Ms. Smith is the head of the Pressure Vessel and Tankage Group within the Mechanical Engineering Business Unit of E2G | The Equity Engineering Group, Inc. Ms. Smith provides Fitness-For-Service evaluations in accordance with API 579-1/ASME FFS-1 to extend equipment life as well as analysis of pressure containing equipment to evaluate mechanical integrity and improve availability. Ms. Smith performs Level 3 assessments using Finite Element Analysis (FEA) simulation methods. She specializes in fracture analysis with research in the development of criteria for crack propagation in complex stress fields.


Since joining Equity, Ms. Smith has performed advanced FFS assessments including pressure vessel fatigue life evaluations, overpressure incident investigations, and critical flaw sizing assessments. She also is an instructor for the SagePlusTM training course providing training specific to the SagePlus suite of analytical tools used to evaluate pressure containing equipment, such as process vessels, piping, and storage tanks. Overall, she uses advanced engineering principles and technologies to provide cost-effective solutions in accordance with industry standards.
