Abstract
The invention relates to an inexpensive technique and procedure to add storage capacity to existing hydrocarbon storage tanks that have a double seal floating roof. The additional storage capacity is obtained by installing an extension that is strong enough to provide the upper seal of the double seal arrangement to maintain a sealed vapor space that allows the roof to move higher within the existing peripheral wall of the storage tank.
