Abstract
Watertight and thermally insulating tank built into the bearing structure (1) of a ship, the said tank comprising two successive watertightness barriers, one of them a primary one (17) in contact with the product contained in the tank, and the other a secondary one (13) located between the primary watertightness barrier and the bearing structure, a thermally insulating secondary barrier (4) being located between the secondary watertightness barrier and the walls of the bearing structure, characterized in that it comprises an impact-resistant mechanical protecting shield (16) located between the two watertightness barriers, the shield being held elastically pressed against the secondary watertightness barrier by metal fastening means mechanically connected to the secondary insulating barrier, thermal insulation being afforded only by the secondary insulating barrier.
