In News:

• The Indian Navy has inducted a Submarine Rescue System with a Deep Submergence Rescue Vessel (DSRV) along with associated equipment.

Deep Submergence Rescue Vessel (DSRV):

• The Indian DSRV has the capability to rescue personnel from a distressed submarine (DISSUB) up to a depth of 650 m and it is the latest in terms of technology and capabilities.
• It has been designed and supplied to meet unique requirements of our submarines by M/s James Fishes Defence, UK.
• This System has a Side Scan Sonar for locating the position of the submarine in distress at sea.
• It will be providing immediate relief by way of posting Emergency Life Support Containers with the help of Remotely Operated Vehicle (ROV) for the rescue.
• To ensure early mobilization, the System permits rapid transportation of the Rescue System from the base to the exact location of the distressed submarine by transportation using air/land/sea vessels.

Importance of DSRV system:

• The Indian Navy currently operates submarines of the Sindhughosh, Shishumar, Kalvari Classes as well as nuclear powered submarines.
• The operating medium and the nature of operations undertaken by submarines expose them to high degree of inherent risk. In such an eventuality, traditional methods of search and rescue at sea are ineffective for a disabled submarine.
• To overcome this capability, gap the Navy has acquired a third generation, advanced Submarine Rescue System considering of a Non-tethered Deep Submergence Rescue Vehicle (DSRV) and its associated equipment.
