Compensated Gross Tonnage (CGT) was introduced by the OECD in 2007 as a unit of measurement that would objectively reflect the relative production capacity in various shipyards and in different regions of the world. The CGT value is calculated for specific types of ships, not for all floating objects.
Ships of similar volume (that is to say, of similar dimensions) will have a very similar Gross Tonnage (GT) value. However, the utilization of the ship’s available volume resulting from the ship’s type may differ significantly. The more complex unit will have a higher CGT value than the less complex unit.
It is worth remembering this rule when analyzing global ship production reports.
