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).

Availability

Note that the definition of availability given in IEC 60050-191:1990, 3.1.1, can be misleading because it can lead one to think that “availability” and “reliability” are the same concepts. This is not true because the meaning of “over a given time interval” is not at all the same for the concepts of “availability” and “reliability”. Even if the definitions of “availability” and “reliability” seem very close, these concepts are completely different, specifically: availability: item working at a given instant (no matter what has happened before); reliability: item working continuously over a whole period of time. “Availability” characterizes a function that can be interrupted without any problem and “reliability,” a function that cannot be interrupted over a whole period of time.

ROV

Free-swimming or tethered submersible craft used to perform tasks such as inspection, valve operations, hydraulic functions, and other general tasks.
  • NOTE: ROVs can also carry tooling packages for undertaking specific tasks such as pull-in and connection of rigid spools, flexible flowlines, umbilicals, and component replacement. Alternatively modules or tools may be deployed by crane and mated with the ROV subsea.
ROVs are grouped within the following main categories: — OBSROV (observation class ROV; MCA Class I and Class II)—These vehicles are small vehicles fitted with cameras/lights and may carry sensors or inspection equipment. They may also have a basic manipulative capability. They are mainly used for inspection and monitoring. — WROV (work class ROV; IMCA Class III)—These vehicles are large ROVs normally equipped with a five-function grabber and a seven-function manipulators. These commonly have multiplexing controls capability that allows additional sensors and tools to be operated without the need for a dedicated umbilical system. WROV are split into two classes: medium WROV and large WROV depending on their defined work scope. WROVs can carry tooling packages to undertake specific tasks such as tie-in and connection function for flowlines, umbilicals, and rigid pipeline spools, and component replacement.

HAZOP

HAZOP is a rigorous and widely accepted technique for hazard identification. A system or process is studied by a team who systematically look for the cause and effect of deviations from the norm. The team will, in general, be considering the following questions: • What is the design intention of the plant? • What deviations from the design could occur? • What might cause such deviations from the design intention? • What would be the consequences of such deviations from the design intention (such as fire, toxic release, etc.)? See appendix 6 for further information on HAZOP studies.

Barrier

A functional grouping of safeguards and controls selected to prevent the realization of a hazard. Each barrier typically includes a mix of: plant (equipment), process (documented and ‘custom and practice’) and people (personal skills and their application). The selected combination of these ensures the barrier is suitable, sufficient and available to deliver its expected risk reduction.
