The Hindustan Shipyard Limited (HSL) delivered the indigenously built DP-II Diving Support Vessel (DSV) Nistar to the Indian Navy at the Eastern Naval Command (ENC) on July 8, said a release on Thursday.

Designed as a mother ship for a Deep Submergence Rescue Vessel (DSRV), Nistar is a critical asset for submarine rescue missions and crew evacuation

It was formally made through a document signed by HSL CMD Commodore Hemant Khatri, and Commander Amit Subhro Banerji, Commanding Officer of Nistar, in the presence of Rear Admiral Ravnish Seth, Chief Staff Officer (Technical).

The 118-metre-long, 10,000-tonne vessel is equipped with state-of-the-art diving systems, enabling deep-sea saturation diving and submarine rescue operations up to 300 metres.

The vessel houses remotely operated vehicles (ROVs) capable of monitoring divers and conducting underwater salvage tasks at depths of up to 1,000 metres.

Approximately 75% of the vessel is built using indigenous components.

Following the delivery of INS Dhruv in 2020, Nistar is HSL’s second major strategic platform for building advanced naval assets.
