The Indian Navy on Thursday dispatched its Deep Submergence Rescue Vessel (DSRV) to help the Indonesian Navy in search and rescue operations for the Indonesian submarine, KRI Nanggala, with 53 sailors onboard, which went missing during a torpedo drill on Wednesday. The Indian Navy has dispatched its Deep Submergence Rescue Vessel (DSRV) to help in Search & Rescue efforts for KRI Nanggala. The DSRV is a special vessel that undertakes such tasks.
Indian Navy Spokesperson Commander Vivek Madhwal said that the DSRV has been despatched from its base at Visakhapatnam, located on the east coast of the country. The DSRV a side-scan sonar for locating the position of the submarine in distress at sea, providing immediate relief by way of posting emergency life support containers with the help of a Remotely Operated Vehicle (ROV). The crew inside the submarine can be rescued after that using the DSRV itself. Submarine rescue is required when a submarine is reported missing and special equipment is needed for underwater search to locate the disabled watercraft and rescue the personnel trapped inside. The Indian Navy’s DSRV system can locate a submarine up to 1,000 metres of depth using its advanced Side Scan Sonar (SSS) and Remotely Operated Vehicle (ROV).
After the submarine is successfully located, another sub-module of DSRV, the Submarine Rescue Vehicle (SRV), will join the submarine to rescue the trapped personnel. The SRV can also be used to provide emergency supplies to the submarine.
