Abstract
A pressure vessel is provided including a housing capable of withstanding external hydrostatic pressures having an internal cavity defining a first opening permitting access to the internal cavity. A plug is disposed in a plug region near the first opening. A gland seal is disposed adjacent to the plug and a piston is disposed adjacent to the gland seal. A first and second plate connected via one or more rods are disposed adjacent to the piston. A tightening mechanism is configured to exert force against the gland seal such that expansion of the gland seal seals the first opening. A casing is disposed over an outer surface of the housing, the plug, the gland seal, and at least a portion of the piston.
