摘要:
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.

Herein a floating vessel is disclosed. The floating vessel comprises a deck member and a tank for liquefied hydrocarbon gas such as LNG. The tank extends through the deck member, and the tank is supported by the deck member, suspended at less than 1/3 of a total height of the tank, seen from the top of the tank.
摘要:
A ship utilising gas as a fuel, the ship including a tank space (580) holding at least one gas storage tank (590), the tank space being open on one side (582), the open side extending from said tank space to the open air outside said ship for allowing the venting of gas in the event of a leak from said gas storage tank held in said tank space, the ship further including a gas consumer (500) in a gas consumer room (505), wherein the gas consumer room and tank space collectively provide only one potentially hazardous ventilation point outside the ship per tank space.
摘要:
In accordance with the present invention there is provided a vessel for the transportation of liquefied natural gas or liquefied CO 2 comprising at least one cryogenic container mounted to the open deck of the vessel and means for transporting liquefied natural gas or liquefied CO 2 into or out of the cryogenic container.

A process is disclosed for unloading a plurality of containers (1, 2) having pressurized liquefied gas contained therein. A pressurized displacement gas (10) is fed to a first container or group of containers to discharge the liquefied gas therefrom. The displacement gas is then withdrawn from the first containers or group and is separated into a first vapor stream and a second vapor stream. The first vapor stream is heated (52) and passed to the first container or group. The second vapor stream is fed to a second container or group to discharge liquefied gas therefrom. Communication between the first container or group and the second container or group is severed and the foregoing steps are repeated for all of the containers in succession, with only the last container or group emptied of liquid remaining at the pressure of the displacement gas, and all of the containers at the end of the process except the last container or group being filled with a lower pressure vapor.

摘要:
A vessel comprising spherical tanks (2) and a production plant for production of gas and possibly oil at sea, wherein the spherical tanks (2) are arranged in a row in the vessel's longitudinal direction and arranged for storage of liquefied natural gas, and the section (1) of the vessel's deck which is located at the spherical tanks (2) extends under the top thereof. In the vessel according to the invention the deck section (1) extends closer to the spherical tank's (2) top sections than to the spherical tank's (2) centres.
摘要:
The present invention relates to a method for tanker, preferably parcel tanker, construction. According to the invention the method comprises the steps of: - providing a hull having arranged therein at least one hold which is accessible via a hatch opening; - providing at least one self-contained tank module comprising a number of cargo tanks; and - arranging in the hold the self-contained tank module to provide a tanker, wherein the tank module is arranged in the hold such that the tank module and the hull are structurally independent and such that the tank module is removable via said hatch opening of the hold after a period of use of the tanker.
