Description / Abstract:
This Code applies to onshore pipeline systems constructed with
ferrous materials and that transport gas. The principles and
processes embodied in integrity management are applicable to all
pipeline systems.
This Code is specifically designed to provide the operator (as
defined in section 13) with the information necessary to develop
and implement an effective integrity management program utilizing
proven industry practices and processes. The processes and
approaches within this Code are applicable to the entire pipeline
system.
Purpose and Objectives
Managing the integrity of a gas pipeline system is the primary
goal of every pipeline system operator. Operators want to continue
providing safe and reliable delivery of natural gas to their
customers without adverse effects on employees, the public,
customers, or the environment. Incident-free operation has been and
continues to be the gas pipeline industry's goal. The use of this
Code as a supplement to the ASME B31.8 Code will allow pipeline
operators to move closer to that goal.
Acomprehensive, systematic, and integrated integrity management
program provides the means to improve the safety of pipeline
systems. Such an integrity management program provides the
information for an operator to effectively allocate resources for
appropriate prevention, detection, and mitigation activities that
will result in improved safety and a reduction in the number of
incidents.
This Code describes a process that an operator of a pipeline
system can use to assess and mitigate risks in order to reduce both
the likelihood and consequences of incidents. It covers both a
prescriptive- and a performance-based integrity management
program.
The prescriptive process, when followed explicitly, will provide
all the inspection, prevention, detection, and mitigation
activities necessary to produce a satisfactory integrity management
program. This does not preclude conformance with the requirements
of ASME B31.8. The performance-based integrity management program
alternative utilizes more data and more extensive risk analyses,
which enables the operator to achieve a greater degree of
flexibility in order to meet or exceed the requirements of this
Code specifically in 1 the areas of inspection intervals, tools
used, and mitigation techniques employed. An operator cannot
proceed with the performance-based integrity program until adequate
inspections are performed that provide the information on the
pipeline condition required by the prescriptive-based program. The
level of assurance of a performance-based program or an alternative
international standard must meet or exceed that of a prescriptive
program.
The requirements for prescriptive- and performancebased
integrity management programs are provided in each of the sections
in this Code. In addition, Nonmandatory Appendix A provides
specific activities, by threat categories, that an operator shall
follow in order to produce a satisfactory prescriptive integrity
management program.
This Code is intended for use by individuals and teams charged
with planning, implementing, and improving a pipeline integrity
management program. Typically, a team will include managers,
engineers, operating personnel, technicians, and/or specialists
with specific expertise in prevention, detection, and mitigation
activities
