The Indian Navy hydrographic survey ship, INS Jamuna (J16) is currently on a deployment to carry out Joint Hydrographic Survey off the South – West coast of Sri Lanka.
A team of Sri Lankan Navy hydrographers including officers and sailors have also been embarked onboard the vessel for the duration of the survey.
Over the last ten days, the ship has undertaken several survey activities as part of the Foreign Cooperation Survey along with the Sri Lanka Navy hydrographers. A detached survey camp comprising sailors from the Indian and Sri Lankan Navies have been undertaking observation round the clock. The detached survey camp is also tasked for fixing of navigational aids and delineation of high water line. The ship’s helicopter was also utilized for the survey operations.
INS Jamuna (J16) is a Sandhayak-class hydrographic survey ship of the Indian Navy, under the Southern Naval Command (SNC).
Built by Goa Shipyard Limited (GSL) and commissioned into the Navy at Kochi in 1991, Jamuna is the Indian Navy’s third hydrographic survey ship of the Sandhayak-class to have been indigenously designed and constructed. The namesake of the vessel is HMIS Jumna, a Black Swan-class sloop, which served in the Royal Indian Navy (RIN) during World War II.
The Sandhayak-class vessels equipped with four survey motor boats, two small boats and are powered by two diesel engines with a top speed of 16 knots (30 km/h; 18 mph). They have a helicopter deck and are also armed with a Bofors 40 mm/60 gun mount for self-defense.
The ships are equipped with a variety of next-generation surveying systems including multi-beam swath echo sounding system, differential GPS, motion sensors, sea gravimeter, magnetometer, oceanographic sensors, side scan sonars, automated data logging system, sound velocity profiling system, digital survey and processing system. The ships are also equipped with Remotely Operated Vehicle (ROV), Autonomous Underwater Vehicle (AUV), and Unmanned Surface Vehicle (USV).
The ships are designed to undertake shallow coastal and deep oceanic hydrographic surveys and collect oceanographic and geophysical data required for the production of digital navigational charts and publications. Besides carrying out their primary role of hydrographic survey, they can also assist in times of war and natural calamities as troop transports and casualty holding ships.
