Abstract

The vent cap system for a suction pile includes a top plate, a center stem assembly, a bottom plate, a flange assembly, and perimeter stem assemblies. The bottom plate moves between an opened position and a closed position. The center stem assembly is in direct threaded engagement with the top plate, and the perimeter stem assemblies and stem retainer cooperate to maintain alignment of the bottom plate. A pipe plug to test the sealing engagement is placed on the bottom plate, instead of the flange assembly. There is a closing lip of the bottom plate so that a sealing diameter can be the smallest diameter of the flange assembly, which reduces force on the bottom plate from under the bottom plate. There is a connection portion of the flange assembly to attach the system to the suction pile so that weld deformation does not affect the entire flange assembly.
