Vessel Classification & Yard Identity- Engineered as an indigenous, all-weather, multidisciplinary Ocean Research Vessel (ORV) designated as Yard 3041.
Physical & Propulsion Specifications- Measures 89.5 metres in length and 18.8 metres in beam, displaces a gross tonnage of 5,900 tonnes, and attains speeds up to 14 knots at 90% Maximum Continuous Rating (MCR).
Deep Ocean Mission Alignment- Constructed under Vertical-4 (Deep Ocean Survey and Exploration)of the Government of India’s flagship Deep Ocean Mission (DOM).
Rapid Construction Timeline- Launched just five months after its keel-laying (April 2026), reflecting accelerated domestic execution in complex non-combatant scientific shipbuilding.
Operational Design Life- Engineered for a service lifespan of 30 years, capable of sustaining long-endurance expeditions in extreme oceanic conditions, including the Southern Ocean.
Dual Regulatory Classification- Built in strict compliance with international maritime safety codes, holding dual-class certification from the Indian Register of Shipping (IRS) and the American Bureau of Shipping (ABS).
Replacement Strategy & Transition to Self-Reliance
Phasing Out Legacy Foreign Tonnage- Positioned to replace the 43-year-old ORV Sagar Kanya, which was procured from Germany in 1983 and long served as India's oceanographic workhorse.
Aatmanirbharta in Research Fleets- Marks a decisive shift from foreign vessel acquisitions to indigenous design, engineering, and outfitting by Indian defence public sector shipyards.
Expanding Polar & Marine Horizons- Paves the way for the Ministry of Earth Sciences' planned acquisition of subsequent specialized vessels, including a dedicated Polar Research Vessel (PRV).
Civilian-Defence Shipbuilding Convergence- Leverages GRSE’s four decades of naval survey vessel expertise (e.g., INS Sagardhwani, Sandhayak-class Large Survey Vessels like INS Sanshodhak).
Strategic Indigenous Value Chain- Engages domestic MSMEs and Indian precision-engineering firms for onboard scientific outfitting, hydraulic winches, and acoustic sensor mounts.
Sub-Surface Interoperability- Serves as a versatile surface platform capable of integrating technologies engineered across premier national institutes like NIOT, INCOIS, and NIO.
Underway Swath Bathymetry- Equipped with multibeam bathymetric sonar arrays and sub-bottom profilers to map deep-sea floor topography at depths up to 6,000 metres (6 km).
Geophysical Seismic Exploration- Fitted with multichannel seismic systems and acoustic drop-keels for seabed stratification studies and tectonic fault line identification.
Autonomous & Robotic Vehicle Deployment- Features specialized stern A-frames and heave-compensated handling gear to deploy and recover Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs) developed by NIOT.
Oceanographic Water-Column Profiling- Executes high-precision Conductivity, Temperature, and Depth (CTD) profiling, rosette water sampling, and vertical/horizontal multi-net biological collections.
Geological Benthic Sampling- Capable of surface/deep-sea mooring operations, seabed coring, grab sampling, and rock dredging via heavy-duty chain-bag dredges.
Onboard Laboratories & Data Processing- Houses clean analytical wet/dry laboratories, allowing scientists to perform preliminary sample analysis, data synthesis, and geochemical processing at sea.
Strategic, Economic & Environmental Applications
Critical Minerals & Hydrothermal Sulphides- Mandated to survey polymetallic hydrothermal sulphides and seafloor mineral deposits along active tectonic spreading ridges in the Central and Southwest Indian Ocean.
Marine Biodiversity & Bioprospecting- Supports deep benthic biological surveys to document extreme microbial biodiversity, deep-sea fauna, and genetic resources for biomedical applications.
Climate Change & Southern Ocean Studies- Collects air-sea interaction data, upper-air meteorological metrics, and ocean current profiles to refine monsoonal forecasting models and study the global carbon sink.
Early Warning Infrastructure- Assists in maintaining offshore moored tsunami buoy networks and national ocean-observing arrays for disaster forecasting in the Indian Ocean Region.
Blue Economy Acceleration- Strengthens the data foundation for India’s Blue Economy policy by identifying offshore hydrocarbon seeps, gas hydrates, and living/non-living seabed resources.
Academic & Scientific Human Capital- Acts as an operational floating academy, offering training and field research opportunities for oceanographers, marine geologists, and technical crew.
Geopolitical Dimensions & Indian Ocean Governance
Sovereignty Across the Extended Continental Shelf- Generates scientific geophysical data required to substantiate India's claims over its Extended Continental Shelf before the UN Commission on the Limits of the Continental Shelf (UNCLOS-CLCS).
International Seabed Authority (ISA) Obligations- Directly fulfills exploratory survey commitments for India's allotted contract areas in the Indian Ocean basin for hydrothermal sulphides and polymetallic nodules.
Maritime Domain Awareness (MDA)- Continuous acoustic, bathymetric, and oceanographic data generation enhances underwater domain awareness, supporting maritime navigation safety and sub-surface security.
Regional Collaborative Research- Provides India with an advanced scientific platform to extend oceanographic partnerships to littoral states under the SAGAR (Security and Growth for All in the Region) framework.
Countering Research Dominance in the IOR- Deepens India's scientific presence and surveillance footprint across critical sea lanes amidst growing deployments of foreign oceanographic vessels in the Indian Ocean.
Data Sovereignty- Prevents reliance on third-party bathymetric datasets by establishing an indigenous, verified oceanographic database crucial for civilian resource planning and naval operations.
