The invention relates to a valve system of a fuel tank, especially of an LNG tank, which valve system includes at least two pressure relief safety valves, in which valve system one pressure relief safety valve is located in one safety valve branch branching from an outlet line from the LNG tank. The valve system further comprises interconnected shutoff valves for shutting off one of the safety valve branches at time and that the shutoff valves are diverter valves with a T-bore.

A fuel storage and distribution system for a gas-fueled sea-going vessel includes a tank room that constitutes a gastight space enclosing tank connections and valves associated with them. A part of a refrigeration or air conditioning circuit reaches into the tank room. A first local heat transfer circuit is configured to receive heat from the part of the refrigeration or air conditioning circuit in the tank room and arranged to transfer such received heat to liquefied gas fuel handled in the fuel storage and distribution system.

A cryogen storage vessel at an installation is filled with liquid cryogen from a liquid cryogen storage tank that has a pressure lower than that of the vessel. After headspaces of the vessel and tank are placed in fluid communication with another via a gas transfer vessel and are pressure-balanced, a pump in a liquid transfer line connected between the tank and the vessel is operated to transfer amounts of liquid cryogen from the tank to the vessel via the liquid transfer line and pump as amounts of gaseous cryogen are transferred, through displacement by the pumped cryogenic liquid, from the vessel to the tank.

An arrangement for a cryogenic system includes a cryogenic tank for storing a cryogenic liquid and a trycock pipe, which trycock pipe has a first end mechanically connected to the cryogenic tank. The trycock pipe includes a tube with a first end fluidly connected to the cryogenic tank for receiving cryogenic liquid from the cryogenic tank. The arrangement further includes a sensor measuring the temperature of the tube. The tube has a second free end opposite to the first end of the tube, which second free end is closed, and the temperature sensor is arranged outside the tube measuring the temperature at the second free end of the tube.

A pressure accumulator includes a cylindrical body made of metal and configured to vaporize and store a liquefied gas in a storage space in the cylindrical body, a lid body having a through hole that allows a pipe to penetrate through the through hole, and being configured to close an opening end portion of the cylindrical body with a gap between the lid body and an inner peripheral surface of the cylindrical body, a sealing structure portion between an outer peripheral portion of the lid body and an inner peripheral portion of the cylindrical body, and a fixing part at the opening end portion of the cylindrical body, an outer peripheral surface of the fixing part being screw fastened to the inner peripheral surface of the cylindrical body to support and fix the lid body from an outer side of the lid body.

A low temperature fluid dual structure pipe includes: an inner pipe through which a low temperature fluid flows; and an outer pipe externally fitted to the inner pipe with a sealed tubular space therebetween. An inactive gas having a melting point and a boiling point each of which is equal to or higher than a temperature of the low temperature fluid is filled in the tubular space between the inner pipe and the outer pipe. When the low temperature fluid flows through the inner pipe, the inactive gas is liquefied or solidified, and therefore, at least one of a liquefied inactive gas layer and a solidified inactive gas layer is formed on an outer peripheral surface of the inner pipe. As a result, a pseudo vacuum layer that is in a substantially vacuum state is formed in the tubular space.

A device for fueling motor vehicles with a fluid used as a fuel and composed of liquefied gas, in particular liquefied natural gas, includes: at least one storage container; a cooling device; at least one conveying device for feeding the fluid from the at least one storage container to at least one fueling device for motor vehicles; and at least one line for supplying the fluid to the fueling device. The at least one line includes a media-conveying central pipeline as a medium pipe and at least one additional media-conveying pipeline that is arranged concentrically with respect to the central pipeline and defines an annular space together with the media-conveying central pipeline. The media-conveying central pipeline and the at least one annular space supply and return the fluid or a gas flow. The at least one additional media-conveying pipeline is surrounded by a jacket pipe.

A sealed and thermally insulating tank for storing a fluid, the tank being anchored in a load-bearing structure, the tank having a loading/unloading tower suspended from a ceiling wall of the load-bearing structure, the tank having a support foot that is fastened to the load-bearing structure in a zone of a bottom wall of the tank, the support foot being arranged to guide a vertical translational movement of the loading/unloading tower, the tank having at least one sump that is formed in the bottom wall of the tank, the bottom wall of the tank having a corrugated sealing membrane that is intended to be in contact with the fluid having at least first corrugations extending in a first direction and spaced apart from one another, the sump and the support foot are spaced apart by a distance at least three first corrugations pass between the sump and the support foot.
