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 through 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.
