AFPM Case Study with Marathon Garyville Refinery

Shane Kling of Ei and Philip Frazier of the Marathon Garyville Refinery co-authored a case study on the cost savings of converting standard refinery piping and instrumentation diagrams (P&IDs) to electronic, "intelligent" P&IDs.

The case study, which was published by the trade organization, American Fuels and Petrochemical Manufacturers, presented cost projection data illustrating a “break-even point” (e.g., where initial and ongoing costs for each method equal one another) of 7 years. A 50% reduction of current industry rates to convert electronic P&IDs, then, would present a break-even point of 3.5 years.

Furthermore, the authors discussed benefits of the technology to non-environmental disciplines, such as Process Safety, Operations, Inspections, and Mechanical Integrity – who all maintain P&IDs for compliance or reference purposes. If non-environmental disciplines were included in a subsequent case study, it stands to reason that greater costs savings can be achieved.

Considering that the PSM regulation mandates P&IDs to be revalidated every 5 years, it is a feasible strategy to consider implementation of intelligent P&IDs alongside P&ID updates resulting from the PHA process.  The case study also demonstrated that mobile technology utilizing electronic P&IDs can result in environmental productivity improvements representing 60% efficiency gains.
