4 PIMS
4.1 General
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 (see diagram below).
PIMS is based on such principles as:
- adoption of high technological standards in 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.
Figure 1 — Architecture of a natural gas operator
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 ».

4.2 Boundary of the PIMS
The structure in the scope of PIMS is 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.
4.3 Objective of the frame of reference
The frame of reference aims at describing the resources (mainly organisation and know how) and activities,
for which the gas transport operator is responsible, that help to ensure the safety and protection of
environment. Authorities are also responsible for other matters (such as land use planning and emergency
schemes) which are not described in the report.
The frame of reference presents, in the broadest possible manner, all the resources and activities provided for
above. These resources and activities are nevertheless implemented according to the technical and economic
requirements specific to each structure.
It should be noted that, for more precision about these resources and activities, it is possible to refer to the
following standards, which often meet the minimum requirements of this frame of reference and give more
details:
- EN 1594: Pipelines for maximum operating pressure over 16 bar - Functional requirements (applicable in
Europe),
- ISO 13623: Petroleum and natural gas industries - pipeline transportation systems (applicable outside
Europe),
- national pipeline standards.
The present document aims at serving:
as a frame of reference for natural gas pipeline operators,
It is based on the best practices of natural gas pipeline operators and takes into account remarks of
natural gas pipeline operators.
NOTE The IGU 1998 survey and "Pipeline Integrity Management and Safety" report conducted by the
st
WOC 4/SG 4.3 and presented to the 21 IGU World Gas Conference (Nice, France 2000) have identified best
practices. This work supports this frame of reference.
in the medium term as a frame of reference for authorities,
it supports the efforts made by the natural gas pipeline operators
as a guide for optimal natural gas pipeline management.
it gives means of support for management
it demonstrates the coherency of the security, environment and quality management systems.
This framework provides guidance on the safe management of pipelines.
It is based on the principles of the maintaining of the high safety level reached by Gas pipeline operators,
proved by the good historical data and of its improvement when possible and necessary.

6 System management process
6.1 General
This section provides a summary description of the activities specific to the management process that
contributes to the safety and protection of environment.
Operators can manage the safety/environment aspects of all the resources and activities they are involved in,
through the use of a safety/environment management system based on the requirements of a frame of
reference. The standards here after are examples of such a frame of reference: ISO 14000, BS 8800, OHSAS
18001, or DNV ISRS standards.
In this context, safety / environment policies and objects can be defined. Management then undertakes to
develop and implement a safety / environment management system and continuously maintain, or improve its
efficiency, if necessary.
6.2 Management commitment
The top management provides visible and active leadership in developing and maintaining a supportive
culture of Environmental and Safety matters.
The top management may define an Environmental and Safety Policy in which overall objectives and a
commitment to maintain or improve environmental and safety performance are clearly stated.

SIST-TS CEN/TS 15173:2008
CEN/TS 15173:2006 (E)
6.3 Organisation and responsibilities
The organisation and responsibilities for the management of Environmental and Safety may be defined and
documented.
The role, responsibility, accountability, authority and interrelation of the personnel who manage, perform or
verify work affecting environmental and safety matters are defined:
in the provision of resources, ensuring staff awareness of relevant hazards and the compliance with the
environmental and safety policy;
in the identification, recording and follow-up of corrective or improvement actions;
in the control of abnormal situations including emergencies;
in the identification of training needs, the provision of training and the evaluation of its effectiveness;
in the implementation of the system.
6.4 Hazard identification an control
Potential hazards for environment and safety from the transport activity may be identified and assessed.
Appropriate controls and systems are implemented to reduce and manage those hazards.
The organisation may define and set up procedures in order to identify the hazards, assess their relevance
and implement the necessary control measures, both in routine and non-routine activities.
The organisation includes the assessment results and the effects of the controls in the company policy when
relevant.
6.5 Planning and performance monitoring
Planning to achieve safety objectives is required with performance indicators to measure and monitor the
implementation of Environmental and Safety Policies on a regular basis.
The Operator sets up a Performance Measurement framework in order to demonstrate effective management
of pipeline safety and environmental performance according to:
the incidents that can happen;
the consequences severity;
the operational control (i.e. air emission, patrolling, intelligent pigging and so on);
the elements of the Management System (i.e. public awareness, visit to landowners, training courses and
so on).
6.6 Information management
Environmental and Safety information are controlled to ensure that they are accurate, relevant and readily
available to enable safe operations.
Procedures for ensuring that this information is communicated to and from employees and other interested
parties may be defined.
10
---------------------- Page: 12 ----------------------
SIST-TS CEN/TS 15173:2008
CEN/TS 15173:2006 (E)
6.7 Audit
Internal or external audits should be conducted to assess the effectiveness of the PIMS and identify areas to
improve environment and safety standards.
In particular the audit procedures should mainly:
determine if the Management System has been properly implemented and maintained and if it is effective
in meeting the organisation's policy and objectives;
review the results of previous audits,
provide information on the results of audits to management.
7 Equipment process
7.1 General
The equipment process is the first and basic step that enables the natural gas transport network operator to
ensure a safe and continuous supply of natural gas.
The equipment process, in the present document frame, means the design and the construction management
and it is integrated in the natural gas transport Pipeline Integrity Management System (PIMS) in accordance
with the principles set above in Clause 4 (cf. Schematic diagrams), both for new constructions and
modifications.
Both the design and the construction should be carried out in accordance with the principles and the
objectives described in the Environmental and Safety Policy.
This clause provides a summary description of the two activities considering in particular the safety and
protection of environment.
7.2 Design management
7.2.1 Design principles
The management and the control of the design of new plants and of modifications of the existing ones are
carried out assuring the fulfilment of the criteria and requirements about safety, in observance of the relevant
national law.
Besides, the decisions and the solutions adopted in the design are in accordance with the Environmental and
Safety Policy of the Company.
The design of the pipeline shall lead to a safe system for transmission of gas.
7.2.2 Standards
In the planning, design actions and choices refer to specifications on the basis of prescriptive codes and
procedures that are well documented and recognised both at national and at international level such as
European, international and national standards.
The natural gas transport operator can decide to define and adopt internal company standards based on the
above references, adapted to its own skills and know-how.
11
---------------------- Page: 13 ----------------------
SIST-TS CEN/TS 15173:2008
CEN/TS 15173:2006 (E)
The whole set of these standards satisfies the operating conditions in each State and ensures compliance
with its specific legal requirements. It covers the pipeline design matter, like sizing, location, correct selection
of materials and components, construction details, testing and commissioning into services.
Besides, they apply equally to associated plants and their components such as reduction stations, pressure
control stations, metering stations and so on.
7.2.3 Design supervision
The extent and detail of the design of a pipeline is sufficient to demonstrate that the integrity and availability
can be maintained during the design life of the pipeline.
In order to manage the design activity of pipelines and equipment for assuring a high safety level and to
provide solutions for preventing damages, development design plans can be arranged, according to the
importance of the new pipeline or the modification.
These plans are suited for identifying:
scope of the work,
organisation for the execution (people and responsibilities),
design data,
execution activity,
expected document list,
execution programme,
planning of surveillance activity and safety aspects auditing,
planning and control of the design.
The design takes into consideration all technical issues together with environmental and safety aspects.
Besides, the controlled release of gas or other materials during the following construction phase may be taken
into account.
7.2.4 Design overview
The operator defines, as a first step, the general design data such as the diameter, the design pressure, the
safety factors, the wall-thickness, the distance from buildings, the grade of the steel, the routing, the stations,
the line systems etc.
Some of the most important aspects for the safety and environmental protection are reported in the following:
Route selection:
The pipeline route is selected with regard to soil characteristics, other pipelines and nearby buildings,
sensitive areas, environment impacts and economical aspects.
In the areas crossed by the pipeline, the operator adopts the necessary safety measures that have been
taken according to legislation or applicable standards.
Wall thickness specifications:
12
---------------------- Page: 14 ----------------------
SIST-TS CEN/TS 15173:2008
CEN/TS 15173:2006 (E)
The required pipeline thickness and the related safety factor, depending on steel quality and on the
population distribution, are fixed in the legislation or standards.
Crossing of railways, waterways, roads, flood defences can be subjected to special conditions.
The additional stress with respect to that determined by the internal gas pressure can also be evaluated
for the relevant sections (i.e. non-stable soil, waterways, water formation, high traffic condition and so on).
Special pipe geometry and wall-thickness should be chosen to obtain a lower stress level.
Where external interference is a potential hazard, significant prevention measures such as increasing of
wall thickness depending on steel quality and safety factor or depth of cover or mechanical protection can
be considered.
Pressure control:
It can be assured, by means of suitable equipment, that the intended maximum operating pressure
cannot be exceeded.
Besides, the line can be sectioned by means of shut-off devices located at a distance depending on pipe
diameter, pressure, typology of valves (remote controlled or not), population and dwelling distribution
around the pipeline.
Corrosion protection:
Buried pipelines are provided with a coating aiming at protecting them against the corrosive action of the
soil into which they are laid down.
Coatings are made of suitable materials having particularly adequate qualifications as far as electric
resistively, adhesion to the steel, plasticity, strength, non-hygroscopicity, impermeability and inalterability
by the aggressive agents of the soil.
Furthermore, the pipeline should be protected against corrosion by means of cathodic protection systems.
The sections of above ground pipelines are protected by means of coating or painting suitable to their
environment.
According to the importance of the pipeline and to relevant internal standards, the line may be pig gable.
The above design element list does not have to be considered exhaustive and each measure could be
implemented according to technical and economical constraints that the designer has to evaluate case by
case.
7.2.5 Design review
The control to be put in practice in the following construction, testing, operation and maintenance can be
considered and defined at each step of design through a preliminary identification of the design phases and of
the potential hazards for safety and environment.
The designer can be internal or an external contractor to the gas operator.
The design can be independently reviewed and approved.
The company organisation warrants the selection of a designer with adequate competencies in order to get a
correct and complete design and to fulfil the accordance with the Environmental and Safety goals of the
management system.
On conclusion of the design, a complete set of documents can be produced containing a description of the
pipeline, drawings, data of pipeline components and structures and other construction information if required
