Pipeline system safety metrics
This Standard applies to oil and gas industry pipeline systems that convey
liquid hydrocarbons, including crude oil, multiphase fluids, condensate, liquid petroleum products;
natural gas liquids and liquefied petroleum gas;
liquid or dense phase carbon dioxide; or
gas, including but not limited to natural gas, fuel gas, compressed air, carbon dioxide, and nitrogen.
See Figures 1 and 2.
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.
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 PSSE.
This Standard covers
piping and equipment in onshore liquids pipelines, tank farms, pump stations, pressure-regulating stations, and measuring stations;
oil pump stations, pipeline tank farms, and pipeline terminals;
pipe-type storage vessels;
carbon dioxide pipelines;
piping and equipment in onshore gas pipelines, compressor stations, measuring stations, and pressure-regulating stations;
gas storage lines and pipe-type and bottle-type gas storage vessels; and
loading and unloading facilities for tankers or barge, truck, and rail when connected to the process.
See Figures 1 and 2.
This Standard does not apply to the following facilities and asset classes:
gas distribution systems as defined by CAN/CSA-Z662, Clause 12;
gas piping beyond the outlet of the customer’s meter set assembly (e.g., piping covered by CSA B149.1);
in-plant piping for drinking, make-up, boiler feed, or fire suppression water;
vent piping for waste gases of any kind operating at or near atmospheric pressure;
refueling facilities and refueling activities not directly connected to the pipeline system;
hydrocarbon storage in underground formations and associated equipment;
piping in natural gas liquids extraction plants, gas processing plants, gas manufacturing plants, industrial plants, and mines;
oil and gas production facilities; and
