The International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk, commonly known as the IGC Code, is a comprehensive set of international guidelines established by the International Maritime Organization (IMO). The primary focus of the IGC Code is to ensure the safe construction, equipment, and operation of ships engaged in the transport of liquefied gases in bulk. This code is crucial in preventing accidents, minimizing the risks associated with the carriage of liquefied gases, and safeguarding the lives of seafarers and the marine environment.


The IGC Code was first adopted by the IMO in 1971, with the initial edition entering into force in 1976. Subsequent amendments and updates have been made to the code to address evolving safety concerns, technological advancements, and lessons learned from incidents involving the transportation of liquefied gases. The code is regularly revised to stay current with industry developments and to enhance safety standards.

Contents within the Code:

The IGC Code is structured to cover a wide range of aspects related to the safe transportation of liquefied gases. Some key elements within the code include:

  1. Design and Construction Standards: The code provides detailed specifications for the design and construction of ships carrying liquefied gases, ensuring that vessels are built to withstand the unique challenges posed by the carriage of these substances.

  2. Equipment Requirements: The IGC Code outlines specific equipment standards to be met by ships, including cargo containment systems, pressure-relief systems, and instrumentation, to guarantee the safe handling of liquefied gases.

  3. Operational Procedures: It includes guidelines for the safe operation of ships during loading, unloading, and transportation of liquefied gases. This encompasses procedures for cargo transfer, monitoring, and emergency response.

  4. Safety Measures: The code incorporates safety measures to prevent and mitigate potential hazards, such as fire and explosion risks, associated with the carriage of liquefied gases.

  5. Training and Certification: The IGC Code mandates training requirements for the crew, ensuring that personnel are adequately prepared to handle the complexities of transporting liquefied gases. Additionally, it establishes certification standards for the ships and their equipment.

  6. Documentation and Record-Keeping: The code requires the maintenance of appropriate documentation and records related to the construction, equipment, and operation of ships carrying liquefied gases.

In summary, the IGC Code serves as a crucial regulatory framework, setting standards for the safe transport of liquefied gases by sea. It reflects the international maritime community’s commitment to promoting safety, preventing accidents, and minimizing environmental risks in the transportation of hazardous cargoes.
