The invention relates to a ship containment system for storing and/or transporting liquefied hydrogen, which system comprises a spherical cargo tank arrangement within the ship's hull, wherein (a) the cargo tank is supported by a skirt arrangement mounted on the hull of the ship through which the tank is mounted in the ship without direct contact between outer layer of the cargo tank [4] and the hull, with hold spaces [10] between the cargo tank and the hull, and comprising a structural transition joint [8] between the upper part of the skirt and the lower part of the skirt; and which system is further provided with (b) a pump for loading and discharging the liquefied gas located in a pump tower [1]; (c) a tank cover [2]; (d) a cargo tank insulation layer [3] that is applied to the outer layer of the cargo tank [4]; wherein: the inner side of the ship's hull [6] is provided with an insulation layer [11], covered by an internal lining at the side of the hold spaces [10], being any suitable foil at the vertical sides of the inner hull, and at the sides below the cargo tank on the bottom of the ship's hull structure [9] being a membrane showing minimal expansion and/or contraction under the conditions applied; the hold spaces [10] are filled with an inert gas and are provided with means for managing pressure and means for monitoring temperature; the skirt is mounted on the hull structure with a mounting setup that comprises a insulating layer in between the skirt and the inner side of the inner hull [ 6 ]; and the tank cover (2) is provided with an internal insulation layer [12]. Further, the invention relates to a process for managing insulation of said ship containment system and a process for managing leakages of said ship containment system.
