The LNG brought to the Canaport LNG Terminal is stored in specially designed LNG storage tanks that are insulated to keep the LNG cold and contained until it is regasified. They consist of an inner shell of 9% nickel steel, an interstitial space filled with insulation followed by an external outer shell of concrete and a roof made of reinforced concrete with a carbon steel liner. The outer shell is designed to hold the entire contents of the inner tank and allow for a controlled venting of vapours.

These full containment tanks meet world-class safety standards, and particularly the Canadian Standards Association's (CSA) requirements for liquid natural gas storage tanks.
