Systems and methods for vertical supporting of high pressure gas cylinders

A pressure receptacle support system, comprising:

• a pressure receptacle comprising a central portion disposed along a longitudinal axis, a first end and a second end opposite the first end, the first and second ends being disposed along the longitudinal axis;
• a first end support assembly fastened to the first end, the first end support assembly comprising:
• a ground support;
• and
• a coupler having a receptacle interface at a first end and a rotation interface at or extending from a second end opposite the first end, the receptacle interface being fastened to the first end of the pressure receptacle;
• wherein a sway range for the pressure receptacle is provided by rotation of the rotation interface of the coupler relative to the ground support and relative motion of the second end of the pressure receptacle relative to a portion of a deck of a maritime vessel.

A pressure receptacle support system providing sway control for a pressure receptacle, comprising:

• a first end support assembly configured to couple with a first neck portion of a vertically oriented pressure receptacle, the first end support assembly comprising:
• a ground support comprising a first pivot structure, an elongate body and a free end opposite the first pivot structure, the elongate body configured to extend away from the first neck portion to the free end;
• a coupler having a receptacle boss interface configured to couple with a first boss at a first end and a second pivot structure at or extending from a second end opposite the first end;
• and
• a second end support assembly configured to couple with a second neck portion of a vertically oriented pressure receptacle, the second end support assembly comprising:
• an upper coupler configured to be secured to an upper support structure;
• and
• a spherical member configured to be coupled with an outer surface of a second boss of a pressure receptacle, the spherical member being mounted within and pivotable relative to the upper support structure;
• wherein a range of angulation is provided by rotation of the spherical opening of the coupler over the ball end of the ground support and by sliding of the spherical member along the second boss.

A pressure receptacle comprising:

• a central portion disposed along a longitudinal axis;
• a first neck portion comprising a first boss at a first end of the central portion, the first boss comprising a first array of fastener apertures;
• a second neck portion comprising a second boss at a second end of the central portion opposite the first end, the second boss comprising a second array of fastener apertures;
• and
• a plug sealing one end of a volume disposed within the central portion;
• wherein the second boss comprises a first length configured to be supported by a maritime vessel deck coupler over a first range of positions between an empty condition and a full condition and a second length configured to be supported by a maritime vessel deck coupler over a second range of positions between a full tilted orientation and a full vertical orientation, the full tilted orientation resulting from swaying of the pressure receptacle away from the full vertical orientation relative to a support structure with which the pressure receptacle is coupled.
