2 Presentation Contents Pipeline Integrity Management (PIM) Purpose Scope Why PIM? How Does PIM Work? Typical PIM Plan Contents PIM Reporting

3 Presentation Contents cont d ASME B31.8S Review DS EM Annex II review Implementation Schedule Ongoing Management Observations and Recommendations

4 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 Minimize operating risk to ensure Corporate goals a met

5 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

6 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

7 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

8 How Does PIM Work? cont d 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

9 Typical PIM Plan Contents Introduction Purpose and objectives Corporate policy Governing regulations

10 Typical PIM Plan Contents Organization, Responsibilities and Planning Budgets and resources Records Competency and training Change management Failure and Incident Investigation Communications and reporting Program Audits Organizational responsibilities

11 Typical PIM Plan Contents Hazard Identification and Risk Mitigation Design and Construction O&M Risk Assessment

12 PIM Plan Reports Integrity Management plan must be submitted for OSINERGMIN to review Report on plan changes and progress to be submitted yearly Change Management Continuous Improvement Internal plan audit results

13 PIM Related Reports ROW Stability - Geotechnical River crossing depth of cover surveys ILI and anomaly investigation Corrosion Control Personnel Training Incident reporting and failure investigation Risk Management

14 ASME B31.8S-2004 Managing System Integrity of Gas Pipelines

15 ASME B31.8S Scope Applies to onshore gas pipelines. Designed to provide Operators with information to develop and implement an effective integrity management program.

16 ASME B31.8S Integrity Management Principles Engineered into new pipeline systems Customized to meet unique pipeline conditions Program must be flexible Periodically evaluated and modified to meet changes in operating environment

17 ASME B31.8S Integrity Management Principles Cont d Assessing risks is important Information integration key when performing risk assessments Requires commitment from all operating staff

18 ASME B31.8S Integrity Management Program Elements Integrity Management Plan Performance Plan Communication Plan Change Management Plan Quality Control Control Plan

19 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

20 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

21 ASME B31.8S Communications Plan Plan for effective communication with: Employees The public Emergency responders Local officials Jurisdictional authorities

22 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 implemented Changes to environment in which pipeline operates are evaluated

23 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 Inspections Mitigation activities Prevention activities

24

25 ASME B31.8S Integrity Management Plan Process Flow Identify potential pipeline impact by threat Gather review and integrate data Assess risk Assess integrity

26 ASME B31.8S Integrity Management Plan Process Flow Develop response to integrity assessment including: Repair methods Prevention practices Setting inspection intervals Update, integrate and review data Reassess risk

27 Decreto Supremo EM Reglamento de Transporte de Hidrocarburos por Ductos

28 DS EM Development Previous edition DS 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

29 DS 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

30 DS 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

31 DS 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)

32 DS 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)

33 DS EM Annex II Pipeline Integrity System

34 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.

35 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

36 Annex II Title III Administration Requires the Operator to: Keep records on all aspects of the pipeline s design construction and operation Document procedures for the management of records for the PIMS

37 Annex II Title III Admin. cont d Includes requirements for: Employee training and competence for managing PIMS Procedures to manage changes that could affect the integrity of the pipeline

38 Annex II Title IV Management of the Pipeline Integrity System

39 Annex II Title IV Plans 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

40 Annex II Title IV Plans and Programs cont d Plans and programs documented for OSINERGMIN review Study of historical failure rates

41 Annex II Title IV Plans and Programs cont d Analysis of risks associated with defects in the pipe and their disposition Methods to reduce risk of failure such as additional inspection and patrols

42 Annex II Title IV Patrols, Inspections, Tests and Monitoring Document procedures for: Cathodic protection Internal corrosion/corrosive agents Visual inspection of exposed pipe

43 Annex II Title IV Patrols, Inspections, Tests and Monitoring Document procedures for PIT&M for: ROW patrolling SCADA system Procedures used to Repair defects

44 Annex II Title IV Internal Audits To ensure continuing effectiveness Operator is required to document procedures for: PIM review PIM audit

45 Annex II Title V OSINERGMIN OSINERGMIN is required to supervise the Operator s PIMS Supervision includes determining frequency of its inspections Requirements for reporting, testing and documentation

46 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

47 PIM Implementation Schedule Operator to present OSINERGMIN PIMS implementation program by November OSINERGMIN has 6 months after receipt to approve implementation plan

48 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

49 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

50 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
