The International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) is an international code of practice developed by the International Maritime Organization (IMO) to ensure the safe transportation of liquefied gases by sea. It sets out detailed standards for the design, construction, and equipment of gas carriers, covering aspects such as:   

• Ship Structure: The IGC Code specifies requirements for the structural integrity of gas carriers, including the hull, bulkheads, and decks.
• Cargo Containment Systems: It outlines the design, construction, and testing of cargo tanks, piping systems, and valves to ensure the safe containment of liquefied gases.
• Safety Systems: The code mandates the installation of various safety systems, including fire protection, gas detection, and emergency shutdown systems.
• Electrical Installations: It sets standards for the electrical systems on gas carriers, including wiring, switchboards, and emergency power sources.
• Crew Accommodation: The IGC Code specifies requirements for the accommodation of the crew, including living quarters, mess rooms, and recreation facilities.
• Emergency Procedures: It outlines emergency procedures for various scenarios, such as fires, explosions, and gas leaks.

By adhering to the IGC Code, gas carriers can minimize the risks associated with the transportation of liquefied gases and protect the marine environment.
