Abstract
A method and apparatus for pressure testing a large vessel utilizing a base enclosure having a base ring of the same diameter as the pressure vessel. The base enclosure includes a base plate welded to the base ring and beams under the base plate for supporting the weight of the base enclosure as well as the portion of the vessel to be tested. The vessel is fabricated in or divided into half portions with each portion being connected to a base ring for separate testing. This eliminates the excessive weight that would be experienced if the vessel were to be pressure tested as one unit, particularly in the case of hydrotesting where the vessel is filled with water.
