Course Description
Gain an Understanding of the DBA Methods
The new ASME Boiler & Pressure Vessel Code, Section VIII, Division 2 was published on July 1, 2007. This 2007 Edition became mandatory for vessel design in July, 2009. The new Division 2 includes a complete re-organization of the text, introduces a consistent and user-friendly format style, and provides a number of new and enhanced pressure vessel design procedures. The new Design By Analysis (DBA) requirements in Part 5 of Division 2 introduce many of these new procedures involving load combinations, stress analysis, and fatigue evaluation. The understanding and application of these rules is essential to both the new and experienced vessel engineer to ensure proper vessel design.
Pressure Vessel: Design by Analysis Methods provides the vessel engineer an in-depth examination of the techniques used in DBA pressure vessel design through numerous example problems. ASME contracted Equity to write PTB-1-2009 Section VIII - Division 2 Criteria and Commentary and PTB-3-2009 Section VIII - Division 2 Example Problem Manual because our engineers were instrumental in the development of this new code and have years of experience in the design and analysis of pressure vessels for owner-users as well as in a consulting capacity.
This course includes discussions on general requirements for numerical simulation using Finite Element Analysis (FEA); material modeling requirements for use with FEA; design load combinations for pressure vessel design; design for protection against plastic collapse using elastic stress analysis, limit load, and elastic-plastic stress analysis; background and requirements for the new strain limit criterion; buckling analysis types and differences in design margins; fatigue analysis using smooth bar and welded joint technology in the new structural stress approach; ratcheting assessment using both elastic and elastic-plastic analysis; and a special emphasis on the evaluation of thermal stresses.
The focus of the course is to provide an understanding of the analytical methods in the new Division 2 as well as to convey practical information on how to meet Part 5 requirements of the new Division 2 using FEA codes.
Course Methodology
This specialty course consists of lectures that cover DBA in detail. Example problems demonstrating concepts in the new Code will be shown by instructors who helped develop the Codes, with portions worked by the students. PTB-1-2009 Section VIII - Division 2 Criteria and Commentary and PTB-3-2009 Section VIII - Division 2 Example Problem Manual will be extensively used. In addition, numerical simulations using FEA illustrating design approaches will be demonstrated during the course and critiqued by class participants.
This course is a detailed extension of an introductory overview course on the new Division 2 that is also offered by Equity. Pressure Vessels: The New Division 2 Rules is a 3.5-day course that covers all Parts of the 2007 Edition of Division 2, including the Design by Rule (DBR) methods.

Who Should Attend
This course is intended for pressure vessels engineers working for manufactures or engineering and design construction firms in the refining/petrochemical and comparable industries, and engineers for Owner-Users that desire a practical understanding of one of the major areas of the new Division 2.
FFS engineers who perform Level 3 assessments will also find the course beneficial since Part 5 of Div 2 is harmonized with Annex B1-B4 of API 579-1/ASME FFS-1.
