Can LNG leak from a storage tank?
There are numerous layers of robust safety and security systems in place to prevent any such incidents. There are also monitoring systems in place to quickly detect a leak and trigger the safety systems. Storage tanks are built with multiple layers of containment. There is an external dike around the tank designed to contain its entire contents. Beyond this dual containment system required by federal regulations, many modern tanks have two walls – an inner wall of high nickel steel surrounded by a wall of concrete, generally three feet thick. Should the inner steel wall fail, the outer concrete tanks will contain the LNG. Here’s a picture of tanks which are similar to those Oregon LNG will be building at the site.
