Residual Lifetime Assessment

Optimized Pipeline Management

As a pipeline operator, you have a significant investment in your buried infrastructure. As this infrastructure ages, maintenance, repair and replacement can represent a significant expense. Maximizing your capital spending programs, while ensuring system integrity, is a key focus. One of the keys to developing optimized capital expenditure programs is having detailed system knowledge and knowing what sections of the pipeline need to be replaced when.

The 'Missing-Link'

For many sections of the pipeline, however, detailed information regarding the condition of the pipeline and, more specifically, the residual lifetime of the pipeline is not available. This is the 'missing-link' in being able to develop optimized capital investment programs.

There is generally a lack of information regarding the specific condition of a buried pipeline. Specifically, the residual lifetime is not known. This is because, for plastic piping materials, all material performance is different and the specific application has a big influence on performance. There is no general model of lifetime for plastic piping materials and, hence, no easy tool for operators to use to forecast the lifetime of their piping systems.

How then, given this general scarcity of information, do operators cost effectively forecast the residual lifetime of their plastic piping systems?

Residual Lifetime Forecasting Methodology

Jana has developed a Residual Lifetime Forecasting Methodology for plastic piping systems that enables projection of performance for each segment of your pipeline. Through exhumation and accelerated testing and the application of Jana's Lifetime Forecasting Models, you are provided with the tools to project how your system will perform into the future.

There are three components to the Jana Residual Lifetime Forecasting Methodology:

1. Initial System Review
   1. Engineering review of system
   2. Set-up of Analysis Approach
   3. Development of Material Sampling Plan
2. Residual Lifetime Modeling
   1. Accelerated Testing of Field Specimens
   2. Life-time Forecast Modeling
   3. Correlation Modeling
3. System Lifetime Engineering Assessment
   1. Lifetime Forecast by Segment
   2. Repair/Replacement Prioritization
