Tasks
Investigator's primary tasks are hydrographic survey, nautical chart preparation, cartography and training, and it is equipped with a remotely operated underwater vehicle (ROV), an autonomous underwater vehicle (AUV) and an unmanned surface vehicle (USV). In early 2008, the ship conducted a hydrographic survey in Seychelles in cooperation with the Seychelles Coast Guard (SCG) and the Seychelles People's Defence Force (SPDF). The survey covered the entire 32-nautical-mile (59 km; 37 mi) coast, from North Point to Petite Anse, replacing navigational charts made in 1890.[4] Investigator conducted survey work in and around western Mahe that year (to facilitate the preparation of a new navigational chart that year),[3] In the same year, Investigator also conducted survey work in Mauritius, and surveyed 30 percent of the St. Brandon shoals (part of the Outer Islands of Mauritius) to update charts first prepared in 1851 and create a profile for a Mauritius Oceanography Institute–Commission on the Limits of the Continental Shelf survey.[5] The survey of the Saya de Malha Bank allowed the government of Mauritius to claim an extended continental shelf beyond its exclusive economic zone.[6] In 2013, the Investigator surveyed the seas around the Andaman and Nicobar Islands. This survey was necessitated by the 2004 Indian Ocean earthquake and tsunami, which made massive geomorphological changes to the islands and their surrounding seafloor (affecting the movement of ships and smaller watercraft).[2]
In May 2019, it was brought under Southern Naval Command and was rebased to Kochi.[7]
