Liquefied natural gas refuelling stations installation code

active, Most Current
Organization: CSA
Publication Date: 1 January 2021
Status: active
Page Count: 92
ICS Code (Petroleum products and natural gas handling equipment): 75.200
scope:

Inclusions

This Code applies to

a) the design, location, construction, operation, operator training, and maintenance of LNG refuelling stations, including LNG mobile refuelling units (MRUL), with single containment storage tanks up to 265 m3 (70 000 gal) water capacity employed for vehicle LNG dispensing operations;

b) shop-fabricated and assembled refuelling stations when used to receive and store LNG to dispense LNG into vehicle fuel tanks; and

c) the LNG portion of stations that vaporize and pressurize LNG to obtain CNG, up to and including the odorizer's outlet isolation valve. When a refuelling station dispenses fuels in addition to LNG, this Code applies only to the LNG refuelling system and equipment.

Exclusions

This Code does not apply to:

a) indoor refuelling;

b) marine vessel LNG fuelling facilities;

c) rail locomotive LNG fuelling facilities;

d) equipment, piping, or tubing downstream of the L/CNG system odorizer's outlet isolation valve (see CSA B108.1);

e) CNG equipment including storage, compression, and/or dispensing equipment;

f) CNG mobile refuelling units (MRUG) or CNG portable refuelling units (PRUG);

g) equipment, piping, or tubing downstream of the gas pressure regulator for closed boil-off gas systems;

h) dispensing of LNG other than into vehicle or cargo fuel tanks;

i) liquefaction equipment;

j) LNG engine fuel systems;

k) LNG and CNG repair garages;

l) underground piping or tubing for LNG;

m) LNG storage tanks, pumps, and process piping or tubing when an LNG refuelling station is sharing the LNG plant storage tank; and

n) transfer of LNG from the LNG vehicle fuel storage system of one vehicle to the LNG vehicle fuel storage system of another vehicle. This does not apply to a bulk fuel storage system.

Pressure terminology

All references to pressure throughout this Code are to be considered gauge pressures, unless otherwise specified.

Terminology

In this Code, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; "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 Code.

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.

Use of SI units

The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for information and comparison only.
