One worker has been killed and two others are injured in an accident at an under-construction nuclear submarine site in Visakhapatnam where India is building its first class of three nuclear-powered ballistic missile submarines.
The incident took place when the pressure of the hydraulic tank of the Arihant class submarine was being tested and the tank's lid fell on the workers at Building-5 of the shipbuilding cente, Defence Research Development Organisation (DRDO) chief Avinash Chander told reporters.
"The submarines are safe and the accident does not adversely affect the project," the statement from DRDO said.
"During testing of a pressure tank at a facility of Department of Defence R&D related to development of submarines at Vishakhapatnam, an accident took place while testing of a pressure tank at about 5 pm in the evening," a statement by the DRDO stated.
INS Arihant, which is likely to go on trials any day, has not been damaged.
An inquiry into the accident has reportedly been ordered by the DRDO chief.
This comes just a day after a gas leak on an under-construction ship at the Mazagaon dock in Mumbai killed one Navy officer. Carbon dioxide had leaked from a malfunctioning unit during machinery trials of a yet-to-be-commissioned Kolkata class ship.
Only last week, two officers were killed in a fire aboard a Navy submarine INS Sindhuratna, which had been refitted and was being sea-tested.
