Union Earth Sciences Minister Jitendra Singh on Friday launched India's first manned ocean mission "Samudrayan" at Chennai.With the launch of this unique ocean mission, India joins the elite club of nations such as the US, Russia, Japan, France, and China to have such underwater vehicles for carrying out subsea activities, a release from the Earth Sciences Ministry said."This niche technology shall facilitate Ministry of Earth Sciences in carrying out deep ocean exploration of the non-living resources such as polymetallic manganese nodules, gas hydrates, hydro-thermal sulphides and cobalt crusts, located at a depth between 1,000 and 5,500 metres," the Minister said.He said that the preliminary design of the manned submersible MATSYA 6000 is completed and realisation of the vehicle has been started with various organisations including the ISRO, the IITM and the DRDO roped in to support the development.Jitendra Singh said that sea trials of 500 metre-rated shallow water version of the manned submersible are expected to take place in the last quarter of 2022 and the MATSYA 6000, the deep-water manned submersible will be ready for trials by the second quarter of 2024.

"The advancing technologies in metallurgy, energy storage, underwater navigation and manufacturing facilities provides opportunity for developing more efficient, reliable and safe manned submersible," he said.The underwater vehicles are essential for carrying out subsea activities such as high-resolution bathymetry, biodiversity assessment, geo-scientific observation, search activities, salvage operation, and engineering support."Even though unmanned underwater vehicles have improved manoeuvring and excellent vision systems resembling direct observation, manned submersible provides a feel of direct physical presence for researchers and has better intervention capability. With the advancing subsea technologies, the recent Fendouzhe manned submersible developed by China in 2020 has touched 11,000m water depths," he added.Ministry officials said that based on the experience gained over two decades in the development of unmanned robotic vehicles and systems for 6,000 m operational capability, the Ministry and the NIOT is indigenously developing a manned submersible with a depth capability of 6,000 metres under the aegis of Deep Ocean Mission.

The manned submersible is designed to carry three persons in 2.1 metre diameter titanium alloy personnel sphere with an operational endurance of 12 hour and systems to support emergency endurance up to 96 hour.Some of the critical subsystems of the manned submersibles are development of titanium alloy personnel sphere, human support and safety system in enclosed space, low density buoyancy modules, and the ballast and trim system (BTS).Others include pressure compensated batteries and propulsion system, control and communication systems and launching and recovery system.The system design, concept of operation, subcomponents functionality and integrity, emergency rescue, and failure mode analysis are reviewed and certified as per the rules of International Association of Classification and Certification Society for man-rated usage of manned submersible at a depth of 6,000 metres.
