Abstract: A tank that has a tank wall having a secondary insulating barrier, a primary insulating barrier, a primary sealed membrane and a secondary sealed membrane, the tank wall having a first area in which the insulating modules include spacers extending in a thickness direction of the tank wall between a cover panel and a bottom panel of said insulating modules, a second area in which a cover panel of the insulating modules is kept at a distance from a bottom panel by a structural insulating foam, a transition area interposed between the first area and the second area, the transition area having a coefficient of thermal contraction and/or a modulus of elasticity in the thickness direction of the tank wall which is between that of the first area and that of the second area.

Abstract: An internal bottom wall of the double hull bears a sump structure comprising a rigid container arranged through the thickness of the bottom wall of the tank and intended to accommodate a suction member of a pump. The rigid container comprises a bottom wall situated at a level further toward the outside than the secondary sealing membrane of the bottom wall of the tank. The sump structure comprises a primary connecting plate surrounding the container, the primary connecting plate having a connecting surface extending parallel to the primary sealing membrane of the bottom wall of the tank, the primary sealing membrane of the bottom wall of the tank being attached in a sealed manner to the connecting surface all around the sump structure.
