Pipeline system safety metrics
This is the second edition of CSA Z260, Pipeline system safety metrics . It supersedes the previous edition published in 2019. This Standard provides requirements to establish a set of common safety metrics for pipeline systems along with an approach that can be used across the pipeline industry and regulatory jurisdictions for categorizing unintentional pipeline system releases and developing leading indicators. Mandatory reporting requirements are defined by regulatory agencies, and this Standard does not supersede incident reporting requirements set by these agencies. This Standard is intended for use in the process and performance improvement of pipeline system safety and communicating pipeline system safety performance where organizations have discretion in setting metric definitions. The major revisions to this edition include the following
In developing this Standard, previous and existing standards were used to provide the basis and background as appropriate. These include, but are not limited to, legislation, best practices, policies, standards, and applicable codes. CSA Group and the Z260 Technical Committee acknowledge the contributions of the American Petroleum Institute (API) and its employees to provide input to this Standard and its industry-wide approach to pipeline system safety metrics. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of the Canadian Energy Pipeline Association (CEPA) and its member organizations. This Standard was prepared by the Technical Committee on Pipeline System Safety Metrics, under the jurisdiction of the Strategic Steering Committee on Petroleum and Natural Gas Industry Systems, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group
This Standard applies to liquid and gaseous energy systems that convey
Notes: 1) Non-hydrocarbon products used as process fluids and transported by operating companies by pipeline or within pipeline facilities are considered within the scope of this Standard, provided that those products are used in facilities connected to the pipeline system. 2) Fluids used within equipment supporting the pipeline system operation, including consumables such as lubricating or hydraulic fluids, are considered within the scope of this Standard, provided that the equipment is connected to the pipeline system at the time of the pipeline system safety event (PSSE)
This Standard applies to
Note: Refer to Annex D for more information
This Standard does not apply to the following facilities and asset classes
Notes: 1) For Items f) and h), users of this Standard should refer to IOGP Report 456 for metrics and guidance specifically focused on wells, production facilities, and storage in underground formations. 2) For Items g) and j), users of this Standard should refer to ANSI/API RP 754 for metrics and guidance specifically focused on refineries, processing plants, and LNG facilities
The following are not covered within this Standard as PSSEs or metrics
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
