What Is An Inert Gas System (IGS) On Ships Tankers?

2021-4-16  Inert Gas System (IGS) on a ship refers to a system deployed for the prevention of an explosion in the cargo tanks of a tanker. In this integrated system, while pumping out the liquid inflammable cargo, an inert gas (sometimes by flue gas from ship boilers) is also pumped in. An oil tanker’s job is to carry different types of oil that vary in ...
