Context

The Nirdeshak vessel was launched in Kattupalli, Chennai by the Indian Navy.

The Nirdeshak vessel is the second of the four Survey Vessels (Large) (SVL) Project.
- The first vessel named “Sandhayak” was launched in December 2021.
It is being built as a Public-Private Partnership model by Garden Reach Shipbuilders Engineers (GRSE), a defence PSU in collaboration with L&T shipbuilding for the Indian Navy.
The ship has been named after the Nirdeshak Vessel which was an Indian Naval Survey ship decommissioned after 32 years of service in 2014.

The SVL vessels will replace the Sandhayak Class survey ships equipped with modern and advanced generation hydrographic equipment that helps collect oceanographic data.
The key function of these vessels would be to undertake full-scale coastal and deep-water hydrographic surveys of ports and navigational channels.
The body of these vessels is made from indigenously developed DMR 249-A, steel manufactured by the Steel Authority of India Limited.
The SVL ships have a deep displacement of about 3400 tons and can accommodate about 235 personnel.
The ships are designed to operate at a cruise speed of 14 knots and a maximum speed of 18 knots.
These ships can carry four Survey Motor Boats and an integral helicopter.
