The indigenously developed vehicle is capable of crawling on the sea bed at a depth of six kilometre for 72 hours, he said.
"Similar to ISRO's plan to carry persons on a space mission, NIOT has undertaken Samudrayaan. The ₹200 crore project proposes to carry three persons in a submersible vehicle to a depth of 6000 metres under sea for various studies. Submarines go only about 200 metres," Atmanand said, responding to a query about deep sea mining.
The 'Samudrayaan' is a part of the Ministry of Earth Sciences' pilot project for deep ocean mining for rare minerals.
"We will go deeper in phases with more trials and the mining is expected to commence in 2022," Atmanand said.
He was in the city on Saturday to inaugurate a new coastal study vessel built by the Titagarh Wagons Ltd.
He also said this will be a part of the ₹6000 crore 'Deep Ocean Mission' that has received in-principle approval but is awaiting a final nod from the Union Finance Ministry.
"Final approvals are expected by October this year," Atmanand said.
India has been allocated a site of 75,000 sq km in the Central Indian Ocean Basin by the International Sea Bed Authority for exploration of polymetallic nodules from seabed.
The estimated resource of polymetallic nodules is about 380 million tonnes, containing 4.7 million tonnes of nickel, 4.29 million tonnes of copper and 0.55 million tonnes of cobalt and 92.59 million tonnes of manganese.
