Abstract
A blowout preventer system includes a blowout preventer stack having hydraulic components. The blowout preventer stack is coupled to a lower marine riser package that includes additional hydraulic components. The lower marine riser package includes control pods that enable redundant control of the hydraulic components of the blowout preventer stack and the additional hydraulic components of the lower marine riser package. These control pods include frames, valves, and stack stingers that facilitate connection of the control pods to hydraulic components of the blowout preventer stack, but do not include riser stingers that facilitate communication of control fluid to the additional hydraulic components of the lower marine riser package. The stack stingers extend through central apertures of bottom plates of the control pod frames and facilitate communication of control fluid from the valves to the hydraulic components of the blowout preventer stack. Additional systems, devices, and methods are also disclosed.
