First Claim
Patent Images
1. A method comprising:
- providing a frame attached to an object;
providing a compliant structure having a predetermined compression versus force characteristic, a first end of the compliant structure abutting the frame;
providing a pressure plate disposed at a second distal end of the compliant structure;
whereinat a first predetermined pressure the compliant structure is fully extended allowing flow of a fluid past the compliant structure; and
at a second predetermined pressure the compliant structure is fully compressed preventing flow of a fluid past the compliant structure.

Abstract
Existing BOP devices are complex electromechanical systems exploiting hydraulic activation of pipe rams and/or shear rams. With tens of thousands of oil wells in the 1,500 oil fields that account for 97% of global production of the over 40,000 oil fields identified to date and failure rates as high as 50% in disaster situations it is evident that a simpler, increased reliability approach would be beneficial to the oil and gas industries. It would be further beneficial if the BOP was automatic requiring no monitoring locally to the BOP or remotely from the rig or production facility.
