Storage and Transport
During the past 50 years, LNG carriers have traveled over 128 million miles without a significant accident.
LNG is transported via double-hulled tankers which are specially designed and insulated to prevent leakage or rupture in an accident. These vessels contain primary and secondary cargo containment systems that prevent leaks as well as sophisticated equipment to enhance safe navigation.
On land, LNG is stored at atmospheric pressure in specially engineered and constructed double-walled storage tanks. Most of these tanks have three-foot concrete exterior walls and an inner tank that is constructed from a steel-nickel metal alloy specifically designed to accommodate the cold LNG. Should a leak develop in the inner wall, all of the LNG would be contained by the outer walls. Sophisticated monitoring systems provide constant surveillance for any internal leaks.
LNG is converted back into natural gas by pumping the fluid from the storage tank and heating it to re-gasify the liquid. The gas is then ready for delivery through natural gas pipelines to homes and businesses.
