The primary purpose of these recommended
practices is to provide a basic reference to
promote the safe and reliable design, engineering, construction,
operation and maintenance of LNG fueling
systems. This document may be useful to those considering
using LNG for vehicle fueling and who want to learn
about how these facilities work, and to those seeking
information about the design and performance factors

that should be considered before investing in such a facility.
Code enforcement personnel who are charged with
permitting and inspecting LNG fueling facilities also may
find this document a useful reference.
This document provides basic background information
regarding LNG fueling systems. This document by itself
will NOT provide all of the information required to successfully
design, build, operate, service or inspect an
LNG fueling system. These recommended practices present
basic information that should allow the careful reader
to understand:
• the terminology used to describe LNG fueling systems;
• the various types of LNG fueling systems;
• the concepts involved in planning and designing LNG
fueling systems;
• the basic construction of an LNG fueling system;
• the basic steps required to properly operate and maintain
an LNG fueling system;
• references for further information.
