Hindustan Shipyard Limited (HSL) has formally handed over ‘Nipun’ to the Indian Navy at Visakhapatnam.
This is the second indigenous Diving Support Vessel (DSV) created for naval deep-sea operations.

It is a first-of-its-kind naval ship designed for deep-sea diving, subsea salvage, submarine rescue, and search-and-rescue missions.
This ship is the second vessel under the Nistar-class DSV project, following its sister ship INS Nistar.
Engineers at Hindustan Shipyard Limited (HSL) designed and constructed the vessel in Visakhapatnam.
The vessel aims to strengthen India's strategic underwater capabilities and lower dependence on foreign rescue ships.

The vessel measures 4 meters in length with a total displacement exceeding 8,560 tonnes.
It contains 75%-80% indigenous content and uses specialized steel made completely by SAIL.
It features advanced diving equipment, a side stage, moonpool, and saturation systems for safe operation at extreme depths.
It functions as a mother ship to launch, track, and recover Deep Submergence Rescue Vehicles (DSRV) during emergencies.
It carries advanced subsea Remotely Operated Vehicles (ROVs) to monitor divers in real time and assist in salvage tasks.
The ship can stay at sea for 60 days without replenishment and has a flight deck for heavy Search and Rescue (SAR) helicopters.

It allows the Indian Navy to execute fast submarine rescues across the Indo-Pacific region without needing foreign help.
It highlights the growing capability of India's defence shipbuilding sector under the Aatmanirbhar Bharat initiative.
