The following article is about the analysis of different Inert Gas Systems, both used in marine practice and those that are not widely implemented. These systems are designed for supplying the cargo tanks of oil tankers and chemical tankers with inert gas in order to reduce the concentration of oxygen to the levels, at which the combustion is not possible. Because of this systems and their use on ships the amount of incidents connected to cargo operations is approaching zero. In this article those systems are analyzed, compared, including their advantages and disadvantages. One of the most important factors is gas supply, type of supply, as it is directly connected to cargo operations and their speed.
