- the primary waterproofing membrane comprises series of perpendicular corrugations that allow it to deform under the effect of thermal and mechanical stresses generated by the fluid stored in the tank.
- the wave movements to which the ship is subjected have the effect of agitating the liquefied natural gas stored in the tank.
- This agitation creates movements of liquefied natural gas against the walls of the tank that generate dynamic pressure surges, likely to degrade the primary waterproofing membrane, especially if it is not properly supported by the barrier primary thermal insulation.
- An idea underlying the invention is to provide a sealed and thermally insulating tank for storing a fluid which offers excellent resistance to pressure surges which may be generated by the movement of the fluid inside the fluid. tank.

- the reinforcing insulating plug has a structural function of taking up compressive loads which are exerted on the specific area of the waterproofing membrane.
- the reinforcing insulating plug has a layer of polymeric foam.
- Such a tank is advantageous in that the primary thermally insulating barrier is reinforced at a particularly critical zone, namely in an anchoring zone of a primary insulating panel, facing a specific zone of the diaphragm.
- primary sealing which due to its portion protruding inwardly or outwardly of the vessel is particularly sensitive to pressure surges generated by the movement of fluid in the vessel.
- the anchoring device according to the invention bears against the rigid outer plate which is less subject to creep and crushing phenomena than a polymer foam, which makes it possible to ensure satisfactory anchoring of the insulating panel. primary.
- such a tank may have one or more of the following characteristics.
- the polymeric foam layer of the reinforcing insulating plug has a yield strength greater than that of the polymeric foam layer of the primary insulating panel.
- the primary thermally insulating barrier being reinforced locally by the presence of the reinforcing insulating plug, the mechanical characteristics of the polymeric foam layer of the primary insulating panel are less critical, which allows said primary insulating panel to have better characteristics. thermal insulation and / or to be less expensive.
