A pressure vessel assembly includes a pressure vessel including a cylinder, a first side dome provided at one end of the cylinder, and a second side dome provided at the other end of the cylinder, a first protector that surrounds an outer surface of the first side dome, a second protector that surrounds an outer surface of the second side dome, and a connector that connects the first protector and the second protector such that the pressure vessel is interposed between the first protector and the second protector. The pressure vessel assembly can help to prevent damage and breakage of the pressure vessel caused by external impact and improve safety and reliability of the pressure vessel.

Disclosed is a re-liquefying device using a boil-off gas as a cooling fluid so as to re-liquefy the boil-off gas generated from a liquefied gas storage tank provided in a ship. A boil-off gas re-liquefying device for a ship comprises: a multi-stage compression unit for compressing boil-off gas generated from a liquefied gas storage tank; a heat exchanger in which the boil-off gas generated from the storage tank and the boil-off gas compressed exchange heat; a vaporizer for heat exchanging the boil-off gas cooled by the heat exchanger and a separate liquefied gas supplied to a fuel demand source of a ship, and thus cooling the boil-off gas; an intermediate cooler for cooling the boil-off gas that has been cooled by the heat exchanger; and an expansion means for branching a part of the boil-off gas, which is supplied to the intermediate cooler, and expanding the same.

A device for transferring a fluid from a supply tank to a receiver tank includes at least one duct for charging the receiver tank with liquid and at least one duct for return of the gas. The gas return duct is configured to transfer the gas contained in the receiver tank at a pressure close to or significantly different from the pressure of the supply tank.

Sealed and thermally insulating tank incorporated into a polyhedral bearing structure, the tank having a plurality of tank walls, a thermally insulating barrier and a sealed membrane, a first bearing wall and second bearing wall forming an edge corner, the thermally insulating barrier of a first tank wall having a row of edging blocks, a row of anchor strips anchored to the second bearing wall by a row of anchor rods, a first and second of edging blocks each having a groove formed in thickness of said edging block, a first and a second of said anchor rods being housed respectively in the groove of the first and second edging blocks, one anchor strip in the row of anchor strips is supported overlapping the first edging block and the second edging block, the anchor strip being coupled to the first anchor rod and to the second anchor rod.

A refuelling device for supplying liquefied gas is provided, including a feed system adapted to place each reservoir in fluidic through connection with a tank and including withdrawal ducts for withdrawing the liquefied gas from the reservoirs; an inlet duct for introducing the liquefied gas into the tank; a collection manifold for conveying the withdrawal ducts into the inlet duct; a pump adapted to move the liquefied gas in the feed system; and a pressure gauge to measure the inlet pressure of the liquefied gas in the pump; and a valve adapted to regulate the flow in the inlet duct according to the inlet pressure.

In one aspect the present disclosure relates to a method of manufacturing a cryogenic pressure vessel. The method may include providing a metal lined, composite wrapped vessel which has a boss. The method may further include securing an inlet to the boss, and then encapsulating the metal lined, composite wrapped vessel within a metallic layer in a vacuum controlled environment to form an encapsulated inner tank subassembly. The method may further include securing at least one support to an exterior of the encapsulated inner tank subassembly, and within the controlled vacuum environment, applying a metal coating over the encapsulated inner tank subassembly and the at least one support to form a metal coated, encapsulated inner tank subassembly. The method may further include, within the controlled vacuum environment, encapsulating the metal coated, encapsulated inner tank subassembly within a metallic vacuum jacket, which forms the cryogenic pressure vessel.
