Indigenously designed and built at HSL, these ships are a true testimonial to 'Aatmanirbharta'. They are self-sustaining platforms which can operate at sea for prolonged durations.

DSVs equipped with an array of complex Diving Support systems and Deep Submergence Rescue Vessel (DSRV) will be deployed for deep sea diving and submarine rescue operations. Furthermore, the ships will be capable of conducting Search and Rescue operations and carrying out Helicopter Operations at sea.

This project is being executed with support from Indian industry primarily MSME firms who have supplied Yard material, equipment and services. Shipyard is extensively using the GeM portal for procuring material and services for the project. More than 120 MSME vendors across India have actively participated in the Project.

"Nistar" and "Nipun" were launched by achieving approx 80% indigenous content, a major step towards 'Self Reliance'. DSV project has generated local employment opportunities and promoted indigenisation which will boost India's economy.

The length of the Diving Support Vessels is 118.4 meters and at the highest point, their width is 22.8 meters. Their displacement capacity is about 9,350 tonnes. Also, they have the capacity to carry 215 sailors and can operate continuously at sea for a period of 60 days.

The ships are powered by two main engines, which can travel at a maximum speed of 18 knots.

Hindustan Shipyard Limited (HSL) is a shipyard located in Visakhapatnam on the east coast of India. By 2009, over 192 vessels had been built at HSL through 2009 and the shipyard had repaired almost 2000 ships. It builds bulk carriers, offshore patrol vessels, survey ships, drill ships, offshore platforms and repair and support vessels.
