The pipeline management integrity plan has as the principal purpose to organize all the
actions of monitoring, evaluation and mitigation in order to avoid the consequences associated
with failures of the systems and / or the total replacement of the installed pipeline. Experiences
in a field with severe external and internal corrosion in the east of Venezuela show excellent
results using integrity management practices that have allowed extending the useful life of
several systems of pipelines assuring their integrity throug h repairs and mitigation actions.
This paper describes the following three field experiences:
· 180° Rotation of 10 Km of pipeline with internal damage produced in less than 16
months of operation. This work covers the actions of monitoring, evaluation and
mitigation implemented to guarantee the pipeline integrity and life extensions. An
optimization and redesign of the chemical treatment implementation is also covered in
the present work. Estimated useful life of the pipeline was extended by 8 years.
· Repair and reinforcement with metallic and fiber glass sleeves on a water injection
pipeline with several external damages. The process of evaluation and monitoring that
allowed to determine the points to be repaired are described. Estimated useful life of the
pipeline was extended by 10 years
· Repair and reinforcement of welds of a 3 Km pipeline that presented a series of failures
in the welds caused by and inappropriate welding process. Estimated useful life of the
pipeline was extended by 10 years
The cost of the reparations work done was equivalent to only 2% of the cost of the total
replacement of the damaged pipelines.
