Scientists on board study water temperature, salinity, ocean currents, and chemical composition to understand ocean dynamics. 2. Geological Surveying
It operates on a diesel-electric propulsion system. Four main generators (2,820 kW total) provide power to a single controllable-pitch propeller. While this reduces fuel efficiency compared to modern ships, it provides exceptionally quiet operations—critical for acoustic research (echo sounding, sub-bottom profiling). The vessel also includes a bow thruster for dynamic positioning, allowing it to maintain a fixed point over a deep-sea site without dragging anchor.

While less advanced than modern US or European vessels, Sagar Kanya was superior to most Asian contemporaries (China’s Shiyan 1 was launched later, but initially smaller). It gave India a head start in Indian Ocean governance (UNCLOS).

Designed as a versatile, multi-disciplinary platform, the ship features a robust hull capable of enduring harsh weather conditions in the open ocean. Key Specifications 71.5 meters Breadth: 12.8 meters Draft: 4.3 meters Displacement: Approximately 3,850 tonnes Endurance: 45 days at sea Cruising Speed: 10.5 knots
As India moves forward with the , there is a growing need for even more advanced vessels capable of carrying autonomous underwater vehicles (AUVs) and manned submersibles. However, the Sagar Kanya continues to be a symbol of India's self-reliance in marine science. Conclusion Four main generators (2,820 kW total) provide power
For over four decades, the Oceanographic Research Vessel (ORV) Sagar Kanya has stood as a testament to India's commitment to exploring, understanding, and harnessing the mysteries of the ocean. As the country's first deep-sea, multidisciplinary research vessel, has been an unwavering asset, contributing significantly to India's marine research, resource exploration, and the training of countless marine scientists since its commissioning in 1983.
Some of its most notable contributions include:
Over its long career, ORV Sagar Kanya has participated in numerous national and international programs, generating a wealth of scientific data. Its very first scientific cruise (July-September 1983) took it off the coast of Kenya for an Indo-Kenya joint study, focusing on monsoon energetics and water mass structure.
