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.

Illustration of an LNG Storage Tank

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.
