  • Oakland

Dr. Inkabi has over 10 years of experience specializing in the risk assessment and management of infrastructure systems with a particular emphasis on human and organizational factors. He has completed a full range of risk and reliability studies including uncertainty and risk analyses of natural gas pipelines, vulnerability assessments of flood control and power transmission systems, and the evaluation of high reliability management practices (nuclear power industry). He also worked on the development of engineering quality metrics, including safety, resilience, and sustainability. In addition, he participated in the National Science Foundation sponsored investigation of the New Orleans flood defense system following Hurricane Katrina in 2005.

Dr. Inkabi has experience consulting on pipeline safety and integrity management issues to gas transmission and distribution companies, including a large gas utility company with its implementation plan to validate the Maximum Allowable Operating Pressure (MAOP) and modernize records for its gas transmission lines. He has performed formal apparent cause evaluations (ACE) and root cause analyses (RCA) in response to gas safety and reliability events.

Project Experience

Directed a review of a Stage 3 pipeline risk analysis in Marysville, California. Reviewed a site-specific risk analysis of two natural gas pipelines to a nearby school site, including proposed mitigation measures.

Performed human factors focused vulnerability evaluation of the Electric Reliability Council of Texas’ transmission system. This project consisted of building a conceptual infrastructure and human performance models, defining quality metrics, estimating error rates, and lastly partnering with Los Alamos National Laboratory to conduct an advanced Monte Carlo simulation of the ERCOT system to understand the potential affect repair crews and control room operators have on serviceability and resilience.

Evaluated burst limit state models for corroded oil and natural gas steel pipelines. For this project, 153 experimental and in-service pipeline failures were complied, evaluated and verified in order to estimate the epistemic uncertainty and overall suitability various industrial and academic internal pressure limit state models for corroded line pipe reliability evaluations.
