A blowout preventer system including a lower blowout preventer stack comprising a number of hydraulic components, and a lower marine riser package comprising a first control pod and a second control pod 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 and to be controlled, during use, by the surface control system. The blowout preventer system further including at least one additional control pod connected to at least one additional surface control system and to be controlled, during use, by the additional surface control system.

High pressure blowout preventer system

Provided is a life cycle tracking system including a memory and a processor. The memory includes instructions that, when executed by the processor, cause the processor to perform certain operations. For example, the operations can include effecting a change in a first database including data related to a set of components installed on a blowout preventer stack, in response to a drag and drop operation having been performed on a human machine interface. The change can include associating information from a second database to the first database. The second database includes data related to a set of spare components.

Graphical indexing for life cycle management of drilling system assets

A control system for a subsea blowout preventer (BOP) positioned in a lower stack, the lower stack releasably engaged with a lower marine riser package (LMRP). The control system includes a surface logic solver positioned at or adjacent the surface of the sea that generates commands for operating the subsea BOP, a first subsea logic solver attached to the LMRP and in communication with the surface logic solver so that the first subsea logic solver receives the commands from the surface logic solver, and a second subsea logic solver attached to a hydraulic control unit in the lower stack. The second subsea logic solver is in hydraulic communication with the subsea BOP, and the first subsea logic solver so that the second subsea logic solver receives the commands from the first subsea logic solver and implements the commands by activating the hydraulic control unit to operate the BOP.

Sil rated system for blowout preventer control

A BOP system for use in a high pressure subsea environment, including a BOP stack including a lower marine riser package and a lower stack portion, the lower stack portion having a plurality of BOP rams attached to a subsea wellhead. The system also includes a riser subsystem extending from a drilling vessel to the BOP stack and providing fluid communication therebetween, a ship board subsystem electronically, mechanically, and hydraulically connected to the BOP stack and the riser subsystem to control the functions of the BOP stack and the riser subsystem, and a safety instrumented system having a surface logic solver and at least one subsea logic solver, the safety instrumented system in communication with at least a portion of the BOP rams to act as a redundant control system in case of failure of the ship board subsystem.
