Mr. Rettig is currently Vice President of Power Generation and has responsibilities for
marketing and engineering power plant projects worldwide. Areas of expertise include asset
evaluation, life management, failure analysis of power plant, automotive, and aircraft
components; materials selection and methods of fabrication and processing; corrosion and
metallurgical failure of alloys; nondestructive inspection by acoustic emission; and
preparation and examination of metallurgical specimens.
Experience includes developing and implementing analytical and experimental methods for
determining conditions and remaining useful life of equipment with emphasis on power
plants.
Recent work includes creep damage and remaining life of superheater and reheater tubes;
failure analysis of nuclear and fossil power plant components, including turbine blades,
shafts, boilers, discs, pulverizers, waterboxes, and steam generators; analysis of failure data
to identify recurrent and generic problems; failure analysis and materials selection for
sewage sludge heat exchangers; analysis of reheat cracks and review of weld procedures;
accident reconstruction; and metallographic and fractographic analyses.
