The heavy duty a vent cap system includes a top plate with a bucket interface, a center stem assembly, a retainer assembly, a bottom plate with a stem sleeve and guiding device, an adapter ring, a plurality of perimeter stem assemblies and a plurality of perimeter installation stems. A remote operated vehicle engages the bucket interface to rotate a center stem member in the center stem assembly. A threaded portion of the center stem assembly engages a stem nut in the retainer assembly. The rotation along threads of the stem nut held within the retainer assembly actuates the bottom plate between opened and closed positions. The bottom plate maintains alignment to the top plate and adapter ring and resists cocking and distortion. The bottom plate seals to a connection portion of the adapter ring in any orientation of the heavy duty vent cap system, ranging from vertical to horizontal.

The vent cap system, according to claim 1, wherein said bucket interface means comprises a receptacle fixedly attached to said top plate and receptacle hole, said bucket interface means extending through said top plate. 3. The vent cap system, according to claim 1, further comprising installation bolts extending from a top side of said top plate, said installation bolts have connectors on top ends above said top side. 4. The vent cap system, according to claim 1, wherein said means for engaging said bucket interface means comprises a bearing stem with a tapered shoulder surface, said bearing stem extending through said bucket interface means through a receptacle hole. 5. The vent cap system, according to claim 1, further comprising a top push cone means being a generally frustoconical plate affixed to a bottom side of said top plate. 6. The vent cap system, according to claim 5, wherein said means for engaging said bucket interface means comprises a bearing stem with a tapered shoulder surface, and wherein said top push cone means engages said tapered shoulder surface. 7. The vent cap system, according to claim 1, wherein said retainer assembly further comprises a bottom push cone means, said bottom push cone means being a generally frustoconical plate affixed to a top surface of said bottom plate. 8. The vent cap system, according to claim 7, wherein said nut retaining means comprises a housing fixed in position adjacent to said bottom push cone means, said bottom push cone means in fixed engagement to said bottom plate. 9. The vent cap system, according to claim 1, further comprising a test port between said stem sleeve and said bottom plate so as to determine sealing engagement of said stem sleeve and said bottom plate. 10. The vent cap system, according to claim 1, wherein said guide means comprises an upper guide plate with an upper guide hole, a lower guide plate with a lower guide hole, and a plurality of guide bolts, lower guide plate in fixed engagement to said top surface of said bottom plate, said plurality of guide bolts fixedly attaching said upper guide plate to said lower guide plate and to said top surface of said bottom plate. 11. The vent cap system, according to claim 10, wherein at least one perimeter stem assembly inserts through said upper guide hole and said lower guide hole of the guide plates, supporting alignment of said upper guide plate and said lower guide plate with said bottom plate, during raising and lowering of said bottom plate between said opened position and said closed position. 12. The vent cap system, according to claim 1, further comprising a tubular member mounted between the upper guide plate and the lower guide plate, covering said plurality of guide bolts. 13. The vent cap system, according to claim 1, further comprising a test port between said sealing means of said bottom plate and said connection portion of said adapter ring so as to determine sealing engagement of said bottom plate and said adapter ring. 14. The vent cap system, according to claim 1, wherein distance between an end of said stem sleeve and said stem nut determines range of movement of said bottom plate, and wherein said stem sleeve and position of said stem nut above said bottom plate determines overall height. 15. The vent cap system, according to claim 1, wherein at least one perimeter installation stem has a shaft clamp mounted between said top plate and said connection portion. 16. A method of forming a suction pile assembly with a vent cap system according to claim 1, said suction pile assembly being comprised of a generally cylindrical body with a pile surface with vent holes on a closed end and a skirt on an opened end, said method of forming comprising the steps of: covering a vent hole on a pile surface with the vent cap system by placement of said welded portion of said adapter ring on said suction pile in alignment with said vent hole;attaching said connection portion of said adapter ring to said welded portion by engaging at least one perimeter installation stem through said top plate and said connect portion to said welded portion; andactuating said center stem member in threaded engagement to said stem nut; andmoving said bottom plate between an opened position and a closed position of the vent cap system in alignment along said center stem assembly according status of installation of the cylindrical body. 17.
