'''INS ''Sarvekshak'' (J22)''' ([[Hindi]]: सर्वेक्षक, lit.surveyor) is a hydrographic [[survey ship]] in the [[Indian Navy]], under the [[Southern Naval Command]]. Apart from a [[helicopter]] and Bofors 40 mm gun, the ship is also equipped with four survey [[motor boats]], two small boats.<ref name="Michel">{{Cite web|title=Indian naval ship's commander calls on President Michel after survey mission|url=http://primezonelalola.blogspot.in/2011/12/indian-naval-ships-commander-calls-on.html|access-date=20 February 2017|archive-date=20 February 2017|archive-url=https://web.archive.org/web/20170220173136/http://primezonelalola.blogspot.in/2011/12/indian-naval-ships-commander-calls-on.html|url-status=dead}}</ref> The ship was awarded the runner-up trophy in the 2015 Innovation Trophy awards given out on [[Navy Day]] as an operational unit by [[Prime Minister of India|Prime Minister]] [[Narendra Modi]]. The award was given for developing an innovative solution for [[tide|tidal]] measurement during [[hydrographic survey]]s by use of land based [[terrain mapping]] equipment and floating [[buoy]]s mounted with [[Prism (optics)|prisms]]. The award was accepted by Captain Rajesh Bargoti, the commanding officer of INS ''Sarvekshak''.<ref>{{Cite web|title=Award of Innovation Trophy to Indian Naval Personnel by Hon'ble Prime Minister on Navy Day 2015|url= http://pib.nic.in/newsite/printrelease.aspx?relid=132581}}</ref>

==Ship history==
Built by [[Goa Shipyard Limited]] and [[Ship commissioning|commissioned]] into the Naval service at [[Kochi]] [[naval base]] in 2002, ''Sarvekshak'' is the Indian Navy's eight [[hydrographic survey]] and perhaps the last ship under ''Sandhayak'' class to have been indigenously designed and constructed.

INS ''Sarvekshak'' is equipped with a range of 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 [[sonar]]s and an automated data logging system as well as state-of-the-art Digital Survey and Processing System, sound velocity profiling system among others. These systems 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]].<ref name="Visit">{{Cite web|title=Visit of INS Sarvekshak to Mauritius|url=http://indiahighcom-mauritius.org/pages.php?id=162}}</ref>

''Sarvekshak'' is powered by two [[diesel engine]]s and is capable of sustained speeds. The ship's multi-role capability places her in the league of the most versatile survey vessels in the world. It can undertake a variety of tasks under trying conditions.

==Primary task==
The primary task of INS ''Sarvekshak'' includes hydrographic surveys, [[nautical chart]] preparation, [[cartography]] and training. The ship is also equipped with [[Remotely operated underwater vehicle|ROV]], [[AUV]] & [[Unmanned surface vehicle|USV]].<ref>{{Cite web|title=INS Sarvekshak |url=https://www.hydro-international.com/content/company/ins-sarvekshak}}</ref> As part of protocol the ship also took part in [[International Defence Exhibition]] 2009 held at [[Abu Dhabi]].<ref>{{Cite web |title=INS Sarvekshak to Attend IDEX 2009 at Abu Dhabi |url=http://www.marinebuzz.com/2009/02/21/ins-sarvekshak-to-attend-idex-2009-at-abu-dhabi/ |access-date=15 February 2017 |archive-date=15 February 2017 |archive-url=https://web.archive.org/web/20170215205833/http://www.marinebuzz.com/2009/02/21/ins-sarvekshak-to-attend-idex-2009-at-abu-dhabi/ |url-status=dead }}</ref> In 2015 ''Sarvekshak'', was deployed to [[Mauritius]] for five weeks to help in survey operations.<ref>{{Cite web|title=Deployment of INS Sarvekshak to Mauritius for Survey Operations |url=https://www.indiannavy.nic.in/content/deployment-ins-sarvekshak-mauritius-survey-operations}}</ref> INS ''Sarvekshak'' was also deployed in 2011 to Mauritius as part of survey operations to execute the following tasks in three phases.

<ol type="a">
<li>Survey off Rodrigues for delineation of Continental shelf</li>
<li>Survey of [[Port Louis]] [[Harbour]]</li>
<li>Survey of passes off Mauritian [[Coast]]</li>
<li>Checking serviceability of survey equipment held with [[Government of Mauritius]]</li>
<li>Undertake training of Mauritian survey officers and NCG personnel</li>
</ol>

INS ''Sarvekshak'' had previously visited Mauritius in February 2006 and March 2007 to undertake hydrographic surveys. The survey work by INS Sarvekshak was of immense help to Mauritius with regards to fishing, [[ecosystem]] [[Habitat conservation|preservation]] and management, establishment of [[artificial reef]]s, delimitation of the Continental Shelf of Mauritius and safe [[navigation]] of ships and crafts.<ref name="Visit"/> In 2007 the ship surveyed [[Port Mathurin]], Rodrigues, which was last surveyed 133 years ago.<ref>{{Cite web|title=Signing of Protocol for Sale of Navigational |url=http://indiahighcom-mauritius.org/pages.php?id=120}}</ref>
In 2011 the ship was also deployed in [[Seychelles]] to carry out hydrographic surveys off the [[atoll]] of [[Aldabra]], [[Picard Island]], Polyminie and part of [[Malabar Island]] and Grande-Terre island on the request of [[Government of Seychelles]] as the last survey of the area was done back in 1960s.<ref name="Michel"/> As a part of goodwill tour 20 students from [[Jammu and Kashmir (state)|Jammu and Kashmir]] also toured the ship in 2011.<ref>{{Cite news|title=Kashmir students arrive in Kochi on a goodwill visit |newspaper=The Hindu |date=18 September 2011 |url=http://www.thehindu.com/news/cities/Kochi/kashmir-students-arrive-in-kochi-on-a-goodwill-visit/article2464739.ece}}</ref>

On 26 December 2024, INS Sarvekshak reached [[Port Louis]], [[Mauritius]] for Joint Hydrographic Survey.<ref>{{Cite news |date=2024-12-27 |title=INS SARVEKSHAK ARRIVES AT PORT LOUIS |url=https://pib.gov.in/PressReleasePage.aspx?PRID=2088480 |access-date=2024-12-27 |work=[[Press Information Bureau]]}}</ref>

==Solar power==
[[File:INS Sarvekshak's flexible solar panels in use at sea.jpg|thumb|Flexible solar panels on board the ship]]
In 2017, ''Sarvekshak'' became the 1st [[List of active Indian Navy ships|ship of Indian Navy]] ever to deploy [[solar power]]. The installation cost was around Rs. 19 lakh. The estimated savings for a lifespan of about 15 years is around Rs. 1 crore. The current diesel generator consumes a litre of diesel to produce five units{{clarify|reason=what units?|date=January 2026}} of electricity. [[Captain (Indian Navy)|Captain]] Rajesh Bargoti, the commanding officer of the ship, said, "It took about six months to put the entire system in place. We are now using [[solar energy]] for lights and a couple of [[air conditioners]]."<ref>{{Cite web| title=In A First, Indian Navy Installs Solar Power System On Its Survey Ship |url=http://topyaps.com/navy-installs-solar-panels-ship|archive-url=https://web.archive.org/web/20170214115141/http://topyaps.com/navy-installs-solar-panels-ship|url-status=usurped|archive-date=14 February 2017}}</ref> The estimated profit generated in a ship service life of 25 years is Rs 2.7 crore in this small project alone. "Even if the system is used for 25 days in one year, the system can repay its cost in less than 10 years while protecting the nature," the Navy said.

Indian Navy claimed that the 300-Watt panels will generate about 5.4 kW solar power system, and avoid around 165 kg of carbon a day, "So in its 25 years life the total carbon saved is around 15 lakhs kg and 5.75 lakh litres of diesel by this innovation".<ref>{{Cite news| title=INS Sarvekshak goes green; instals solar power system |newspaper=The Economic Times |url=http://economictimes.indiatimes.com/news/defence/ins-sarvekshak-goes-green-instals-solar-power-system/articleshow/57110554.cms}}</ref><ref>{{Cite web| title=Solar power lights up INS Sarvekshak |website=[[The Times of India]] |date=12 February 2017 |url=http://timesofindia.indiatimes.com/city/kochi/solar-power-lights-up-ins-sarvekshak/articleshow/57102784.cms}}</ref>{{dubious|date=January 2026}} Noting that the world is looking for clean, renewable sources of energy in order to protect and reduce the harm caused to the environment, the Navy said the deterioration of the environment is highly correlated to the production and usage of fossil-based fuels worldwide. The Navy said it has created a new mechanism to encourage the utilization and development of [[renewable energy]] resources.<ref>{{Cite web| title=INS Sarvekshak goes green; instals solar power system |date=12 February 2017 |url=http://indianexpress.com/article/india/ins-sarvekshak-goes-green-instals-solar-power-system-4520969/}}</ref>
