WebCargo tank purging and gas freeing. When the tanker is fitted with an inert gas system, the discharged cargo tanks are purged until the hydrocarbon vapors in the cargo tanks have been reduced to less than 2% by volume. Gas freeing may then take place at the cargo tank deck level. For tankers not provided with an inert gas system the flammable ... WebInerting refers to the process of introducing an inert gas into an enclosed space to release the gas already present, resulting in a kind of hazard.
