This slide presentation outlines an effort to use risk and criticality for asset management of a large-diameter pipeline. The asset management continuous life cycle is presented first, along with the objectives of a large-diameter pipe assessmentprogram that include:failure prevention;which lines to inspect;frequency, technology, cost;which lines to protect;technology, cost, schedule; and,which lines to replace or rehabilitate;technology, cost, schedule. The presentation compares a large-diameter program vs. a small-diameter program. Risk assessment/management is presented in terms of likelihood of failure and consequences of failure. Further topics outlined include: program development for large mains; Examples of Pipe Classification forAssessment Plan Development; Elements of an Assessment Plan; Case Study - DWUInventory of Large Diameter Mains; Recommended Inspection TechniquesPCCP and Steel Pipe; Soil Sampling & Testing; Soil Characteristics; Prioritized 10-Year Program - 36-inch & Larger; Inspection Recommendations & Budgets; Small-diameter vs. Large-diameterBudget Recommendations (10-year average); and, lessons learned. Includes tables, figures.
