Undersea Submersible Vehicle

After two years break, India’s dream of constructing a submersible vehicle is back, and it has planned to build the new submersible vehicle to explore Deep Ocean. The Chennai-Based National Institute of Technology (NIoT) has decided to create the submersible vehicle part by part with outside support and merge it on its own.

Scientists said that making of the undersea vehicle is tougher than building the space mission, why because the vehicle would be subjected to greater water pressure when it dives down the deep ocean. Speaking to the media, NioT scientist and former director Dr. M.A. Atmanand said, “We had offering issues earlier for the whole manned submersible, which caused the delay. We have designed the specifications of the manned submersible with an endurance of 12 hours when it is operating at a depth of 6,000 meters in the ocean”.

Just Like how we have developed Space technology independently, we want India to manufacture on its own instead of buying it from others, he said. The manned submersible takes nearly three to four hours to reach the undersea. At a depth of 6000 meters, each part of your body or vehicle’s surface will be exposed to a heavy pressure that is 600 times higher than what is felt at the sea level.

He said, “NIoT has already tested unmanned submersible and remote operated vehicle at 6,000 meters. We also successfully verified the soil tester, and we have full confidence in both ROV and soil tester. But, for the manned submersible, we will take the help of ISRO, which is working on the manned lunar mission, or the Navy that has submarines.”

What are the main uses with Undersea Trip?
  • Submersible shave many uses worldwide, such as oceanography, underwater archaeology, ocean exploration, adventure, equipment maintenance and recovery and underwater videography.
  • The submersible design will be made of titanium alloys to tolerate pressures in the range of 500 to 600 bars at 6,000 depth.
  • The crew will be compressed in the pressure body in the crew compartment with life support systems.
  • UP to now only five countries like the US, France, Russia, Japan and China have technology to manufacture it.
