RBI will not compensate for these 6 things:
1. Inaccurate or missing information
2. Inadequate designs or faulty equipment installation
3. Operation outside the acceptable IOW's
4. Not effectively executing the plans
5. Lack of qualified personnel or teamwork
6. Lack of sound engineering or operational
judgment
RBI is specifically targeted for what industry?
Hydrocarbon and chemical process.
Mechanical Integrity Focused
The RBI process is focused on maintaining the MI of
pressure equip. items & minimizing the risk of loss of
containment due to deterioration. RBI is not a
substitute for a PHA or hazard and operability
assessment (HAZOP). RBI compliments the PHA by
focusing on the MI related damage mechanisms & risk
management through inspection.
What types of equipment is covered by RBI?
1. Pressure vessels
2. Process piping
3. Storage tanks
4. Rotating equipment (pressure side)
5. Boilers and heaters
6. Heat exchangers (shells, floating heads, channels &
bundles)
7. Pressure-relief devices
What equipment is not covered by RBI?
1. Instrument and control systems
2. Electrical systems
3. Structural systems
4. Machinery components (except pump and
compressor casings)
Who is the Target Audience for API 580?
Inspection and engineering personnel who are
responsible for the equipment covered by 580.
Absolute Risk
An ideal and accurate description and quantification of
risk.
Consequence
An outcome from an event. There may be one or more
consequences from an event. Consequences may
, range from positive to negative. However,
consequences are always negative for safety aspects.
Consequences may be expressed qualitatively or
quantitatively.
Damage Mode
Ways that the damage mechanism may manifest itself.
For example, the damage mechanism "corrosion under
insulation" may precipitate a damage mode of either
generalized corrosion or localized corrosion.
Generalized corrosion could result in a large burst while
localized corrosion might be more likely to result in a
pinhole type
Risk-Based Inspection
A risk assessment and management process that is
focused on loss of containment of pressurized
equipment in processing facilities, due to material
determination. These risks are managed primarily
through equipment inspection.
Risk Estimation
Process used to assign values to the probability and
consequence of a risk. Risk estimation may consider
cost, benefits, stakeholders concerns and other
variables, as appropriate for risk evaluation.
Event
Occurrence of a particular set of circumstances. The
event may be certain or uncertain. The event can be
singular or multiple. The probability of an event
occurring within a given period of time can be
estimated.
External Event
4.1.16
External Event
Events resulting from forces of nature, acts of god,
sabotage, or events such as neighboring fires or
explosions, terrorism, neighboring hazardous material
releases, electrical power failures, forces of nature, and
intrusions of external transportation vehicles, such as
aircraft, ships, trains, trucks, or automobiles.
HAZOP (Hazard And Operability Study
A HAZOP study is a form of failure modes & effects
analysis (FMEA). HAZOP studies, which were
originally developed for the process industry, use
systematic techniques to identify hazards &
operability issues throughout an entire facility
