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.

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).
The delivery points, "complex" interconnections, storage facilities, terminals and compressor stations are not
included in this scope.

SIST-TS CEN/TS 15174:2008
CEN/TS 15174:2006 (E)
One of the primary tasks of maintenance and operating organization (pipeline operator) is to match resources
to the workload. The objective of such matching is to achieve the agreed pipeline performance at optimum
resource costs. This objective can be achieved in many ways and depends on the policy of the pipeline
operator. As regards the organization of operation and maintenance (pipeline related activities) of a pipeline
system, the minimum requirements are:
organization chart:
The pipeline operator shall keep an up-to-date chart of its management and maintenance organization.
responsible persons:
The pipeline operator shall identify the responsible persons and their deputy or deputies for specific fields
of activity including, if applicable, authorization of permits to work.
personnel and training:
The relevant personnel shall be familiarized with and have access to the operating instructions. The
pipeline operator shall provide adequate training for it to ensure the safe pipeline related activities of the
pipeline.
3.2.1.6 Training, awareness and competence
Training, awareness and competence (EN ISO 14001:2004, 4.4.2)
The organization (pipeline operator) shall identify training needs. It shall require that all personnel, whose work
may create a significant impact upon the environment, have received appropriate training.
It shall establish and maintain procedures to make its employees or members at each relevant function and
level aware of:
the importance of conformance with the environmental (and safety) policy and procedures and with the
requirements of the environmental (and safety) management system;
the significant environmental (and safety) impacts, actual or potential, of their work activities and the
benefits of improved personal performance;
their roles and responsibilities in achieving conformance with the environmental (and safety) policy and
procedures and with the requirements of the management system, including emergency preparedness
and response requirements;
the potential consequences of departure from specified operating procedures.
Personnel performing the tasks which can cause significant environmental (and safety) impacts shall be
competent on the basis of appropriate education, training and/or experience.
Training – General (CEN/TS 15173:2006, 9.1.1)
All personnel – (employees of the natural gas transport (pipeline) operator, but also of the subcontractors) are
selected, trained and developed to carry out their respective technical duties in a safe and efficient manner.
In addition, the pipeline operator may define and set up procedures to ensure that its employees working at
each level are aware of:
11
---------------------- Page: 13 ----------------------
SIST-TS CEN/TS 15174:2008
CEN/TS 15174:2006 (E)
the importance of conformance to the company policy, and to the requirements of the management
system;
their roles and responsibilities in achieving conformance to the company policy, the procedures and the
requirements of the management system.
For persons employed in the gas sector, completed training qualifying them either as gas fitters, electricians,
measurement and control engineers or a metal-processing trade education may be considered sufficient.
Training on the job (internal training) (CEN/TS 15173:2006, 9.1.2)
When beginning their employment, new employees receive detailed instructions related to the special
circumstances that prevail when working with the substance gas. More specifically, the employees are
informed about what to refrain from doing on grounds of safety, especially in the areas of surface facilities (e.g.
taking along mobile telephones, flammable material, intervention in the system without prior consultation with
the technical officer in charge, etc.).
Only when it can safely be assumed that an employee is familiar both with the local conditions and the
functional tasks of the system, and is able to take all the necessary safety provisions in practice correctly, can
he/she be assigned an unsupervised task.
Training courses (CEN/TS 15173:2006, 9.1.3)
The employees' basic training should comprise the following courses, according to their position and work:
Safety engineering in gas utilities
The aim of this course is to convey basic knowledge with regard to personal protective equipment, noise,
electrical facilities, and operating materials, machine facilities, handling of cranes and elevators, rules
related to pressure tanks and explosion protection. Depending on the assigned area, it may also be
necessary for employees to become familiar with methods of handling gas pressure regulation stations,
gas odorisation, gas compressors, plants, measuring stations and cathodic protection plants.
First Aid:
This course aims at teaching employees the First Aid procedure in case of accidents.
Fire fighting training
The aim of this course is to teach employees what steps can be taken to prevent fire and the procedure
to be followed when extinguishing fires - tailored to meet the individual workplace requirements. It can
include a practical fire fighting exercise in this course.
Hazardous material
This course aims at teaching employees methods of handling hazardous materials encountered at work,
especially as regards their storage and transport. Moreover, the course intends to teach employees about
labelling and the obligation to provide information with regard to such materials.
In order to benefit from one's own mistakes and those committed by others, superiors should schedule
meetings with employees several times a year with the aim of avoiding such mistakes in future. More
specifically, all situations that produce accidents causing personal harm must be carefully analysed and the
conclusions drawn there from disseminated to the involved people.
It is also recommended to document all courses and training including the persons who attended.
