Death on nuclear follow up boat under construction
Compromises with safety norms and practices are playing havoc with lives on board ships and submarines belonging to Indian Navy. An independent audit by veterans is called for.

Reports say a life was lost whilst testing a tank in shipyard. Before testing any tank or pipeline by pneumatic / hydraulic test for integrity, the weld seams ought to be 100% radio-graphed in a non-destructive testing, to look for defects in welds. Only after successful radiography pneumatic / hydraulic test ought to be attempted.

The amount of energy stored in a compressed gas (gases being more compressible than liquids), greatly exceeds the energy stored in a compressed liquid. If a failure of the pipeline were to occur during a high-pressure pneumatic pressure test, the sudden release of this large amount of energy could be dangerous to personnel conducting the tests.

Therefore, the test is to be conducted in a stepped-scale up mode. Again some professional compromises, which played with safety norms and taken a life, giving bad name to Navy, though DRDO appears to be involved, as it has ordered an inquiry. DRDO is a scientific organisation. If test was being conducted under their aegis, then it is deplorable, to say the least.
