The tanks designated to hold LNG are specially designed to keep the LNG insulated and contained. They consist of an internal layer of 9% nickel steel, followed by an external layer of concrete. Then there is another tank built around this inner tank, as a superior failsafe.

These tanks meet world-class safety standards, and the Canadian Standards Association's requirements for natural gas storage.

At Canaport LNG, the LNG will be stored in above ground
full containment tanks. A full containment tank consists
of a inner tank, the principal storage compartment, composed of 9% nickel steel.

The inner tank is surrounded by a reinforced concrete outer tank consisting of a pad, pre-stressed walls and a reinforced concrete roof lined with carbon steel. The outer tank is designed to hold the entire contents of the inner tank and allow for a controlled venting of vapors in the event of leakage from the inner tank.
