Michael Hazzan takes us through a discussion of how to handle
mechanical integrity issues on equipment where the design basis and
"pedigree" of equipment can't be determined.
Developing a Mechanical Integrity
Program (1996) (link)
Andrew Remson provides a broad overview of necessary components for
preparing a mechanical integrity program: creating a covered equipment
list; designing an inspection, testing and preventive maintenance plan;
creating written procedures; offering process maintenance training; and
building in quality assurance components.
Angela E. Summers, Techniques for Assigning a Target Safety Integrity
Level (link)
(1998)
The new ANSI/ISA S84.01-1996 Application of safety instrumented systems
for the process industries, standard requires that companies assign a
target safety integrity level (SIL) for all safety instrumented systems
(SIS) applications. The assignment of the target SIL is a decision
requiring the extension of the process hazards analysis (PHA). The
assignment is based on the amount of risk reduction that is necessary to
mitigate the risk associated with the process to an acceptable level. All
of the SIS design, operation, and maintenance choices must then be
verified against the target SIL. This paper examines the six most common
techniques currently utilized throughout the process industries:
Consequence Only, Modified HAZOP, Risk Matrix, Risk Graph, Quantitative
Assessment, Corporate Mandated SIL.
