Gas carriers

Gas carriers are specialized ships designed for the transportation of natural gas in its liquefied (LNG) or compressed (CNG) state. They are essential to the global energy supply chain, bridging the distance between gas production facilities and consumer markets. Gas carriers are equipped with sophisticated containment systems and safety measures that cater to the unique properties and handling requirements of natural gas.

In their liquefied form, natural gas is cooled at cryogenic temperatures (approximately -162°C), which significantly reduces its volume, making LNG carriers an efficient means of transport over long distances. These vessels have insulated cargo tanks capable of maintaining the low temperatures needed to keep natural gas in a liquid state. LNG carriers are also outfitted with advanced navigation and monitoring systems to ensure safe transit and delivery.

Alternatively, CNG carriers transport natural gas under high pressure, though this method is less common due to technological constraints and efficiency factors. These ships are built with robust, cylindrical pressure vessels designed to safely contain the compressed gas.

Gas carriers play a critical role in facilitating international trade and contribute to the fluidity and flexibility of natural gas supply globally. They make it possible for regions lacking indigenous natural gas resources to rely on imports and help balance supply and demand across different markets.

To learn more about gas carriers and their role in the energy sector, you can visit the following resources:

1. International Gas Union (IGU) – The IGU is a global association that advocates for gas as an integral part of a sustainable global energy system. They provide in-depth information on various topics related to gas transportation, including LNG and CNG carriers.


2. The Society of International Gas Tanker and Terminal Operators (SIGTTO) – SIGTTO is an organization dedicated to the industry’s best practices and safety standards for gas carriers and terminals. Their site offers resources, publications, and industry insights related to LNG and LPG (Liquefied Petroleum Gas) shipping.
