Abstract
The invention relates to a method for making the wall of a heat-insulated fluid-confinement tank, such as for a liquefied gas, that is integrated in the carrier structure (50) of a ship, wherein a prefabricated substantially rectangular block (25) is assembled on top of a flexible mat strip (35), the assembling of said block comprising the following steps: applying two longitudinal parallel strips of glue (26, 26′) on the lower surface of said block (25), said strips (26, 26′) being separated by a glue-free central longitudinal space (28); gluing said glued block (25) on a flexible mat strip (35) by pressing said glued block (25) on said flexible mat strip (35) so that after gluing, said longitudinal central space (28) is at least partially filled with glue, thus defining a substantially continuous glue layer on the lower surface of the block (25), said substantially continuous glue layer reinforcing the gluing of said flexible mat strip (35) in order to ensure tightness.
