Mr. Feller is a team member of the Mechanical Engineering Business Unit at E2G | The Equity Engineering Group, Inc.  As a member of this team, he performs technical evaluations of in-service fixed equipment in the oil & gas and chemical process industry.  This equipment includes assets such as pressure vessels, piping, and storage tanks.

Mr. Feller performs Fitness-For-Service (FFS) assessments in accordance with API 579-1/ASME FFS-1 to determine the acceptability of damaged equipment for continued operation and provide clients with inspection recommendations and/or cost-effective repair/replace solutions.  He performs FFS assessments to evaluate damage mechanisms such as metal loss, distortion, brittle fracture, stress corrosion cracking, and fatigue.

Mr. Feller also performs Suitability-For-Service (SFS) assessments to evaluate undocumented equipment and establish equipment operating limitations (pressure/temperature) to satisfy jurisdictional requirements.  He also performs rerate assessments in accordance with NBIC and API 510 to alter equipment allowable operating pressure/temperature.

As a part of the vibration field services that E2G offers, Mr. Feller participates in the collection of vibration data as well as the evaluation and processing of the data.  The vibration data is used to offer vibration mitigating solutions to clients while maintaining compliance with ASME piping Codes.
