2.Operation NISTAR Successfully Culminates with Safe Disembarkations of 38 Indian Nationals at Porbandar

Operation NISTAR

  • INS Sunayana successfully evacuated 38 Indian Nationals at/ off Socotra Islands during a swift Humanitarian and Disaster Relief Operation (HADR), code named Operation NISTAR.
  • The Indian Nationals were stranded after severe Cyclonic Storm – Mekunu devastated the area around Socotra Island.

Humanitarian Assistance and Disaster Relief (HADR) in India’s National Strategy

  • HADR operations have attracted the attention of the global community in recent years.
  • The Indian armed forces have a wide experience of disaster relief operations both at home and abroad, where they have been the core of relief operations.
  • Due to its sub-continental size, geographical location and its vulnerability to disasters, India has kept its forces ready to render assistance at short notice.
  • In the six decades since independence, India has experienced a number of natural and man-made disasters such as floods, earthquakes, famines, industrial accidents etc.
  • At the same time, India has partnered the global community in providing relief in affected regions.

3.INS Karanj boosts Navy’s firepower

Third Scorpene class submarine joins Naval fleet

  1. The Navy’s third state-of-the-art Scorpene class submarine, INS Karanj, has been launched

4.Indian Navy inducts its first Deep Submergence Rescue Vehicle

  • The Indian Navy has inducted its first Deep Submergence Rescue Vehicle (DSRV) System at the Naval Dockyard in Mumbai.

About DSRV

  1. DSRV is used to rescue crew members stranded in submarines that get disabled. The Indian Navy joins a select group of naval forces in the world that boasts of this niche capability.
  2. The DSRV can be operated at a depth of 650 meters and can hold around 15 people.
  3. The Indian Navy in March 2016 had commissioned two DSRVs, the second will deployed at the Eastern Naval Command in Visakhapatnam.
  4. The induction of the DSRV marks the culmination of years of effort of the Indian Navy in acquiring this niche submarine rescue capability.

Why need DSRV System?

  1. The Indian Navy currently operates submarines of the Sindhughosh, Shishumar, Kalvari Classes as well as nuclear powered submarines.
  2. The operating medium and the nature of operations undertaken by submarines expose them to high degree of inherent risk.
  3. In such an eventuality, traditional methods of search and rescue at sea are ineffective for a disabled submarine.
  4. 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.

What makes Indian DSRV special?

  1. The Indian Navy’s DSRV System is considered to be the most advanced system currently in operation globally for its capability of undertaking rescue from a disabled Submarine upto 650 m depth.
  2. It is operated by a crew of three, can rescue 14 personnel from a disabled Submarine at one time and can operate in extreme sea conditions.

5.Indian Navy’s Deep Submergence Rescue Vessel (DSRV) Capability

Context

  • 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)

  1. 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.
  2. It has been designed and supplied to meet unique requirements of our submarines by M/s James Fishes Defence, UK.
  3. This System has a Side Scan Sonar for locating the position of the submarine in distress at sea.
  4. 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.
  5. 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.
