The ram close hydraulic circuit is shown in red on the above caption. The ram closing pressure also serves to open the bonnets for ram change. When the bonnet bolts are unscrewed and closing pressure is applied, pressure pushes the ram inward and at the same time moves the bonnet away from the preventer body
The ram open hydraulic circuit is shown in green on the above caption. Ram opening pressure also serves to close the bonnets. Hydraulic control pressure draws the bonnets tightly against the preventer body; bolts serve only to hold bonnets closed.

The blow out prevention valve is a one time use only and seals the line closed. Once done and if it works at all on ocean based drill platforms means the well cannot be adequately sealed with slurry or repaired for further production. I'm the designer of the caphead that stopped the deep horizon/ macondo well leak. I'm currently employed on Alaska's North slope oilfields in Prudhoe Bay and am,a mechanic with 30 years experience in pipeline repair and maintenance. In June 2010 I watched the news coverage as the horizon crew used underwater robotics to cut bent sections away from wellhead piping. That left several feet of pipe sticking out of the seafloor, which also had a flange inches away at pipe end. I designed a spool that could be lowered onto the 7 inch well pipe and had ears or wings that could be used to lock and secure the caphead to the well pipe. Using chevron seals would use the wells own pressure to seal the caphead. Later that evening I was told there was a number I could reach the horizon crew. Finding the number online called and spoke with the "horizon helpline" personnel. Later I emailed my design by zipping and was later emailed back and told my design was unusable. Several weeks later I watched as my design caphead stopped the macondo wells leak. I neglected to file for a patent and was cheated out of recognition for my design and. A slap in the face for my contribution. I still have the copy of my design sub as well as emails. Seeing later that the ocean based oil production industry still uses the same type blowout. Prevention valves means the risk of using this type of shutdown system leaves the well incapable of repairs or properly abandoning. The risk of creating another massive spill is greater. The type valves I designed can be tested periodically to check operation and pressure isolated if the Bop valve needs repair or replacement. The difference in buying into upgrades means alot less than the 100 billion (and still rising.) And will mean if the Bop prevention valves malfunction during a test it can be repaired and well returned to production rather than wondering what to do next. My designs will not be for free and will be patented. Future plans are to start my own deep water repair company specializing on ocean based drill platf as well a marketing valves for a better bop.

Dear, Thank you for sharing your experience and insights regarding blowout prevention valves and your design contribution during the Deepwater Horizon incident. It's impressive to hear about your extensive experience in pipeline repair and maintenance. It's unfortunate to hear that your initial design was not utilized during the crisis and that you feel you were not properly recognized for your contribution. Intellectual property and patent rights are important considerations in such situations, and it's understandable that you would want to protect your designs moving forward. Your suggestion for periodic testing and the ability to repair or replace malfunctioning blowout prevention valves certainly seems valuable in terms of maintaining safety and operational efficiency in the oil production industry. If you decide to pursue patenting your designs and starting your own deep-water repair company, it could provide an opportunity to further develop and implement your innovative solutions. We wish you the best of luck with your future endeavors and hope that your contributions will be recognized and appreciated in the industry.

a marvelous video Dr khaled, and very good simulation
Thanks a lot !
You Welcome
thank u Dr.Khaled
