BLOWOUT PREVENTER CONTROL SYSTEM AND METHODS FOR CONTROLLING A BLOWOUT PREVENTER

摘要

the present invention relates to a blowout preventer system (200) comprising a lower blowout preventer (BOP) stack (204) comprising a number of hydraulic components and a lower marine riser package (LMRP; 206) comprising a first control pod (310) and a second control pod (320) adapted to provide during use redundant control of hydraulic components of the lower blowout preventer stack where the first and the second control pods are adapted to being connected during use to a surface control system (330) and to be controlled during use by the surface control system wherein the blowout preventer system further comprises at least one additional control pod (340) connected to at least one additional surface control system (350) and to be controlled during use by the additional surface control system. In this way an improved blowout preventer system is provided.
