Mission Samudrayan

Q What is Mission Samudrayan ?

  • The Samudrayan project has been undertaken by the National Institute of Ocean Technology (NIOT).
  • It will be a part of the Rs 6,000 crore Deep Ocean Mission.
  • It is designed to carry 3 persons in 2.1meter diameter Titanium Alloy Personnel Sphere with an operational endurance of 12hrs and systems to support emergency endurance up to 96hrs.
  • It could work at a depth between 1000 and 5500 meters.

 

Q What are its Objectives ?

  • Samudrayan shall facilitate carrying out deep ocean exploration of the non-living resources such as polymetallic manganese nodules, gas hydrates, hydro-thermal sulphides and cobalt crusts.
  • The mission would carry out subsea activities such as high-resolution bathymetry, biodiversity assessment, geo-scientific observation, search activities, salvage operation and engineering support.

 

Q What are focus areas of the Project ?

  • Ocean climate change advisory services
  • Underwater vehicles
  • Underwater robotics-related technologies
  • Deep-sea mining: Exploitation of polymetallic nodules

 

Q What are Components of the mission ?

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, Ballast and Trim System
  • Pressure compensated batteries and propulsion system, control and communication systems and Launching and Recovery System.

 

Q How much progress has been achieved  till date ?

  • The preliminary design of the manned submersible MATSYA 6000 is completed.
  • 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.

 

Q What is need such mission?

  • This manned submersible mission 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.
  • With Samudrayan, 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.
