Document Summary
Asset classes: transmission pipelines, distribution pipelines, compression processing facilities, measurement control facilities, storage (winter when usage and demand increases) Inherent risk of transporting gas under high pressure in pipe with high diameter. Time independent threats (human, weather, operation error, third party dig ins) stable threats (equipment related), time dependent threats (corrosion) Phase 1: descriptive analytics, condition of pipelines historically. Phase 3: chance that flaw will lead to rupture or gas leak in pipe. Phase 4: how many people are living near pipeline - safety and reliability environment impact (consequences side), occupancy count based on rupture radius of pipeline (based on flux, diameter of pipe) Phase 5 and 6: prescriptive analytics, how to reduce risk of corrosion, to reduce likelihood or consequences side of risk, how to manage investment, simulate mitigation impacts to quantify risk reduction. Turns and bends: mitigation to make lines more pickable. Value of information - what is it worth to us to make lines more pickable.
