Abstract:
A vessel for transporting liquefied natural gas is provided. The vessel generally includes a gas transfer system for on-loading and off-loading natural gas to and from the vessel at essentially ambient temperature. The vessel further includes a gas processing facility for selectively providing liquefaction and regasification of the natural gas. The vessel also includes a containment structure for containing the liquefied natural gas during transport. The vessel may be a marine vessel or a barge vessel for transporting LNG over water, or a trailer vessel for transporting LNG overthe-road. A method for transporting LNG is also provided, that provides on-loading of natural gas onto a vessel, condensing the natural gas, storing the gas on the vessel in liquefied form, transporting the gas to an import terminal, vaporizing the gas, and off-loading the gas at the terminal.
Abstract:
A method of making a cylindrical pressure vessel (11) with a large diameter port in its sidewall includes the step of providing a mandrel (23) of desired diameter and filament winding upon the same. After winding one overall innermost layer, an annular reinforcement belt (16) is helically wound atop a defined region using a band (60) of resin impregnated parallel strands (39) under tension. The annular belt (16) is then itself helically overwound with the resin impregnated parallel strands of filamentary material under tension to provide two complete outer layers. After curing and removal from the mandrel (23) at least one aperture (71) is cut in the sidewall within the reinforcement belt (16) and a side port fitting (75) is installed in the aperture (71).
Abstract:
Containers suitable for storing pressurized fluids at cryogenic temperatures of −62° C. (−80° F.) and colder are provided and comprise a self-supporting liner and load-bearing composite overwrap, whereby means are provided for substantially preventing failure of the container during temperature changes.

Abstract:
An anti-pressure system for a vessel which is subject to internal pressure created by heating or boiling of its contents, the system comprising first and second spaced-apart outlets for vapour to exit the vessel, each outlet having a first side communicating with the vessel interior and a second side communicating with the vessel exterior. The invention provides a reliable method of protecting a normally un-pressurized vessel, such as an autoclave, distillation vessel, boiler or the like, from dangerous pressure build up, resulting from its vapour outlet being blocked, regardless of what other pressure release devices (if any) may be present on the vessel.
Abstract:
A vessel (50) having a cylindrical wall (52) and an end wall (54). The cylindrical wall (52) includes an edge portion (58), a radially inward shoulder portion (60), and a capture portion (62) therebetween. The end wall (54) is interference-fit in the capture portion (62) with the shoulder portion (60) forming a positive stop therefore and the edge portion (58) being turned radially inward thereover. An inlet/outlet fitting (70) extends through an appropriately-sized opening in the end wall (54) and is secured thereto by, for example, a lip (72) and a weld (74). The vessel (50) can be incorporated into the construction of refrigeration components wherein compressor-generated vibration causes stress concentration concerns for inlet/outlet interfaces on the end wall (54).
Abstract:
A reservoir of the device supports, in its upper portion, a profiled flange forming a handling apparatus for the device and a trough to collect and discharge, via an opening, the water of condensation forming on a vaporization coil. The coil has turns of changing diameters, supported by support combs on the trough and enclosed in a cover provided with peripheral and upper air openings. The cover includes an element for securing a receptacle that directly coacts, by gravity, condensates.
Abstract:
Methods and apparatus for filling containers with a gas or gas mixture under pressure are disclosed. The apparatus comprises a fixed volume vessel for containing the gas at a pressure P.sub.1, a line extending from the fixed volume vessel to a buffer volume vessel which has a capacity greater than the volume of the container to be filled, a pressure controller for controlling the pressure of the gas in the line so that the gas reaches the buffer volume vessel at a pressure P.sub.2 which is less than P.sub.1, a further line extending from the buffer volume vessel to at least one filling nozzle, and a valve located in the further line for controlling the flow of gas from the buffer volume vessel to the gas capsule to be filled.
Abstract:
A capsule for storing a fluid, for example helium, under pressure comprises a hollow body from which extends a hollow neck. A stopper engages with the neck in a fluid tight manner. The stopper includes a main hollow portion and a stem extending outwardly from the main hollow portion. The root of the stem where it joins the main hollow portion forms a frangible section which, when broken, will allow fluid in the capsule to escape under pressure.
Abstract:
An inflator and method of constructing the inflator comprising: a pressure vessel (22) in which inflation gas is stored; the pressure vessel including a first opening (114), pyrotechnic generator (42, 130) situated remote from the pressure vessel for generating products of to heat the inflation gas, a first burst disk (160, 150, 150') mounted to the pressure vessel to seal the first opening thereof after the pressure vessel has been charged to a determinable pressure with inflation gas and in communication with the pyrotechnic generator such that the products of combustion assist in the opening of the first burst disk.
