The document outlines the Risk-Based Inspection (RBI) standards for Saudi Aramco facilities, emphasizing the importance of Hazard and Operability (HAZOP) assessments for identifying potential hazards and operability issues. It defines key terms such as Inspection Engineer, Inspection Effectiveness, and Inspection Plan, and highlights the need for systematic reviews and risk analysis in inspection processes. The document also discusses the Integrity Operating Window, which sets limits for process variables to maintain equipment integrity.

Hazard and Operability (HAZOP) Assessment as per OSHA 29 CFR 1910.119


and SAER-5437: A HAZOP assessment is a Process Hazard Analysis (PHA)
form of failure mode and failure effect analysis. HAZOP studies, which were
originally developed for the process industry, use systematic techniques to
identify hazards and operability issues throughout an entire facility. They are
particularly useful in identifying latent hazards designed into facilities due to lack
of information, or introduced into existing facilities due to changes in process
conditions or operating procedures. The basic objectives of the techniques are:
 To systematically review every part of the facility or process to discover
how deviations from the intention of the design can occur; and
 To decide whether these deviations can lead to hazards or operability issues.

Initial RBI Assessment: The first comprehensive RBI assessment performed on


any asset or group of assets (Plant or Unit).

In-plant piping: Piping that is inside the boundary limits of the plant and is
generally, but not necessarily, designed to ASME B31.3 code except in area(s)
set aside for piping within other code or government regulations.

Inspection Engineer: For the purpose of this document an Inspection Engineer


can refer to Inspector, Sr. Inspector or Field Supervisor that works in the Plant
Inspection Unit.

Inspection Effectiveness: Is qualitatively evaluated by assigning the inspection


methods to one of five descriptive categories ranging from Highly Effective to
Ineffective.

Inspection Plan: based on risk analysis refers to the output of the planning
process of determining what to inspect (which equipment), how to inspect
(technique), the extent of inspection (coverage) and when to inspect the
equipment. The inspection plan should detail the unmitigated risk related to the
current operation. For risks considered unacceptable, the plan should contain
the mitigation actions that are recommended to reduce the unmitigated risk to
acceptable levels. It is recognized that some risks cannot be adequately
managed by inspection alone and other mitigation actions make be required in
such circumstances.

Inventory Group: Inventory of attached equipment that can realistically


contribute fluid mass to a leaking equipment item.

Integrity Operating Window: Established limits for process variables that can
affect the integrity of the equipment and plant if the process/operating variables
deviate from the established limits beyond a predetermined amount of time.
Integrity Operating Window may be categorized as Safety IOW, Operational
