'''INS ''Sandhayak'' (J18)'''([[Hindi]]: संधायक lit. coordinator) is the lead ship of the {{sclass|Sandhayak|survey ship|4}} of [[survey ship]]s. The ship operates as a hydrographic survey ship in the [[Indian Navy]], under the [[Eastern Naval Command]]. Apart from a helicopter and Bofors 40 mm gun for self defence, the ship is also equipped with four survey motor boats, two small boats. The ship can also analyse the level of pollution, sea level at various places, sea bed and marine wealth. ''Sandhayak'' is capable of conducting shallow coastal and deep oceanic hydrographic survey and collect oceanographic and geophysical data.<ref>{{Cite web|title=Naval survey ship in Rameswaram |url=http://indiatoday.intoday.in/story/naval-survey-ship-in-rameswaram/1/618359.html}}</ref> The ship was decommissioned on 4 June 2021 after 40 years in service.<ref>{{cite web|url=https://pib.gov.in/PressReleasePage.aspx?PRID=1723980|title=INS Sandhayak to be Decommissioned on 04 Jun 21|publisher=PIB|date=2021-06-03}}</ref>

==Ship history==
Built by [[Garden Reach Shipbuilders & Engineers]] and commissioned into the Naval service at [[Visakhapatnam]] naval base in 2001, ''Sandhayak'' is actually the Indian Navy's fifth [[hydrographic survey]] ship in the series [[indigenous peoples of Asia|indigenous]]ly designed and constructed.

''Sandhayak'' is equipped with a range of [[hydrographic survey|surveying]], navigational, and communication systems. The next-generation surveying systems provided onboard include multi-beam swath [[Echo (phenomenon)|echo]] sounding system, differential [[global positioning system]], [[motion sensors]], sea [[gravimeter]], [[magnetometer]], oceanographic sensors, side scan sonars and an automated data logging system as well as Digital Survey and Processing System, sound velocity profiling system among others. The equipment allow the ship to meet the stringent international/[[ISO 9002]] digital survey accuracy standards required for the production of electronic navigation charts and publications as laid down by the [[International Hydrographic Organization]]. ''Sandhayak'' is powered by two diesel engines and is capable of sustained speeds and can also undertake a variety of tasks including rescue operations. In March 2017 in a rare case of [[insubordination]] and [[indiscipline]] 3 [[sailors]] were airlifted from the ship while it was conducting [[training]] session off the coast of [[Paradip]], [[Odisha]] in the [[Bay of Bengal]].<ref>{{Cite web|title=Navy airlifts three sailors aboard ship for indiscipline|url=http://www.newindianexpress.com/nation/2017/mar/09/navy-airlifts-three-sailors-aboard-ship-for-indiscipline-1579612.html}}</ref>

==Survey Task==
The primary task of ''Sandhayak'' includes hydrographic surveys, [[nautical chart]] preparation, with [[cartography]] and training. ''Sandhayak'' is also equipped with [[Remotely operated underwater vehicle|ROV]], [[AUV]] & [[Unmanned surface vehicle|USV]]. In 2013 ''Sandhayak'' conducted hydrographical survey of the Islands of [[Andaman & Nicobar]] to update charts, as the seabed in the area has undergone drastic hydrological changes with regard to coastal, underwater profile after the [[2004 Tsunami]]<ref>{{Cite web|title=INS Sandhayak Establishes Depths of 10-20 mtrs [sic] inside Middle Strait for Safe Navigation by Bigger Bo|url=http://www.andamanchronicle.net/index.php?option=com_content&view=article&id=1076:ins-sandhayak-establishes-depths-of-10-20-mtrs-inside-middle-strait-for-safe-navigation-by-bigger-bo&catid=37:top-news&Itemid=142}}</ref> In 2015 ''Sandhayak'' was used to conduct a search of the sea floor of the missing [[Dornier 228]] of the [[Indian Coast Guard]] and was successful in detecting the beacon signals of the missing aircraft.<ref>{{Cite web|title=Naval survey ship INS Sandhayak picks up beacon signals from missing Dornier aircraft|date=13 June 2015 |url=http://www.news18.com/news/india/naval-survey-ship-ins-sandhayak-picks-up-beacon-signals-from-missing-dornier-aircraft-1005688.html}}</ref> In 2016 ''Sandhayak'' conducted a survey off the coast of [[Rameswaram]] in a bid to find a new seaway that will allow larger ships to traverse the narrow [[Palk Strait]].<ref>{{Cite web|title=Naval survey ship in Rameswaram |url=http://indiatoday.intoday.in/story/naval-survey-ship-in-rameswaram/1/618359.html}}</ref>
