A number of LNG storage tank designs have been implemented on past and current projects. Such designs include full containment tanks with a 9%Ni inner liner for primary containment and storage of LNG at cryogenic temperature, a carbon steel liner for secondary liquid containment, thermal corner protection and vapor barriers on the inner tank and a concrete outer tank for resistance to external loads.

LNG storage tanks are a key component of an LNG liquefaction or regasification facility and there is only a handful of specialized contractors that possess the tank technology and track record of the materials involved and the construction know how required for successful execution. This paper will focus on factors influencing LNG storage tanks design selection and construction execution strategies which can be a function of functional requirements as well as project location.
