David Osage, P.E., ASME Fellow

With over five decades of experience in the refining and petrochemical industry, David Osage has established himself as a trusted consultant and industry expert.  His career has been defined by his work in engineering consulting for pressure-containing systems, including pressure vessels, piping, and storage tanks.  He has a profound specialization in areas such as stress and thermal analysis, advanced finite element methods, and high-temperature design.  His expertise extends to Fitness-For-Service (FFS) assessments, fracture mechanics, failure analysis, and evaluating the remaining life of in-service equipment.

David has played a critical role in problem-solving and operational support, offering practical solutions for equipment failures, design modifications, and repair strategies during shutdowns and maintenance.  He has been instrumental in the development and implementation of Computer-Aided Engineering (CAE) systems tailored for plant engineering and has refined engineering standards and QA/QC procedures for capital projects.  His ability to troubleshoot and recommend actionable repair solutions for damaged equipment has been invaluable to the facilities he has supported.

In capital project management, David has excelled by preparing design specifications, coordinating design reviews, and ensuring the development of robust engineering standards.  His comprehensive knowledge of refinery and petrochemical plant equipment and processes has been a cornerstone for delivering successful outcomes on complex projects.

As an educator, David has dedicated himself to advancing the skills of practicing engineers.  He has designed and delivered industry training courses on Fitness-For-Service and related technologies.  As an Adjunct Visiting Assistant Professor at Stevens Institute of Technology, he taught graduate-level courses in strength of materials, elasticity, structural analysis, finite element methods, and structural optimization.  His commitment to knowledge transfer and professional development has left a lasting impact on the engineering community.

David is internationally recognized for his leadership in the development and application of Fitness-For-Service technology.  As the architect and principal investigator of API 579-1/ASME FFS-1 Fitness-For-Service, he pioneered numerous assessment methodologies and established the technical foundation for the standard.  For his contributions, he received a Certificate of Appreciation from API.  Serving as chairperson and vice-chairperson of the API/ASME Joint Committee on Fitness-For-Service, David was instrumental in the update to API 579-1/ASME FFS-1 Fitness-For-Service.  He also contributed to the API 579-2/ASME FFS-2 Fitness-For-Service Example Problems Manual, earning him a Resolution of Appreciation from API and a Certificate of Acclamation from ASME.

His expertise extends to the design of new equipment.  As the lead investigator and principal architect of the 2007 Edition of ASME Boiler & Pressure Vessel Code Section VIII, Division 2 – Alternative Rules, he introduced a modernized organization and writing style.  He incorporated advanced technologies, such as updated material behavior models, innovative brittle fracture evaluation methods inspired by API 579-1/ASME FFS-1, and updated design-by-rule and design-by-analysis procedures. Notably, he introduced elastic-plastic analysis methods and a new fatigue evaluation methodology for welded joints.  For these transformative contributions, ASME recognized him with a Certificate of Acclamation.

At ASME’s request, David authored PTB-1-2014 ASME Section VIII Division 2 Criteria and Commentary, a comprehensive technical overview of the code.  He also co-authored PTB-3-2013 ASME Section VIII – Division 2 Example Problems Manual and PTB-4-2013 ASME Section VIII – Division 1 Example Problems Manual, offering real-world examples to guide proper application of these codes.  He has served in leadership roles on the ASME Board on Pressure Technology Codes and Standards, as well as on several Section VIII committees, including the Main Committee, Subgroup Design, and Subgroup on Fabrication and Inspection.  For his significant contributions, Mr. Osage was named an ASME Fellow in 2016.

A pioneer in Risk-Based Inspection (RBI) technology, David led the revamp of API 581 Risk-Based Inspection Technology, Second Edition, which involved a clean-sheet rewrite and the development of a new API RBI software version.  Currently, he is advancing the next generation of RBI technology by integrating Fitness-For-Service assessment procedures to calculate the probability of failure, further enhancing risk-based decision-making.

As an educator, David is a lead instructor for the ASME MasterClass Series, offering advanced training in Design-By-Analysis, Fitness-For-Service, and Repair.  These courses emphasize practical applications and real-world case studies, providing experienced professionals with innovative expertise.  His extensive technical knowledge and proactive hands-on experience make him a sought-after authority in these fields.

David serves as Chairperson of the Board of the Welding Research Council (WRC), which includes the Materials Properties Council (MPC) and the Pressure Vessel Research Council (PVRC).  These organizations, founded over a century ago by the Engineering Foundation, have long supported industry needs in material properties and performance.  David is dedicated to preserving and sharing the extensive technological data and insights developed by these councils, ensuring their continued relevance and benefit to the industry.
