His responsibilities include stress and thermal analysis of pressure vessels, piping, and tankage; development and maintenance of Computed Aided Engineering (CAE) systems for plant engineering; advanced finite element methods; Fitness-For-Service analysis of in-service equipment; high-temperature design and remaining life assessment; fracture mechanics; failure analysis and resolution of lessons-learned; development and maintenance of engineering standards; implementation of design changes and problem-solving at shutdowns; and troubleshooting and recommendations for repairs to damaged equipment.

Mr. Osage provides engineering consulting for all levels of refinery capital projects including preparation of design specifications, coordination of design reviews, development of engineering standards for refinery equipment, and QA/QC procedures for project administration. He also has extensive experience in the preparation and delivery of training courses to practicing engineers in industry-related technologies such as Fitness-For-Service. As an Adjunct Visiting Assistant Professor at Stevens Institute of Technology, Mr. Osage taught graduate-level courses in the strength of materials and elasticity, structural analysis and finite element methods, and structural optimization.

Mr. Osage is internationally recognized as an industry expert and leader in the development and use of FFS technology. As the architect and principal author of API 579 Fitness-For-Service, he developed many of the assessment methodologies and supporting technical information. Mr. Osage was the recipient of a Certificate of Appreciation from API for his work on API 579. Mr. Osage has served as the chairperson and vice-chairperson for the API/ASME Joint Committee on Fitness-For-Service and was instrumental in completing the update to API 579 titled API 579-1/ASME FFS-1 Fitness-For-Service. For his efforts on API 579-1/ASME FFS-1 and API 579-2/ASME FFS-2 Fitness-For-Service Example Problems Manual, Mr. Osage received a Resolution of Appreciation from API and a Certificate of Acclamation from ASME.
