Forensic Engineering Investigations

While at Knott Laboratory and formerly Engineering Design & Testing Corp., Mr. Mowry has conducted numerous forensic engineering investigations including those related to personal injury and property damage. His investigation experience included product liability investigations, premises liability investigations, workplace safety investigations, heavy equipment investigations, and others. His investigative experience has involved subjects such as boilers, furnaces, bolted connections, pipes, dishwashers, fire suppression systems, heavy machinery, agricultural equipment, cranes, scaffolding, and more. At Knott Laboratory he participates in investigations of complex motor vehicle accidents as well as performing complex accident reconstruction and visibility studies.

Failure Analysis

Mr. Mowry has conducted multiple failure analyses on various components including plumbing fittings and fixtures, PVC piping, copper and iron water piping, gear teeth, bearings, and other components. Through Mr. Mowry’s education and experience, he frequently examines mechanical systems and components and determines the root cause of failure, including failure to maintain, improper use, long term wear and tear, and design or manufacturing defects.

Expert Testimony

As a result of Mr. Mowry’s investigations and analyses, he has provided expert witness testimony in both state and federal court. Mr. Mowry’s work has been for both plaintiffs and defendants in the areas of mechanical engineering.

Engineering and Design

While at Iofina Resources, Inc., Mr. Mowry oversaw the design, installation, and improvement of multiple iodine extraction facilities located on salt water disposal facilities in the mid-stream oil and gas fields in northwestern Oklahoma. He performed equipment sizing and hydraulic analyses for pumps and piping systems, including acidic and caustic fluid handling systems. Mr. Mowry worked closely with project scheduling and budgeting through the design, construction, and commissioning of the facilities. While at Shaw, Stone, & Webster, he also was involved in multiple multimillion-dollar projects including overseeing the design, management, implementation, and start-up of multiple heavy equipment replacement projects at an operational nuclear power generation facility. His work at Shaw, Stone, & Webster included the replacement of the high-pressure turbine, condensate pumps and motors, low and high-pressure feedwater heaters, isolated phase bus duct cooler, main feedwater pumps and motors, and main steam and feedwater pipe support upgrades. In addition, Mr. Mowry oversaw multiple licensing and design basis evaluation projects for nuclear safety related equipment at an operational nuclear power generation facility. He performed federal regulatory evaluation and industry code evaluation for mechanical systems including the auxiliary feedwater systems, containment fan cooling units, and the containment spray system. In addition, Mr. Mowry was the author of a license amendment request submitted to the Nuclear Regulatory Commission to revise the licensing basis for the nuclear facility.
