Scope 1.1 This standard applies to: a) design; b) location; c) construction; d) exploitation; and (e) maintenance of facilities used for the liquefaction of natural gas, storage, vaporization, transfer, handling and transport by tanker of LNG. It also contains requirements for staff training. 1.2 With respect to facilities used to load LNG into ships or to unload ships, this standard contains requirements for the piping that connects the loading/unloading arms and the storage tank as well as the piping and accessories on the pier. 1.3 This standard applies to all tanks used for the storage of LNG, including vacuum-insulated tanks. 1.4 This standard does not apply to tanks in frozen ground. 1.5 This standard includes non-mandatory guidelines for small LNG installations (see the definition of “small installation” in Chapter 3 and Annex B). 1.6 This standard does not cover: a) the transport of refrigerant liquids; b) transport of LNG by train or ship; c) transportation of regasified LNG by pipeline outside the boundaries of the installation; and (d) installations designed to enable the use of LNG as a fuel for road vehicles, locomotives and ships. 1.7 Unless otherwise stated, all pressure values in this document are gauge pressures. 1.8 All pipe diameters are nominal diameters (NPS). 1.9 In this standard, values are expressed in SI (metric) units. Values in parentheses are for information only. 1.10 In CSA standards, the term “shall” indicates a requirement, that is, a requirement that the user must follow to ensure compliance with the standard; “should” indicates a recommendation or what is advisable but not obligatory to do; and “can”, a possibility or advice.
