LNG Storage Tanks

The storage tanks at Energía Costa Azul were constructed according to the regulatory requirements in Mexico, which are similar to those in the U.S. and some even more stringent.

The tanks were constructed using a full-containment, engineering design that provides two levels of safety protection. Within the full-containment storage tank, LNG is housed in a climate-controlled container, with extremely efficient insulation, that is analogous to a thermos bottle.

The climate-controlled container is encased inside a second container comprised of pre-stressed concrete.

The full-containment tanks have double walls — an inner wall of 9 percent nickel steel surrounded by a wall of concrete, three feet thick. Should the inner steel wall fail, the outer concrete tanks would contain the LNG.
