Static and Cyclical Dents Assessment
Are Pipeline Dents Causing You Stress?
Mechanical damage can result in immediate pipeline failure — but not always. Dents might be below the failure condition at the time of impact but can grow through cyclic pressure until they become a “delayed threat” to pipeline integrity.
Approach
Three Levels of Assessment
A three-level assessment provides insight into future integrity and pressure cycling of pipeline dents. We use the in-line inspection (ILI) dent profile and calculated strain to begin the prioritization process. The next step looks at the constraint, acuteness and both static and cyclic loading. If it’s needed, a finite element analysis and fatigue assessment can be conducted.
Value
Setting the Right Priority
We provide everything from a simple priority ranking enabling optimized dent repairs to a full-level analysis for critical dents where accessibility makes repair difficult. Plus, we provide recommendations on future operating conditions.
