John Aumuller is a Senior Engineering Advisor at Carmagen Engineering Inc., a member of Mistras Group. He has more than 30 yr of experience in the design, maintenance and fitnessfor- service evaluation of pressure equipment; the fitnessfor- service determination of delayed coker drums have been a particularly challenging problem. He has taught courses in finite element analysis, refractory systems, pressure piping and pressure vessel code design, inspection and maintenance throughout the US, Europe and the Middle East. Dr. Aumuller holds a BSc degree in mechanical engineering from the University of Waterloo, Ontario, and an MSc degree and a PhD from the University of Alberta, in Canada.
