Alan Werner’s skills and background include forensic analysis in the areas of industrial process systems, industrial process equipment including pumps, fans, heat exchangers, mixers, specialty equipment, piping include safety devices, and pipe support systems. Specific experience has been gained in chemical process plants, pulp and paper mills, wood processing plants, boiler plants, chiller plants, and co-gen systems and food processing plants. Using a proprietary thermodynamic model, he is able to replicate boiler and chiller systems to duplicate normal and off-spec operations. I have designed mechanical parts and machinery, some using unusual materials and/or features. I have experience in worker sound exposure investigation and remediation, as well as "fence line" acoustical research. Trained for patent litigation. My professional licenses are in Washington, California, Florida (Ret), and British Columbia (former).
