A ship or floating support for carrying or storing liquid consisting of a liquefied gas, preferably chosen from methane, ethylene, propane, and butane, cooled in a large tank that is preferably cylindrical and of polygonal cross-section, that is thermally insulated, and of large size with at least its smallest dimension in the horizontal direction, in particular its width, being greater than 20 m and preferably in the range 25 m to 50 m, and presenting a volume greater than 10,000 m3 the reservoir is equipped with at least one attenuation device for attenuating movements of the liquid and having a mechanism for moving the liquefied gas liquid inside the reservoir so as to form a horizontal stream immediately below the free surface of the liquefied gas at least locally over a depth of at least 0.5 m, and preferably at least 2 m. |
