FOLLOWUP Navy has launched a probe into the mishap on board INS Sindhuratna to figure out what led to smoke on the submarine. According to reports, around 240 lead acid batteries could be the reason for the smoke that engulfed many chambers of the submarine.
According to experts, batteries are changed in a refit since old batteries emit more hydrogen. But, in this case, submarine underwent a refit but the batteries were reportedly not changed.
The maximum amount of hydrogen gas is emitted while batteries are being charged but its levels are strictly monitored by duty—watch sailors. Hydrogen leakage can cause problems but there is a system to discharge the gas," said one expert.
INS Sindhuratna was forced to surface after the smoke was detected in its third compartment.
"The maximum amount of hydrogen gas is emitted while batteries are being charged but its levels are strictly monitored by duty—watch sailors. Hydrogen leakage can cause problems but there is a system to discharge the gas. The BoI actually will come out with the actual reason," said another source.
