Garden Reach Shipbuilders and Engineers (GRSE) has launched 'Sagar Manthan', a state-of-the-art indigenous Ocean Research Vessel (ORV). This vessel is set to revolutionize India's deep-sea exploration and mineral discovery capabilities.

  • 'Sagar Manthan' is an indigenous ORV built by GRSE for the National Centre for Polar and Ocean Research (NCPOR).
  • Capable of geophysical seismic surveys at depths of up to 6 km.
  • Integral part of the ₹4,077 crore Deep Ocean Mission launched in 2021.

In a significant boost to India's maritime scientific prowess, Garden Reach Shipbuilders and Engineers (GRSE) in Kolkata has launched 'Sagar Manthan'. This indigenous Ocean Research Vessel (ORV) has been commissioned for the National Centre for Polar and Ocean Research (NCPOR), operating under the Union Ministry of Earth Sciences. The launch is particularly noteworthy for its efficiency, occurring just five months after the vessel's keel-laying.

Technical Specifications and Capabilities

The 'Sagar Manthan' is an engineering marvel, measuring 89.5 meters in length and 18.8 meters in width, with a gross tonnage of 5,900 tonnes. Designed for endurance and precision, the vessel can reach speeds of up to 14 knots. Its primary scientific utility lies in its ability to conduct underway swath multibeam and geophysical seismic surveys in both coastal and deep waters, reaching depths of up to 6 kilometers.

Why This Matters

BozokMedia analysis shows that India has long suffered from a critical gap in its research fleet. With many existing vessels aging or lacking modern instrumentation, Indian scientists were frequently forced to lease expensive international vessels for specialized mineral exploration. 'Sagar Manthan' eliminates this dependency, ensuring data sovereignty and reducing operational costs while accelerating the pace of discovery.

"The deployment of Sagar Manthan signifies India's transition from a coastal observer to a deep-ocean explorer, securing our interests in the global Blue Economy."

Advanced Research Functionalities

Beyond mapping, the vessel is equipped for Conductivity, Temperature, and Depth (CTD) profiling and complex biological sampling. It can facilitate surface and deep-sea mooring and data buoy operations, as well as seabed sampling using corers and rock dredging. Crucially, the ship serves as a mothership for Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs) developed by the National Institute of Ocean Technology.
