Saudi Aramco RBI Standards Guide

The document outlines the Risk-Based Inspection (RBI) standards for Saudi Aramco facilities, emphasizing the importance of Management of Change (MOC) procedures to control hazards during operational changes. It defines key concepts such as Mechanical Integrity, On-Stream Inspection, and Operational Cycle, which are critical for maintaining asset performance and safety. The document also mandates that all MOCs must be reviewed and signed by an RBI facilitator within the inspection unit.

Document Responsibility: Inspection Engineering Standards Committee SAEP-343

Issue Date: 7 July 2015


Next Planned Update: 21 August 2018 Risk-Based Inspection (RBI) for Saudi Aramco Facilities

IOW or Integrity IOW. Also referred to as Plant Integrity Window (PIW)#;


Changes in valid PIW's could be used for CMP in addition to RBI.

Management of Change: is a procedural system of control supported by


appropriate documentation to ensure that safeguards are in place to eliminate the
possibility of hazard introduction as a result of changes, other than replacement in
kind to equipment, fluid composition, operations, process parameters, control
parameters, trip and alarm set points as described in Loss Prevention Department
Saudi Aramco Safety Management Guide and API RP 750.

In RBI context it is a procedure supported by documentation to ensure that all


key parameters, identified and used as a basis for the RBI assessment, are
controlled to be within the assessment defined ranges. It also specifies that any
change to those parameters requires a review by the appropriate expertise for
impact on equipment deterioration or consequences.

The review of the MOC shall be performed by a Saudi Aramco employee.


All MOC’s shall be reviewed and signed by the RBI facilitator in the inspection
unit.

Mitigation: Limitation of any negative consequences of a particular event.

Mechanical Integrity: the ability of the assets to withstand the design loads for
optimum operation and maintenance of the assets at best condition throughout
its life cycle.

Off-plot Piping: Piping that is outside the boundary limits of the plant and is
generally, but not necessarily, designed to ASME B31.4/B31.8 code except in
area(s) set aside for piping within other code or government regulations.

On-Stream Inspection (OSI): The use of any number of nondestructive testing


procedures to establish the suitability of equipment for continued operation.
The equipment may, or may not, be in operation while the inspection is performed.

Operational Cycle: An operational cycle is defined as the initiation and


establishment of new conditions followed by a return to the conditions that
prevailed at the beginning of the cycle. Three types of operational cycles are
considered: the startup-shutdown cycle, defined as any cycle that has
atmospheric temperature and/or pressure as one of its extremes and normal
operating conditions as its other extreme; the initiation of, and recovery from,
any emergency or upset condition that must be considered in the design; and the
normal operating cycle, defined as any cycle between startup and shutdown that
is required for the vessel to perform its intended purpose.
