What happens if an LNG tank fails?
Should a tank ever fail and a leak result, fire is possible, but only if there is both the right concentration of LNG vapor in the air and a source of ignition. Since such a combination rarely exists, explosions are highly unlikely. According to the Federal Energy Regulatory Commission (FERC), “LNG is not explosive. Although a large amount of energy is stored in LNG, it cannot be released rapidly enough to cause the overpressures associated with an explosion.” FERC adds, “LNG vapors (methane) mixed with air are not explosive in an unconfined environment.” LNG ships have emergency shutdown systems that can identify potential safety problems and shut down operations. They prevent or significantly limit the amount of LNG that could be released. Fire and gas detection and fire fighting systems help to address the risk of fire. The detection equipment is so sensitive that it can detect leakage through a hole the size of a pinhead. Special operating procedures, training, and maintenance furt
