	Built by [[Garden Reach Shipbuilders & Engineers]] and launched in 1978 and commissioned at the [[Visakhapatnam]] naval base, ''Nirdeshak'' was a [[hydrographic survey]] ship within a series of indigenously designed and constructed ships. The ship was equipped with a helicopter and a Bofors 40mm gun for self-defense as well as four survey motor boats, and two small boats.

The ship was equipped with a helicopter and a Bofors 40mm gun for self-defense as well as four survey motor boats, and two small boats.

	''Nirdeshak'' was also equipped with a wide range of surveying, navigational and communication systems. The next-generation surveying systems fitted on-board included a multi-beam swath [[Echo (phenomenon)\|echo]] sounding system, a differential GPS, motion sensors, a sea gravimeter, a magnetometer, oceanographic sensors, side scan sonars, an automated data logging system, a sound velocity profiling system, and a digital survey and processing system. The equipment allows the ship to meet stringent international [[ISO 9002]] digital survey accuracy standards required for the production of electronic navigation charts and publications as per the [[International Hydrographic ~~Organisation~~]].

	''Nirdeshak'' was powered by two diesel engines for propulsion that provide the ship a capability of sustained speed and the ability to undertake a variety of tasks and rescue operations.

==Ship history==

Built by [[Garden Reach Shipbuilders & Engineers]] and launched in 1978 and commissioned at the [[Visakhapatnam]] naval base, ''Nirdeshak'' was a [[hydrographic survey]] ship within a series of indigenously designed and constructed ships. The ship was equipped with a helicopter and a Bofors 40mm gun for self-defense as well as four survey motor boats, and two small boats.

''Nirdeshak'' was also equipped with a wide range of surveying, navigational and communication systems. The next-generation surveying systems fitted on-board included a multi-beam swath [[Echo (phenomenon)|echo]] sounding system, a differential GPS, motion sensors, a sea gravimeter, a magnetometer, oceanographic sensors, side scan sonars, an automated data logging system, a sound velocity profiling system, and a digital survey and processing system. The equipment allows the ship to meet stringent international [[ISO 9002]] digital survey accuracy standards required for the production of electronic navigation charts and publications as per the [[International Hydrographic Organisation]].

''Nirdeshak'' was powered by two diesel engines for propulsion that provide the ship a capability of sustained speed and the ability to undertake a variety of tasks and rescue operations. In the aftermath of a 2004 tsunami, the ship was equipped with 45 beds, seven doctors and 35 medical attendants and was deployed to Indonesia to aid in the relief work.<ref>{{Cite web|title=Floating hospital on a mission to Indonesia|work=[[The Hindu]]|date=2005-01-10|url= http://www.thehindu.com/2005/01/10/stories/2005011011680400.htm}}{{dead link|date=April 2021|bot=medic}}{{cbignore|bot=medic}}</ref> The ship was also involved in a survey to excavate the ancient lost city of [[Dwarka]] in 2006.<ref>{{Cite web|title=K-caution at Dwarka Site|url=http://www.harekrsna.com/sun//news/08-07/news1428.htm}}</ref>

==Survey task==

The primary tasks of ''Nirdeshak'' included conducting hydrographic surveys, [[nautical chart]] preparation, [[cartography]] and training. To effectively conduct its work ''Nirdeshak'' was also equipped with [[Remotely operated underwater vehicle|ROV]]s, [[AUV]]s and [[Unmanned surface vehicle|USV]]s. In 2009, the ship conducted a hydrographic survey of [[St Brandon]], Black River Bay, [[Tamarin Bay]], [[Grand Bay, Mauritius|Grand Bay]] and [[Rivière des Galets (Mauritius)|Riviere des Galets]] as per the MoU{{clarify|date=March 2017}} signed between the two nations.<ref>{{Cite web|title=Visit of Indian Naval Survey Ship 'INS Nirdeshak'|url=http://indiahighcom-mauritius.org/pages.php?id=119}}</ref> In 2010, the ship conducted a hydrographic survey off the coast of Mauritius as per a [[MoU]] signed previously with the [[Government of Mauritius]].<ref>{{Cite web|title=Indian Navy deploys INS Nirdeshak for hydrographic assistance to Mauritius|url=http://www.brahmand.com/news/Indian-Navy-deploys-INS-Nirdeshak-for-hydrographic-assistance-to-Mauritius/3417/1/12.html}}</ref> The ship also performed a hydrographic survey off the coast of Seychelles around [[Praslin]] and [[Mahe, Seychelles|Mahe]], including approaches to the [[Port of Victoria (Seychelles)|Port of Victoria]].<ref>{{Cite web|title=Indian vessel to map out local waters|url=http://www.seychelles.net/seynat/archives/302101103.html}}</ref><ref>{{Cite web|title=Indian Navy deploys INS Nirdeshak for hydrographic assistance to Mauritius|url=http://www.sify.com/news/indian-navy-deploys-ins-nirdeshak-for-hydrographic-assistance-to-mauritius-news-national-kdsvEeigjecsi.html|archive-url=https://web.archive.org/web/20170227150322/http://www.sify.com/news/indian-navy-deploys-ins-nirdeshak-for-hydrographic-assistance-to-mauritius-news-national-kdsvEeigjecsi.html|url-status=dead|archive-date=2017-02-27}}</ref> In 2006 the ship was involved in an archaeological survey off the coast of Dwarka, using its sonar equipment to survey and generate a 3D model of the seabed in preparation for the work. The excavation was carried out in association with [[Archaeological Survey of India]], who guided the navy divers.<ref>{{Cite web|title=K-caution at Dwarka Site|url=http://www.harekrsna.com/sun//news/08-07/news1428.htm}}</ref>
