Senior Discipline Engineer  
Coffman Engineers, Inc., December 1995 to Present, spokane United States
(Consulting, Piping)
With over 30 years of experience in the mechanical engineering field, I have gained industry knowledge, insights, and technical expertise. ASME has been a valuable resource to me throughout my career, and I would like to give back to this community and help ensure that it remains strong for professionals in the future. I am volunteering to share my experience and do the work necessary to maintain the B31.1 Power Piping Code as well as to keep abreast of developments in the piping field. The volunteer role will be helpful as I support multiple engineering offices with ASME B31.1 Code design compliance. I am experienced in the design and upgrade of industrial plants and steam utilities. He specializes in industrial boiler plants, steam distribution piping, district energy systems, industrial design, and construction related services. Previously, he has filled a sustaining role as a maintenance engineer and worked closely with other disciplines such as civil, structural, electrical, and process control. Previous Employment: Bovay Northwest 1994-1996/ Edward Engineering 1993-1994/ Pacific Engineering 1988-1993/ Weyerhaeuser Paper Company 1985-1988 Coffman Engineers 1996-present Supervised engineering of steam infrastructure, industrial boiler plants, piping, natural gas pipeline meter stations, process piping, combustion systems, industrial furnaces, air pollution control, and industrial ventilation projects at a consulting engineering firm. Engineer of Record for multiple projects for a wide variety of clients. This experience has taught me to use a variety of codes and the need for clarity to be in compliance which will be of value to the ASME committee. Additionally, I have gained knowledge on ASME B31.1, B31.3, B31.8, and B31.9, codes, as well as the way these codes are referenced in other codes such as ASCE-7 and state law. Notable recent projects included: Boeing - Everett, WA Steam Distribution: Pipe stress analysis, piping engineering, and design review for multiple steam distribution piping projects at Boeing Everett plant to install 5,200 ft of 200 psi steam distribution utility. This project was challenging because of limited space available for expansion, the owners seismic design requirements, multiple tie in points, and the use of dynamic analysis of the piping for seismic resistance. Boeing Feedwater Pump and Softener Replacement - Auburn, WA: Boiler feedwater pump and water treatment replacement at 450,000 lb/hr central steam plant. Design of this project included application of ASME B31.1 for boiler feedwater piping and water treatment. Replace Feedwater Pumps - Ft. Wainwright, AK: Pipe stress analysis for power plant feedwater pump replacements and design of ball joint arrangement for differential movement of buildings during seismic events. Analysis included ASME B31.1 compliance, and pump flange reaction limitations. Ft. Wainwright, AK: Designed 3,000 linear feet of high pressure steam distribution and condensate collection piping to extend district energy system including 18 new valve vaults. Eastern Washington University - Cheney, WA: Engineer of record for multiple projects at central steam plant and district energy valve replacements, condensate pump replacements, and pressure control valve replacements. SGL Automotive Carbon Fibers Phase 3 - Moses Lake WA: Prepared piping, valve, and other technical specifications for new carbon fiber production plant. F-35 Program Eielson Air Force Base, AK: Supervised design and analysis of 1,800 ft of high pressure steam distribution and condensate collection to extend district energy system to two new hangars, and four other buildings in the F-35 program. The team utilized finite element analysis for optimization of anchor reactions at concrete vault floors. TransCanada Natural Gas Meter Stations, Multiple Projects, Nationwide
