Introduction
This Technical Specification describes the management of pipeline systems. It covers design, construction,
commissioning, operation, maintenance and abandonment, all in order to provide a pipeline system for the
safe and secure transmission of gas.
The text of this Technical Specification is based upon the existing documents EN ISO 14001 (Environmental
Management Systems), EN 1594 (Pipelines for maximum operating pressures over 16 bar – Functional
requirements) and CEN/TS 15173 (Frame of reference regarding Pipeline Integrity Management System).
Among the EN ISO standards, EN ISO 14001 appears to be the most appropriate reference for a Safety
Management System for natural gas transmission pipelines no reference is given to EN ISO 9000 series.
Not all the references specifically cover pipeline management. However they give a good overall guide as far
as the topic in question is concerned.
1 Scope
This Technical Specification is applicable to pipelines for the transmission of processed, non-toxic and non-
corrosive natural gas according to ISO 13686 in on land gas supply systems, where:
the pipeline elements are made of unalloyed or low-alloyed carbon steel;
the pipeline elements are joined by welds, flanges or mechanical couplings;
the pipeline is not located within commercial or industrial premises as an integral part of the industrial
process on these premises except for any pipelines and facilities supplying such premises.
This Technical Specification applies both to new and existing pipelines and covers pipelines which begin after
the gas producer's metering station and ends at the boundary of the delivery station on the premises of the
customer. Installations like Under Ground Storage, Compressor stations and LNG plants are excluded from
this scope.

3.1 Guidance for the user
This clause contains important notes for the user of this Technical Specification. Understanding provisions
below are necessary for the proper interpretation of this Technical Specification.
This Technical Specification is intended for use by individuals who possess a basic appreciation of quality
management, environmental management, pipeline operation, maintenance and integrity issues.
This Technical Specification proposes the topics as given in the matrix in 3.2 to be included in a Safety
Management System.
The structure is a general framework that is meant to cover general needs of pipeline operators with special
emphasis on safety aspects of pipeline management (e.g. public safety, pipeline condition monitoring, etc.).
Where there are preferences over either of the topics included or the structure itself, it is at the user’s
discretion to make the necessary adjustments according to specific needs.
The majority of the 18 topics contain more than one reference. The user may see this as duplication. The aim
of this Technical Specification was not to make a prioritised selection of the “best” references quoted under
each topic, but rather to leave at the user’s discretion to make his own choice.
The text of the references quoted in this Technical Specification is the original text. However to achieve the
required level of consistency between texts from different sources, expressions in brackets help the user in
the proper interpretation of certain phrases.
There may be other existing documents under a single topic not referred to in this Technical Specification that
give more specific guidance for the relevant topic, however the intention of this Technical Specification is to
include widely known, used and available documents.
There are objects and structures referred to under certain topics, which are outside the scope of this Technical
Specification (e.g. compressor stations). The Safety Management System proposed in this Technical
Specification covers only pipelines as defined in the scope. However it is at the user’s discretion to include
other objects and structures in its own management system.
Different approaches used in the wording of texts referred to in this Technical Specification may suggest to the
user that there are references more important than or have precedence over others (e.g. use of shall, should,
must etc). It is at the user’s discretion to interpret these differences properly and apply a uniform approach.
3.2 Matrix
3.2.1 Management system
3.2.1.1 Management system
General requirements (EN ISO 14001:2004, 4.1)
The organization (pipeline operator) shall establish and maintain an environmental management system, the
requirements of which are described in Clause 4 of EN ISO 14001:2004.
Safety and Environment - Principles (CEN/TS 15173:2006, 9.4.1)
(…) natural gas transport operator (pipeline operator) may implement a safety / environmental management
system, following an external frame of reference. Such reference systems have a very wide scope and go
beyond PIMS' requirements. However, the specific safety / environmental activities described below may be
implemented in the PIMS.
Quality systems (EN 1594:2000, Clause 4)
The life of a pipeline for transmission of gas can be divided into three phases:
the design;
the construction and testing;
the operation and maintenance.
A quality system should be applied to the design, construction, testing, operation and maintenance activities in
accordance with this Standard.
Reference may be made to the EN 9000 series of standards or to equivalent quality assurance systems.
After the pipeline has been commissioned, the integrity should be maintained by a precisely defined
programme of operation, maintenance and condition monitoring (a pipeline integrity management system).
Competent personnel capable of assessing the quality of the work within the scope of this standard shall be
employed for in all activities in the design, construction, testing and operating phases.
PIMS – General (CEN/TS 15173:2006, 4.1)
PIMS is defined as Pipeline Integrity Management System. It is a safety management system, whose field is
pipeline integrity. The field does not cover occupational health.
Each natural gas pipeline operator has a system to manage all its resources and activities. This management
system is specific to each operator. It generally integrates all the following activities: storage, compression,
transportation and delivery of natural gas.
PIMS is based on such principles as:
adoption of high technological standards in the construction;
carrying out of proactive measures for ensuring that the pipeline system is maintained fit for purpose;
working out of emergency procedures;
incidents investigation;
training of personnel,
definition of roles and responsibilities of personnel.
It follows the basic principle plan, do, check and act (PDCA) which includes policy, planning, implementation
and operation, inspection and corrective actions, and management review.
In this management system, the PIMS represents all the resources (organisation, equipment, know-how, etc.)
and activities provided by each natural gas pipeline operator to control the hazards associated with its natural
gas transport network. (see boundary of PIMS below)
The goal of the PIMS is to manage:
the safety of the employees and the public;
the protection of urban, natural or industrial environment;
the service life and reliability of industrial equipment (natural gas transport network)
taking technical and economic requirements into account.
NOTE Further in the document, these three items are summarised by the expression “safety and protection of the
environment”
Boundaries of the PIMS (CEN/TS 15173:2006, 4.2)
The structures in the scope of PIMS are on-shore pipelines and related equipment (insulating devices,
disconnecting devices, pre-pressure reduction devices, cathodic protection equipment and simple
interconnections).
