Overview:

Mr. Schaser focuses on using the Finite Element Approach (FEA) to perform Level 3 evaluations of pressure-containing equipment and components in accordance with API 579 assessment methodology.  Mr. Schaser performs finite element stress analysis, Fitness-For-Service (FFS) evaluations of in-service equipment, remaining life assessments, and ASME Code design of pressure-containing equipment.  He also performs pressure vessel design calculations and Level 2 and Level 3 FFS assessments.  In conjunction with his code calculation and FFS capabilities, Mr. Schaser provides engineering turnaround (TAR) support.

As an entrepreneur, outside his employment with E2G, Mr. Schaser has developed new technology to remove samples from the surface of metal plates (The Saxon Sampler).  This technology is used to acquire samples from reactor walls to generate full-size test specimen for tensile and toughness tests.  The information gained from the testing is used to confirm or establish material properties used in the design of pressurized equipment.  Reduction in strength and toughness may occur under certain operating conditions (high heat, hydrogen environment, etc.) which may lead to a reduction in the design safety factor of the equipment.  Confirmation of material properties reassures clients that they are operating within design code limits or identifying the need for remediation.  Mr. Schaser’s efforts have afforded him a U.S. Patent.

Prior to Mr. Schaser’s arrival at E2G | The Equity Engineering Group, Inc., he worked for 12 years as an analytical chemist for General Electric’s Lighting Division.  He specialized in x-ray diffraction and x-ray fluorescent spectroscopy.
