and Indonesia, the Indian Navy and the Indonesian Navy share a strong partnership of operational cooperation. The two navies have been exercising regularly in the past and have developed synergy and interoperability which is considered important for the present mission.
