was the name of a British company and the marking "1792" which is presumed to be the date of their manufacture. Moreover, the ingots bear the emblem of the Dutch East India Company. Navy divers carried out further dives at the site and identified a two-metre long cannon which, although attached to the wreck, was deeply embedded in the seabed. The ship’s diving team managed to recover the cannon, despite adverse sea conditions and the ship not being equipped to carry out excavations. The cannon, which was covered with extensive marine growth, is 2.1 metres in length and weighs approximately 700 kg. Survey work INS Darshak in 2016 completed the hydrographic survey of Tanga Port, Tanzania coast for the Government of Tanzania. This survey work was of particular importance for the country's government due to upcoming oil pipeline being laid at the port from Uganda. In late 2016 the ship also carried out survey work off the waters of Mauritius to prepare two new charts of the Mauritian waters as per charting scheme agreed the two governments. The survey was useful for the tourism industry based in northern Mauritius. Areas off Mon Choisy, Grand Bay and other smaller islands in the north were surveyed comprehensively. Also survey data was collected for aquaculture site off Anse La Raie and deep sea transacts for scientific research at request of Mauritius Oceanography Institute. The survey is also expected to help in Deep Ocean Water Application Projects done on request of Continental Shelf Department of Prime Minister's Office. Earlier in 2015, INS Darshak conducted hydrographic survey in Seychelles for a period of 1 month concentrating off the coast of Port Victoria and in nearby areas covering the north east of the island of Mahé, Seychelles. On 3 March 2017 the ship was deployed to Sri Lanka for a two-month-long hydrographic survey trip in collaboration with Sri Lanka Navy. During the trip Sri Lanka Navy personnel joined their counterparts on the ship to undertake advanced hydrographic practices. The ship also made port calls to Colombo and Galle.
