Abstract
A sealed and insulating tank for storing and/or transporting a liquefied gas has a sealed and self-supporting internal reservoir with an interior surface for contacting the liquefied gas and an outer surface with an insulating barrier covering the outer surface of the internal reservoir. The insulating barrier is fixed to the internal reservoir. An outer sealed membrane covers an outer surface of the insulating barrier, and the outer sealed membrane has a metal sheet provided with bellows or corrugations. The outer sealed membrane is fixed to the insulating barrier or the internal reservoir. An intermediate space between the internal reservoir and the outer sealed membrane contains a gaseous phase under depression in order to press the outer sealed membrane against the outer surface of the insulating barrier.
