Failure Modes and Effects Analysis (FMEA)

FMEA is a methodology developed during the 1940s by the U.S. armed forces. It was later used in aerospace. It was applied to hazard analysis and critical control point during the race to the Moon. It was introduced to the automotive industry in the 1970s. The oil and gas sector started using FMEA in the late 1990s. The FMEA methodology is currently an accepted practice used by the many oil and gas companies and suppliers as part of their toolkit in various areas of operations and design. The FMEA is designed to identify failure modes and hazards affecting a focus item (focus items can be a component, a subsystem, or a system). The main goal is to come up with solutions to prevent the failure from happening, hence, improving the reliability of the focus item. It is preferably applied at as many levels as feasible of the system in question to include more specific solutions. The narrower the focus of the FMEA, the more specific the solution to the problem. FMEA has been used extensively in other industries, and it is becoming an integral part of the development process in the upstream oil and gas industry. The FMEA table follows the validation process discussed in the main document and presented in Figure C.1.

Dynamic Positioning Systems

Dynamic positioning systems are commonly used for stationkeeping on DW drilling rigs. These systems use information on the rig’s current location (e.g. as determined by a global positioning system and acoustic sensors) to control thrusters, which act to restore the rig to a position over the well’s center. Dynamically positioned drillships and semisubmersibles optimize stationkeeping by keeping the bow pointed in the direction of the metocean conditions.

Risk

The potential for damage to or loss of an asset. Risk, in the context of security, is the potential for a negative outcome to be realized from an intentional act. For chemical and petroleum facilities, examples of the catastrophic outcomes that are typically of interest include an intentional release of hazardous materials to the atmosphere, the theft of hazardous materials that could later be used as improvised weapons, the contamination of hazardous materials that may later harm the public, or the economic costs of the damage or disruption of a process. For the API SRA methodology, risk can be expressed as:
  • existing risk-the estimate of risk with existing countermeasures (R1)-and
  • proposed risk-the estimate of risk with the addition of proposed countermeasures (R2).
