Definitions

  • the present invention relates to monitoring the operation of a subsea hydrocarbon production control system.
  • a shutdown philosophy is employed in the design of production control systems for subsea oil and gas wells, to ensure the protection of personnel, environment and equipment from the consequences that may occur as a result of abnormal operational conditions, accidental release of hydrocarbons or other accidents. This usually entails the inclusion of production shutdown and emergency shutdown mechanisms being built into the system, so that the system fails to a safe condition.
  • Examples of fail-safe shutdowns resulting from subsea failures, where relevant status information cannot be obtained using the existing system functionality, are those which occur between a well Christmas tree and the power distribution and protection module (PDPM) which is installed subsea and is the main subsea interface with Christmas trees providing electrical power, hydraulic power and communications to each Christmas tree.
  • PDPM power distribution and protection module
  • US-A-3 416 566 discloses a fail-safe vale operator mechanism
  • US 2009/212969 teaches the completion of a hard-wired communication system with a wireless communication system.
  • An embodiment of the invention to be described below entails including a separate, independent, dedicated, health monitoring module on a Christmas tree, for monitoring the status of all actuators and valves installed on the Christmas tree and wellhead.
  • the system has its own dedicated subsea wireless communication link capable of communicating information to a wireless receiving system on the PDPM and on other Christmas trees. Thus, in the event of failure of the normal communication links, the wireless channel is available.
  • the module is provided with its own battery back-up to provide power in the event of power supply failure.
  • the module sits alongside the normal process and control equipment in the Christmas tree mounted subsea control module (SCM) and can also be used to enhance the fail-safe decision making process in the SCM, by providing additional confirmation of the state of actuators and valves. If a shutdown should occur, but an indication that a device has gone to a fail-safe condition is not received, then this is an indication of a problem.
  • SCM subsea control module
  • the module can also form part of the normal decision making process by adding some intelligence to process the critical data which is related to a fail-safe condition.
  • Fig. 1 illustrates an implementation of the invention.
  • a master control station (MCS) 1 installed topside, provides the operator interface with subsea equipment and displays the current state of the various equipments and sensor information, enabling the operator to control the system.
  • the MCS 1 collates data such as the operational state of all subsea valves and data relating to the state of production fluids across an entire oilfield.
  • the MCS 1 interfaces with the subsea installed power distribution and protection module (PDPM) 2 which feeds electric power on lines 3, hydraulic power on lines 4, and communication on a line 5 to a plurality of Christmas trees 6, only two (A and B) being shown.
  • PDPM power distribution and protection module
  • Each Christmas tree 6 includes a subsea control module (SCM) 7 which controls all the Christmas tree processes by providing hydraulic power to actuate valves mounted on the Christmas tree and at the wellhead. It also receives process instrumentation signals from sensors mounted on the Christmas tree and at the wellhead. These are received and processed in a subsea electronics module (SEM) 8 housed within the SCM 7 and communicated via the system communication link to the PDPM 2, and then topside. Failure of the communications link between a Christmas tree 6 and the PDPM 2 will result in no valve and other status data being available from that tree.
  • SCM subsea control module
  • SEM subsea electronics module
  • a dedicated fail-safe monitoring module 9 is at each tree 6, which module provides data on the health of the valves, as well as their actuating mechanisms.
  • the module 9 includes its own interfacing, signal conditioning and processing and have its own dedicated sensors.
  • a back-up battery 10 is built-in so that the module can still operate in the event of electrical power failure. Health monitoring of the module 9 would form part of the normal equipment condition monitoring checks and the battery would be kept charged from the normal power supplies.
  • the production control system is provided with its own subsea wireless communication arrangement to communicate with the PDPM 2, so that in the event of a normal communication channel failure (copper wire, communications-on-power or fibre-optic) it has an alternative independent communication link. More particularly, at each tree 6, there is an RF antenna 11 for sending data to an RF antenna 12 at the PDPM 2 and thence to a fail-safe monitoring unit 13 in the PDPM 2. Thus, each Christmas tree 6 in the overall production well complex has its own SCM 7 and failsafe monitoring module 9 with a subsea wireless link 14. This enables individual Christmas trees to communicate with the PDPM and each other, providing alternative routes for valve and other status information to reach topside.
  • Fig. 2 illustrates an example of a configuration in which the fail-safe monitoring module 9 with its fail-safe monitoring (FSM) dedicated sensor package 15 is used in conjunction with the SEM 8 and its sensor package 16.
  • FSM fail-safe monitoring
  • a check can be made against the output from the fail-safe monitoring module 9 to see if this has also triggered a fail-safe mechanism as a result of the data from its dedicated sensor package.
  • a fail-safe mechanism gets executed if either or both the SEM and the fail-safe monitoring system takes the decision to trigger a fail-safe mechanism. This also adds redundancy to the system.
  • the invention can utilise a wireless communication system between topside and subsurface equipment that forms part of the latest hydrocarbon production control system.
  • a rapid response to dangerous situations can save lives, significantly reduce environmental pollution and thereby reduce the cost of rectifying situations which arise.
