Abstract:
Watertight and thermally insulating tank built into the bearing structure (1, 2) of a ship, the 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, thermal insulation consisting of a thermally insulating barrier only located between the secondary watertightness barrier and the walls of the bearing structure and substantially no thermal insulation between the primary and secondary watertightness barriers, said tank comprising an impact-resistant mechanical protecting shield (16) located between the two watertightness barriers (13, 17), the shield (16) being held elastically pressed against the secondary watertightness barrier (13) by metal fastening means (12) mechanically connected to the insulating barrier (4, 104).
