Author: Gerrit Buchheim and Dave Dewees
Gerrit is a recognized industry expert in damage mechanisms, sulfidation, wet H2S cracking, creep, HTHA, fire assessment, IOW’s, corrosion reviews, RBI, and FFS assessments. With his over 33 years of experience, he has been involved in all aspects of materials engineering including corrosion prevention, failure analysis, fire damage assessment and fitness-for-service assessments in the entire range of fixed equipment primarily in refineries, but also petrochemical units and upstream facilities.
Dave has worked in the petrochemical, nuclear and power industries over the last 16 years. Dave’s specialties include finite element analysis (FEA - heat transfer/thermal-stress, creep, fracture and shock and vibration), fatigue, fracture and creep modeling, as well as computational fluid dynamics (CFD) and multiphysics problems.
He is a long time member of ASME (Sections I, III and VIII) and API committees, as well as AWS (weld residual stress modeling). Dave lives in the Cleveland, Ohio area. where he works out of the Medina, Ohio office.
