an Indian under-development crewed deep-submergence vehicle intended to be utilised for deep sea exploration of rare minerals in the Indian Ocean. It is capable of diving down to a depth of 6,000 m. First uncrewed trial was conducted on 27 October 2021 where the 'personnel sphere' was lowered to a depth of 600 m, off the coast of Chennai. [28] [29]

A variable-buoyancy pressure vessel system is a type of rigid buoyancy control device for diving systems that retains a constant volume and varies its density by changing the weight (mass) of the contents, either by moving the ambient fluid into and out of a rigid pressure vessel, or by moving a stored liquid between internal and external variable-volume containers.
