What Engineering Dynamics Inc. does

Engineering Dynamics Incorporated (EDI) is an independent engineering consulting firm founded in 1982 in San Antonio, Texas by a core group of six engineers. The firm specializes in vibration analysis, pulsation control, rotordynamics, and machinery diagnostics for industrial clients in oil and gas, petrochemical, refining, power generation (including nuclear), water and wastewater treatment, pulp and paper, mining, and cement. EDI delivers solutions through four service lines: Field Testing & Diagnostics (on-site measurement and data acquisition covering reciprocating and rotating equipment), Analytical Services (computational modeling including API 618/674 pulsation studies, torsional vibration analysis, rotordynamics, and ANSYS-based finite element analysis), Equipment Expertise (analysis of pumps, compressors, turbines, and structures across machinery types), and Specialized Services (expert witness work, design audits, and custom software development).

The firm's underlying technology stack centers on proprietary digital acoustical simulation software (in continuous use since 1985), time-domain simulation software for compressor and pump dynamic analysis (since 1995), and a proprietary data acquisition system capable of simultaneous monitoring of over 128 channels. This software is paired with a large inventory of diagnostic instrumentation (accelerometers, proximity probes, pressure transducers, torsiographs, strain gages, and custom shakers). EDI is an active member of API 618 and API 674 sub-task forces on vibration control for reciprocating compressors and pumps, giving it influence over the industry standards it helps clients comply with.

EDI operates as a B2B professional services firm on a project-based, quote-driven engagement model with no publicly disclosed pricing. The company sells through direct enterprise engagement, supported by an extensive library of 80+ technical publications, conference participation (notably the Turbomachinery Symposium at Texas A&M), and recurring short courses. Its customer base spans municipal water authorities (King County, SNWA, Tarrant County, Boston, Honolulu, Puerto Rico), shale operators across the Eagle Ford, Permian, Marcellus, Bakken, Barnett, Jonah, Uinta, and Piceance basins, the Alaska Pipeline, offshore platforms worldwide, and reference work covering more than 10 million installed horsepower of compressor installations. Revenue figures, headcount, and ownership structure are not publicly disclosed.

Broad incumbents

• KBR: KBR is a global engineering, procurement, and construction services firm with significant oil & gas, petrochemical, and government services exposure. Comparable to EDI as an industrial engineering services buyer of vibration and reliability expertise.
• Wood Group (John Wood Group): Wood is a large engineering and consulting firm serving oil & gas, power, and process industries with reliability, rotordynamics, and asset integrity services. EDI competes with Wood's specialized vibration and machinery consultants for the same industrial accounts.
• SKF Reliability Systems: SKF provides rotating-equipment monitoring, condition-based maintenance, and reliability services including vibration analysis and bearing condition assessment. Overlaps with EDI's reliability and vibration diagnostic offerings for industrial customers.
• Brüel & Kjær (HBK): HBK (formerly Brüel & Kjær) provides sound, vibration, and acoustic measurement instrumentation and software used in industrial and research settings. Comparable to EDI's instrumentation layer and acoustic/pulsation analysis capabilities.
• IRD Balancing (Roper Technologies): IRD, part of Roper's technology portfolio, supplies rotating-equipment balancing, condition monitoring, and vibration analysis products and services. Competes with EDI for industrial reliability budgets, particularly in power generation and process industries.
• Bently Nevada (Baker Hughes): Bently Nevada, now part of Baker Hughes, is the dominant supplier of rotating-equipment monitoring instrumentation and condition-monitoring software (System 1). EDI uses complementary instrumentation and competes for the same reliability-engineering budget, though Bently Nevada sells products plus embedded services.
• Computational Systems, Inc. (CSI / Emerson): CSI, part of Emerson's reliability solutions, supplies vibration analyzers, online monitoring systems, and predictive diagnostics software. Overlaps with EDI in target customers and reliability use cases, though CSI is product-led rather than services-led.

Direct peers

• Mechanical Dynamics & Analysis (MD&A): MD&A provides vibration analysis, rotordynamics, and field balancing services for power generation, oil & gas, and industrial clients. It is the closest direct competitor to EDI's vibration and pulsation consulting practice, with similar API-driven methodology and customer base.
• Structural Integrity Associates (SI): SI delivers structural, mechanical, and reliability engineering services including vibration, fatigue, and fracture-mechanics analysis for power, oil & gas, and aerospace clients. Comparable to EDI in its emphasis on failure-prevention consulting and standards-driven analytical work.
• Azima DLI: Azima DLI provides vibration monitoring, condition monitoring, and remote diagnostics services to industrial customers. Directly comparable to EDI's field-testing and diagnostics offering, with a similar reliance on proprietary analytics and expert interpretation.
