Abstract
BP's intent is to maintain well control from spud to abandonment. However, if for any reason well control is lost, we are designing our wells with the capability to stop or minimize the flow of oil into the water column using a capping system. The cap can stop the flow completely or we can minimize the flow where a collection system or plan could be required.
As part of BP's commitment to enhance deepwater safety and response preparation, BP has developed a comprehensive Global Deepwater Well Cap and Tooling Package. The system can be rapidly deployed to any of BP's operational regions in response to a well control event.
The system includes an Upper and a Lower capping stack, flow-back assembly, flex joint riser adapters, flex joint stiffeners, a comprehensive remote operated vehicle (ROV) tooling package, debris removal tools, dispersant distribution system, subsea hydraulic power unit with a launch and recovery system, subsea accumulator and 60-inch pipe shears for shearing a drilling riser. In total, the system contains over 250 components, 65 lifts, and weighs approximately 500 mT. The Global Deepwater Well Cap and Tooling Package is rated at 10,000 ft. water depth, 15,000psi and is fully air transportable onboard Antonov AN-124 and Boeing B747 200, 400 and 800 series heavy-lift aircraft. No disassembly is required to airfreight the system.
