Sagar Kanya — Research Vessel
After 38 years and over 400 research cruises (covering >1.5 million nautical miles), Sagar Kanya was formally decommissioned on April 29, 2021 at the Chennai Port. Reasons included:
Where is it now?
The vessel reportedly remains moored in Chennai as of 2025, with proposals to convert it into a floating museum or oceanographic training center—though this is not yet finalized.
Commissioned in 1983, the Sagar Kanya was acquired by the Government of India to give a much-needed boost to the nascent field of ocean science. Built in Denmark, this vessel was not just a ship; it was a floating laboratory designed to handle the rough seas and complex scientific demands of the Indian Ocean.
For nearly four decades, she has sailed under the Ministry of Earth Sciences (MoES), operated by the National Centre for Polar and Ocean Research (NCPOR). Her name, "Daughter of the Ocean," perfectly captures the grace and resilience required of a vessel spending months away from land. Sagar Kanya Research Vessel
Perhaps its most grueling voyages were to the "Furious Fifties" latitudes (50–60°S). Sagar Kanya undertook ten expeditions to the Southern Ocean to study the Antarctic Circumpolar Current, the largest ocean current on Earth. Data from these cruises revealed the rapid freshening of Antarctic bottom water due to ice sheet melting.
Following the devastating Indian Ocean Tsunami, Sagar Kanya was one of the first vessels on the scene to map the underwater seismic changes and assess the damage to the marine ecosystem, providing vital data for the early warning system built later.
One of the earliest major international collaborations involving Sagar Kanya. The vessel was stationed in the Bay of Bengal to study the genesis of monsoonal depressions. Data collected during this cruise improved India’s long-range monsoon forecasting models, which directly impacts the agricultural economy of 1.4 billion people.

Sagar Kanya is not a transport ship; it is a floating laboratory. Over its 40-year life, it has carried an evolving suite of instrumentation.
If you look out at the vast expanse of the Indian Ocean, it is easy to feel overwhelmed by its sheer scale. For decades, however, one ship has served as India’s steadfast sentinel on these waters, unlocking the mysteries of the deep.
She is the ORV Sagar Kanya (Ocean Research Vessel Daughter of the Ocean). Where is it now
While India launches satellites into space with remarkable frequency, the importance of exploring the "inner space"—our oceans—cannot be overstated. The Sagar Kanya has been the flagship of this aquatic exploration, playing a pivotal role in establishing India as a global leader in oceanography.
There is a growing movement within the Indian scientific community to designate Sagar Kanya as a National Maritime Heritage Site. Unlike a warship, which is designed for destruction, a research vessel is a symbol of creation. Proposals include:
