A pressure vessel closing system for conducting industrial processes has a pressure vessel with an underside door opening having a major and a minor axis, a cover that is proportionally larger than the door opening, and an external door operating mechanism. The door operating mechanism has door manipulation capabilities for inward movement, rotation, lateral movement, tilting movement, and outward movement of the cover into and out of the pressure vessel through the door opening, for internally closing the door against the inner face of the door opening; the door being then self sealing from the pressure applied within the pressure vessel.
