Technical Engineering Consultants

What Technical Engineering Consultants does

Technical Engineering Consultants, LLC (TEC) is a privately-held, multi-discipline engineering consulting firm headquartered in Gretna, Louisiana, that has served the oil and gas, marine, and petrochemical industries since 1984. The firm was founded by two structural engineers who designed offshore platforms for independent Gulf of Mexico producers and has since grown into a five-discipline practice covering mechanical and pipeline engineering, process engineering, civil and structural engineering, electrical and instrumentation engineering, and project management. TEC has designed more than 450 offshore structures worldwide, ranging from shallow-water single-well caissons to deepwater multi-pile platforms, and has delivered projects in 25+ countries through direct enterprise sales to oil and gas majors and independents.

The firm's technical capabilities rest on industry-standard engineering software rather than proprietary technology: advanced 3D CAD with point cloud processing for survey and modeling, Caesar II for pipe stress analysis, HYSYS for process simulation (gas dehydration, separation, compression, flaring), and PLC/DCS/SCADA systems for electrical, instrumentation, and control system design. Services span the full project lifecycle from conceptual design and feasibility through detailed engineering, procurement support, construction management, and start-up and commissioning. The company maintains in-house capabilities across all five disciplines, allowing it to execute both greenfield and brownfield projects domestically and internationally without reliance on sub-consultants for core technical functions.

TEC operates as a traditional professional services firm with project-specific, custom-quoted pricing and multi-year contract cadences. The client roster reads as a who's-who of upstream and midstream oil and gas, including BP, Chevron U.S.A., Shell Offshore, Marathon Oil, Devon Energy, Apache, Petronas, ENI, and Woodside, alongside numerous independent Gulf of Mexico producers. Marketing is minimal — primarily the company website showcasing portfolio and capabilities — and the firm relies on direct relationship-based enterprise sales. TEC is bootstrapped with no external funding, no parent company, and no disclosed institutional ownership; it is described as a family business at heart with multi-decade staff tenure, consistent with a founder/owner-operated consultancy that has grown organically across nearly four decades.

Broad incumbents

• TechnipFMC: Global leader in subsea, offshore, and surface engineering for the energy industry, including offshore platform design and process engineering. Highly comparable to TEC in offshore structural and process engineering for oil and gas, but at substantially larger scale.
• Burns & McDonnell: Major multi-discipline engineering firm providing process, mechanical, electrical, civil/structural, and project management services to oil & gas, chemicals, and power clients. Overlaps with TEC's full service mix, but at much larger scale and with broader industry coverage.
• Worley Limited: Global engineering and professional services firm providing multi-discipline engineering across energy, chemicals, and resources. Comparable to TEC in the oil & gas and petrochemical engineering services domain, but operating at vastly greater scale with thousands of engineers and full EPC delivery capability.
• Wood Group (Wood plc): Global engineering and consulting firm with deep oil & gas, process, and offshore engineering capabilities, including offshore structural design. Overlaps with TEC on multi-discipline engineering services for oil and gas and petrochemical clients, but at much larger scale.
• KBR (Kellogg Brown & Root): Global engineering and government services firm with significant oil & gas, petrochemical, and offshore engineering capabilities. Directly comparable service lines to TEC's five core disciplines, but operates globally with EPC scale and government services portfolio.
