CHENNAI, Oct 29 : Union Minister of State (Independent Charge) Science & Technology; Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh launched here today, India’s first Manned Ocean Mission “Samudrayan”.
Addressing the Scientists at the National Institute of Ocean Technology (NIOT) Chennai after the formal ceremony, the Minister said, with this launch, India joins the elite club of nations such as USA, Russia, Japan, France and China to have such underwater vehicles for carrying out subsea activities. This opens a new chapter for exploring ocean resources for drinking water,clean energy and blue economy, he said.
Dr Jitendra Singh said, this niche technology shall facilitate Ministry of Earth Sciences, MoES 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 1000 and 5500 meters. He said, the preliminary design of the manned submersible MATSYA 6000 is completed and realization of vehicle is started with various organization including ISRO, IITM and DRDO roped-in to support the development.
The Minister informed 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. He said, the advancing technologies in metallurgy, energy storage, underwater navigation and manufacturing facilities provides opportunity for developing more efficient, reliable and safe manned submersible.
Dr Jitendra Singh said that 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. He said, even though unmanned underwater vehicles have improved maneuvering 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 ~11000m water depths, the Minister added.
Some of the critical subsystems of the manned submersibles are development of Ti Alloy Personnel Sphere, Human support and safety system in enclosed space, low density buoyancy modules, Ballast and Trim System. Pressure compensated batteries and propulsion system, control and communication systems and Launching and Recovery System.
