Qualifications

Mr. Wahl joined Kiefner & Associates, Inc. in 2007.  He has contributed to a broad range of pipeline-related projects.

Relevant Experience

Defect Assessment/Pipeline Integrity. Calculated remaining strength and expected failure pressures for various defects.

Calculating Remaining Life (Fitness-for-Service) and Reassessment Intervals and Inspection Intervals. Established hydrostatic test and in-line-inspection intervals for liquid pipelines to reduce the risk of pressure-cycle-induced fatigue failures.

Stress Analysis. Calculated stress due to heavy equipment traversing over buried in-service pipelines.  Analyzed pipelines for stresses induced by external loadings due to spanning, and soil movement due to subsidence or settlement. 

Finite Element Analysis. FEA can be used to calculate stress due to loading and evaluate the effects of metal los and mechanical damage.
