ARPEL = Regional Association of Oil, Gas and Biofuels Sector

Companies in Latin America and the Caribbean

Created in 1965, its members represent over 90% of the

upstream and downstream activities in the region.

ARPEL fosters and facilitates industry development and

integration, continuous operational development and effective

management of environmental and social issues

Pipelines that have been in service for a number of years

represent a challenge to pipeline operators worldwide.

This paper describes the basics of the ARPEL Reference

Manual for Pipeline Integrity Management as well as

ARPEL efforts to build the capacity and disseminate its

use throughout Latin America and the Caribbean.

The Manual provides ARPEL Member Companies with a

set of referential instructions and procedures that may

be modified to adapt them to the specific situation of

each company and to the applicable legal or corporate

regulations.

Step 3 Failure modes

Describes the different threats that may affect the pipeline integrity and failure

mechanism.

1. Internal corrosion

2. External corrosion

3. Natural forces

4. Third-party actions

5. Operational errors

Step 4 Action plans and maintenance program

Action plans to mitigate risks Definition of the

techniques and/or methodologies and frequency

of inspection, monitoring and mitigation.

Risk re-assessment and changes to the action

plan Risk assessment should be a continuousprocess.

Management of change in a pipeline integrity

program Once a pipeline integrity program is

established and during its application.

Step 5 Integrity Program Evaluation

Performance indicators It is necessary toestablish and measure the performance indicators

to know if the action plan was applied and the

effectiveness of such plan.

Audits Audits of integrity management program

are an important element of evaluating program

effectiveness.

Continuous performance improvement Since

the details of the operator integrity management

program will vary.

ARPEL Program:Assessors Accreditation in Pipeline Integrity Management

Objective: Accredit assessors of pipeline integrity

management programs in Latin America and the Caribbean

through the implementation of the ARPEL manual.

Courses: Theoretical and practical field work at centers of

excellence (CTDut, Corporate University of Ecopetrol, etc.)

Focus: Specific failure modes (e.g., corrosion, third partyactions, etc.). Assessors may apply for accreditation in more

than one threat.

Targets: Experts from ARPEL member companies, who will

be trained by a group of experts from the Region.

Start date: March/201212

Conclusions 1 of 2

ARPEL Reference Manual for Pipeline Integrity Management

compiles the best practices from companies experienced in addressing

the main failures modes in Latin America and the Caribbean.

Although the ARPEL Manual requires adaptation to national/local

legislation, it sets unified management criteria that support the

operational, environmental and social excellence of pipeline

operations, thus setting the basis for regional cooperation.

Conclusions 2 of 2

The implementation of the ARPEL Manual will allow to have a

structured diagnostic and to devise mitigation activities that optimize

operators resources , improving their business efficiency.

The ARPEL Program of Assessors Accreditation in Pipeline Integrity

Management will be the ONLY one in the Region. It will spread

knowledge and best practices, addressing one of the most pressing

issues in the industry today: maintaining a high level of human talent

and competence.
