Abstract
Watertight and thermally insulating tank built into the bearing structure of a ship, the said tank comprising two successive watertightness barriers, the said bearing structure comprising walls (1) which form the internal sides of its double hull and two transverse bulkheads (2), these two watertightness barriers alternating with two thermally insulating barriers, the corner connection of the elements of the primary and secondary barriers, in the zones where the transverse bulkheads meet the internal sides, being achieved in the form of a connecting ring, the structure of which remains substantially constant right along the solid angle (3) of intersection between a transverse bulkhead and the internal sides, each connecting ring comprising a prefabricated composite girder (20) consisting of a rigid metal formwork (21) incorporated in a thermally insulating material (22), the said rigid formwork defining a central fixed anchorage zone (29) substantially at the intersection between the plane that bisects the connecting corner and the extension of the secondary watertightness barrier, for its mechanical connection to the said central anchorage zone, the opposite ends (23) of the said …
