Summary:

Reliability and Maintainability of In-Service Pipelines helps engineers understand the best structural analysis methods and more accurately predict the life of their pipeline assets. Expanded to cover real case studies from oil and gas, sewer and water pipes, this reference also explains inline inspection and how the practice influences reliability analysis, along with various reliability models beyond the well-known Monte Carlo method. Encompassing both numerical and analytical methods in structural reliability analysis, this book gives engineers a stronger point of reference covering both pipeline maintenance and monitoring techniques in a single resource.- Provides tactics on cost-effective pipeline integrity management decisions and strategy for a variety of different pipes- Presents readers with rational tools for strengthening and rehabing existing pipelines- Teaches how to optimize materials selection and design parameters for designing future pipelines with a longer service life
