CAN/CSA-Z341 Series-02

Z341.1-02 Reservoir Storage 1 Scope 1.1 This Standard sets out the minimum requirements for the design, construction, operation, maintenance, abandonment, and safety of hydrocarbon storage in underground formations and associated equipment. The equipment considered includes a) storage wellhead and Christmas tree assemblies; b) wells and subsurface equipment; and c) safety equipment, including monitoring, control, and emergency shutdown systems. Hydrocarbons within the scope of this Standard include crude oil, diesel, natural gas, methane, ethane, propane, butane, and other hydrocarbons by themselves or in mixtures. 1.2 The scope of this Standard is shown in Figure 1. 1.3 This Standard does not apply to a) underground storage facilities for gases or fluids other than hydrocarbons, such as storage facilities used for air storage, unless these fluids are used specifically for the displacement of stored hydrocarbons; b) underground storage facilities used for storing substances other than hydrocarbons, such as reaction chambers and waste disposal; c) underground storage in overburden materials involving the use of tanks, such as gasoline tanks; d) design and fabrication of pressure vessels that are covered by pressure vessel codes; e) heat exchangers, pumps, compressors, and piping in processing plant facilities, manufacturing plants, or industrial plants that are covered by appropriate codes; f) gathering lines, flow lines, metering, compressors, and associated surface equipment beyond the first emergency shutdown or block valve; or g) storage of hydrocarbons containing hydrogen sulphide in concentrations greater than 10 mol/kmol. 1.4 It is not the intent of this Standard to prevent the development of new equipment or practices, nor to prescribe how such innovations should be handled. 1.5 Where any requirements of this Standard are at variance with the requirements of other Standards or Codes incorporated by reference into this Standard, the requirements of this Standard take precedence. 1.6 The requirements of this Standard do not apply retroactively to existing installations and installations under construction at the time of its approval, but they do apply to the extension, replacement, maintenance, and upgrading of such installations. 1.7 In CSA Standards, ?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. Legends to equations and figures are considered requirements.
