Gas carrier standards


The design standards defined by the International Gas Carrier Code (IGC Code). Depending upon the degree of hazard presented by the products to be carried, gas carriers should be designed according to one of the following standards: – type 1G ship, – type 2G ship or type 2GP ship, – type 3G ship. Thus, a type 1G ship is a gas carrier intended for the transportation of products of the greatest overall hazard and types 2G/2GP and type 3G for products of relatively lower hazards. Accordingly, a type 1G ship should survive the most severe damage and its cargo tanks should be located at the maximum prescribed distance inboard from the shell plating.
