    Result: Corrective and preventative manufacturing practices were implemented to cease production and recall affected products, preventing future contaminations and ensuring compliance with consumer safety expectations.

  • waste-to-energy technology and equipment

    Technology and Equipment Provider for Renewable Waste-to-Energy Facility

    Challenge: A renewable municipal waste-to-energy technology and equipment provider faced allegations of design defects, including faulty equipment, poor operational controls, unwanted byproducts, and inconsistent environmental emissions.

    Solution: EPS conducted a detailed engineering analysis of the technology and equipment to determine and confirm its superior performance while identifying severe issues with the owner’s equipment, processing out-of-specification waste materials, poor water treatment, and unreliable environmental controls.

    Result: EPS determined the root causes of the owner’s operational issues, enabling effective operational changes and eliminating alleged rectification works and damages, thereby saving substantial costs for the technology provider and facility owner.

  • steel mill facility

    Technical Investigation and Financial Appraisal of Equipment Failure and Facility Shutdown

    Challenge: A steel mill facility experienced chronic materials handling and operational issues, including a catastrophic collapse and shutdown during a severe snowstorm.

    Solution: EPS conducted a thorough engineering and equipment maintenance assessment, including site inspections and a appraisal of the equipment and blast furnace operations. .

    Result: The evaluation determined negligible damages to the client, a controls and equipment supplier, providing a clear quantification of risks for the resolution of the dispute through impartial engineering and appraisal analysis.

  • energy technology developer

“John and his team are amazing. They took one of the most scientifically complicated cases I’ve ever been involved in and truly figured out what happened. That was hard enough to do, but perhaps where they really shined was in explaining that science — first to me so that I could effectively question witnesses, and then in deposition — in a way and at a level that those of us who are not engineers could understand and follow.”
