    Abstract: A boss assembly for a pressure vessel includes a boss, a fitting, a first seal and a second seal. The boss includes a bore with an inner surface and a first stop feature. The fitting is configured for at least partial insertion into the boss to prevent fluid communication between an interior and an exterior of the pressure vessel, the fitting including an outer surface and a second stop feature. Each of the first and second seals is positioned along the outer surface. The fitting is movable between first and second positions. In the first position, the first seal is sealingly engaged between the inner and outer surfaces and the second seal is not sealingly engaged therebetween. In the second position, the first seal is not sealingly engaged between the inner and outer surfaces, the second seal is sealingly engaged, and the first and second stop features mutually contact.

    Abstract: A system includes a source of pressurized fluid, a primary pressure vessel disposed in fluid communication with the source, and a supplemental pressure vessel disposed in fluid communication with the source and in fluid communication with the primary pressure vessel. The primary pressure vessel has a first life expectancy duration and includes a first structural characteristic. The supplemental pressure vessel has a second life expectancy duration shorter than the first life expectancy duration and includes a second structural characteristic. A method uses a supplemental pressure vessel to predict impending failure of a primary pressure vessel. The method includes connecting a primary pressure vessel to a source of pressurized fluid, fluidly connecting a supplemental pressure vessel with the source and with the primary pressure vessel, and exposing the supplemental pressure vessel to a first fatigue load to cause its failure before failure of the primary pressure vessel occurs.

    Abstract: A sensor mounting assembly is configured for use with a vessel arrangement including at least four vessels. The assembly includes first and second elongated frame members, first and second rollers, and first and second sensors. The first sensor is attached to the first elongated frame member and is configured to contact the surface of the first vessel upon actuation in a first direction. The second sensor is attached to the second elongated frame member and is configured to contact the surface of the second vessel upon actuation in a second direction that is substantially orthogonal to the first direction. This disclosure also describes a method of mounting at least six sensors for use with a vessel arrangement including at least four vessels, the vessel arrangement disposed in a container in a two-by-two stacked configuration having a central space.

    Abstract: A boss configured for attachment to a pressure vessel includes a first bore therein and a bearing disposed at least partially within the first bore. A system for supporting a pressure vessel on a vessel mount includes a boss, a bearing, and an attachment element. The boss is attached to the pressure vessel and has a first bore therein. The bearing is disposed at least partially within the first bore and has a second bore therethrough. The attachment element is configured to be affixed to the vessel mount, wherein a portion of the attachment element extends through the second bore and is slidable within the first and second bores substantially along a longitudinal axis of the pressure vessel. A method is described for supporting a pressure vessel on a vessel mount.

    Abstract: A pressure vessel has an interior chamber and includes an outer shell, a boss, and an internal liner disposed within the outer shell. The boss includes a port extending between the interior chamber and an exterior of the pressure vessel; and an annular flange extending radially from the port and having an exterior surface and an interior surface. The liner includes an exterior portion adjacent the exterior surface of the flange; an interior portion adjacent the interior surface of the flange; and a vent in the interior portion. A method for forming a pressure vessel includes mounting a boss on a mandrel, flowing a non-metallic polymer around a flange of the boss to form an internal liner of the pressure vessel, forming a vent in an interior portion of the liner; and forming an outer shell surrounding the liner and at least a portion of the flange of the boss.

    Abstract: A system includes a first valve fluidly connected to a first vessel and a second valve fluidly connected to a second vessel. The first valve includes a body and a piston. The body includes first and second ports and a bore having a longitudinal axis. The first port is in communication with the bore and an interior of the first vessel. The second port is in communication with the bore, the second valve, and an atmosphere exterior to the first vessel. The piston is movable along the longitudinal axis of the bore. A first position of the piston blocks the first port; a second position of the piston allows fluid communication between the first and second ports. The first valve is configured so that fluid pressure from the second valve, communicating through the second port, urges the piston to the second position.
