Ship containment system for liquified gases

Abstract

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) thecargo 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.

Description

technical field [0001] The invention relates to a ship containment system for storing and / or transporting liquefied hydrogen and a marine transport vessel comprising said containment system. Furthermore, the invention relates to a method for managing the thermal insulation of said containment system and its leakage. Background technique [0002] Hydrogen is an important industrial gas used in the oil refining and fertilizer industries, as well as in several other chemical processes. Hydrogen is also expected to play an important role as an energy carrier, especially in the field of transportation. [0003] Generally, for short distances, gas can be transported via pipelines by means of pressure. For long distances, the gas is usually transported by means of ocean transportation. In the absence of suitable pipeline networks for gaseous hydrogen and for import purposes, hydrogen in liquid form is expected to be one of the most efficient means for its supply and distribution...
