Summary:The present invention relates to a tank (21) for transporting and/or storing a liquefied gas. The tank comprises a plurality of walls, each comprising, in a direction of the thickness of the wall, a thermally insulating barrier and at least one leak-tight membrane that rests against the thermally insulating barrier and is intended to be in contact with the liquefied gas inside the tank (21), the thermally insulating barrier comprising a plurality of self-supporting heat-insulating panels which each comprise a block of polymer foam and at least one plate, a bottom wall (27) of the plurality of walls comprises at least one first portion (29) at least partially surrounding a second portion (31) of the bottom wall (27), the second portion (31) comprising at least one drain, characterized in that the blocks of polymer foam of the second portion (31) have a density greater than a density of the polymer foam blocks of the first portion (29). La presente invención se relaciona con un tanque (21) para transportar y/o almacenar un gas licuado. El tanque comprende una pluralidad de paredes, cada una comprendiendo, en una dirección del grosor de la pared, una barrera térmicamente aislante y al menos una membrana hermética que se recarga contra la barrera térmicamente aislante y está destinada a quedar en contacto con el gas licuado dentro del tanque (21), la barrera térmicamente aislante comprendiendo una pluralidad de paneles de aislamiento térmico de autosoporte que comprenden, cada uno, un bloque de espuma de polímero y al menos una placa, una pared de fondo (27) de la pluralidad de paredes comprende al menos una primera porción (29) rodeando al menos parcialmente una segunda porción (31) de la pared de fondo (27), la segunda porción (31) comprendiendo al menos un desagüe, diferenciándose porque los bloques de espuma de polímero de la segunda porción (31) tienen una densidad mayor que una densidad de los bloques de espuma de polímero de la primera porción (29).
