PIM System Goal
To ensure protection of the public and the environment by continuously managing threats to pipeline integrity
Show operator compliance with Annex II of DS 081-07
Minimize operating risk to ensure Corporate goals a met
PIM Scope
Applies to all pipeline systems that transport natural gas and petroleum liquids
Pipeline system includes all parts of physical facilities through which gas and liquids are transported: Line pipe Valves Compressor, meter and delivery stations Liquid pump stations and tank farms
Why PIM?
Operators recognize serious potential consequences of pipeline operations
PIM enables operator to demonstrate to OSINERGMIN that pipeline and facilities are: suitable for initial commissioning safe and reliable for service years after they
have been put into service
How Does PIM Work?
PIM employs a systematic, integrated approach to manage the long term safety and integrity of pipeline systems
Through operating history, potential threats to safe and reliable pipeline operation are identified and mitigated
How Does PIM Work? contd
Management systems and programs form the foundation of integrity management records management condition monitoring data analysis mitigation programs developed in response to
hazards presented to the pipeline

Integrity ManagementProgram Elements
ASME B31.8S
Integrity Management Plan includes: Description of risk analysis method Documentation of data for each section Analysis for determining assessment intervals
and mitigation methods Performance matrix that confirms performance
based options
ASME B31.8S
Performance Plan - Requires operator to: Collect performance information Periodically evaluate success of program Evaluate effectiveness of its management
systems and processes Evaluate new technologies for use in the
program
ASME B31.8S
Communications Plan Plan for effective communication with:
EmployeesThe publicEmergency respondersLocal officials Jurisdictional authorities
ASME B31.8S
Change Management Plan Pipeline systems and operating environment
seldom static. Plan includes a systematic process to ensure
that risks associated with: changes to the pipeline system are evaluated before
being implementedChanges to environment in which pipeline operates
are evaluated
ASME B31.8S
Quality Control Plan Includes documentation for integrity
management plan Allows operator to demonstrate that they meet
requirements of integrity management program Requires integrity program audit including:
Processes InspectionsMitigation activitiesPrevention activities
ASME B31.8S Integrity Management Plan Process Flow
Identify potential pipeline impact by threat Gather review and integrate data Assess risk Assess integrity
ASME B31.8S Integrity Management Plan Process Flow
Develop response to integrity assessment including:
Repair methodsPrevention practicesSetting inspection intervals
Update, integrate and review data Reassess risk
Decreto Supremo 081-2007-EMReglamento de Transporte de
Hidrocarburos por Ductos
DS 081-2007-EM Development
Previous edition DS 041-99-EM did not include specific requirements for pipeline integrity management plan
Regulators (US &Canada) started to require pipeline operators to have integrity plans
OSINERG started to prepare requirements with support from CIDA
DS 081-2007-EM
Establishes regulations and standards for the transportation of hydrocarbons by cross country pipelines
Regulation Includes provisions: To grant Concessions To establish Transportation Service Conditions To establish Transportation Rates To establish and safety regulations To establish environmental regulations
DS 081-2007-EM
Includes 4 Annexes I - safety provisions for design, construction,
operation and abandonment of pipelines II - new requirements for pipeline integrity
management III - scope diagrams from B31.4 &B31.8 IV - emergency procedures
DS 081-07 Gives OSINERGMIN
Authority to Supervise/Oversee: Compliance with the safety regulations for
design, construction, operation, maintenance and abandonment of the pipeline (Article 70 b)
Establishment and execution of pipeline integrity system (Article 70 e)
DS 081-07 Gives OSINERGMIN
Authority to Request Reports from the Operator: technical information in the form it requests
(Article 36 g) the information it requires for the compliance of
its functions (Article 37) The integrity system reports and documents
(Annex II Article 24)
DS 081-2007-EM
Annex II Pipeline Integrity System
ANNEX II Title I General
Requires the Concessionaire to develop and implement a pipeline integrity management system to prevent failures and thereby: ensure the safety of the public protect the environment.
The PIMS is risk based and applies to areas of high consequence.
ANNEX II Title II Scope
Operator must include: A physical description of pipeline function
capacity and location A description of its geography and zones of risk Who in their organization is responsible for all
aspects of the PIMS
Annex II Title III Administration
Requires the Operator to: Keep records on all aspects of the pipelines
design construction and operation Document procedures for the management of
records for the PIMS
Annex II Title III Admin. contd
Includes requirements for: Employee training and competence for
managing PIMS Procedures to manage changes that could affect
the integrity of the pipeline
Annex II Title IV
Management of the Pipeline Integrity System
Annex II Title IVPlans and Programs
Determination and revision of High Consequence areas
HAZOPS/mitigation Remediation of unsatisfactory conditions Procedures to inform DGH, OSINERGMIN Methods to plan and prioritize PIMS
activities
Annex II Title IVPlans and Programs contd
Plans and programs documented for OSINERGMIN review
Study of historical failure rates
Annex II Title IVPlans and Programs contd
Analysis of risks associated with defects in the pipe and their disposition
Methods to reduce risk of failure such as additional inspection and patrols
Annex II Title IV Patrols, Inspections, Tests and Monitoring
Document procedures for: Cathodic protection Internal corrosion/Corrosive agents Visual inspection of exposed pipe
Annex II Title IV Patrols, Inspections, Tests and Monitoring Document procedures for PIT&M for:
ROW patrolling SCADA system Procedures used to Repair defects
Annex II Title IV Internal Audits
To ensure continuing effectiveness Operator is required to document procedures for: PIM review PIM audit
Annex II Title V OSINERGMIN
OSINERGMIN is required to supervise the Operators PIMS
Supervision includes determining frequency of its inspections Requirements for reporting, testing and
documentation
Annex II Title VI High Consequence Areas Determined in several ways:
Class 3 or 4 locations are considered high consequence areas
Locations inside the Area of the Circle of Impact that has a specified number of occupied buildings
PIM Implementation Schedule
Operator to present OSINERGMIN PIMS implementation program by November 2008.
OSINERGMIN has 6 months after receipt to approve implementation plan
Annex II Ongoing Pipeline Integrity Management By actively managing threats to integrity, a
pipeline will remain in good condition for many years
Operators must take integrity matters seriously and aggressively manage risks
Observations and Recommendations Article 21 Annex I requires that high
consequence areas have a SCADA but SCADA must apply to the whole pipeline
Article 1 Annex II indicates that PIMS applies only to high consequence areas but should apply to entire pipeline
Article 94 defines the ROW as 12.5 meters on each side of center line of pipe making maintenance difficult
Observations and Recommendations Important to appreciate everyone's role
responsibilities Operator has the total responsibility for the
safety and integrity of their pipeline OSINERGMIN has the responsibility to
oversee and supervise the application of the regulations
