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
