A method and apparatus are described for containing oil and/or gas spewing from a defective blowout preventer (BOP) stack located on a floor of an ocean using BOPstopper assemblies. A BOPstopper containment assembly is submerged below a surface of the ocean and positioned on a portion of the ocean floor that circumvents the defective BOP stack. Then, a BOPstopper valve assembly is submerged below the ocean surface and positioned on top of the BOPstopper containment assembly to contain the oil and/or gas. Each of these BOPstopper assemblies may comprise a plurality of flooding valves used to submerge the BOPstopper assemblies. Furthermore, each of these BOPstopper assemblies may comprise a plurality of reinforcement material input valves for reinforcing the assemblies with reinforcement material (e.g., cement and/or mud). The flooding valves and the reinforcement material input valves may be remotely controlled from a vessel floating on the ocean surface. |
