From Wikipedia, the free encyclopedia


Tetra Engineering Group Inc. is a private engineering consulting firm specializing in services for the power generation industry, with a particular focus on Heat Recovery Steam Generators (HRSGs) and steam cycle systems. Founded in 1988, the company is headquartered in Weatogue, Connecticut, United States, and operates additional offices in Valbonne, France, and Dubai, United Arab Emirates. Tetra Engineering provides a range of services including inspections, failure analysis, performance assessments, and engineering support for power plants worldwide.

History

[edit]

Tetra Engineering was established in 1988 by three engineers who previously worked together at a major nuclear and fossil boiler Original Equipment Manufacturer (OEM) in the United States. The company initially focused on improving the performance and reliability of nuclear and large fossil-fired power plants. In the late 1990s, Tetra Engineering expanded its services to address the growing installed base of HRSGs, reflecting the increasing complexity of these systems in power plants. Over time, the company further developed its expertise to include life-cycle management, root-cause analysis, and system design optimization. A European office was opened near Nice, France in 1991 and an office in the UAE in 2014.[1]

Locations

[edit]

With offices in the United States, France, and the United Arab Emirates, Tetra Engineering serves clients in more than 50 countries. The company’s international footprint enables it to provide localized support and expertise to a diverse clientele in the power and process industries. As of 2024, Tetra Engineering has offices in 2 countries.

[edit]

Tetra Engineering offers a comprehensive suite of engineering consulting services tailored to the needs of power generation and steam process plants:

    • HRSG and Boiler Inspections: Conducting thorough inspections to assess the condition and performance of steam generation assets. [2][3]
    • Power Piping Services: Providing examination and field testing to ensure the safe and reliable operation of power piping systems.
    • Decarbonization and Renewable Services: Combining expertise in steam cycles with evolving renewable technologies, including hydrogen and concentrated solar power plants.  
    • Engineering Support Services: Offering support for legal disputes, third-party engineering assessments, and quality audits.
    • Life and Integrity Assessments: Determining the root causes of failures, evaluating plant performance and efficiency, and assisting in maintenance planning to ensure the longevity of generating assets.  
    • Software Solutions: Providing advanced piping management software packages, such as PipeVue 2.0, for tracking compliance with ASME B31.1 reporting requirements.   Tetra Engineering has provided HRSG-related services for over 700 units globally, supporting clients in maintaining and improving the reliability and performance of their power plants.

Industry Contributions

[edit]

The company is noted for publishing research and technical guides on topics like HRSG tube failure statistics and corrosion assessments. These contributions have been widely referenced in industry publications, including Power Magazine.

Certifications

[edit]

Tetra Engineering Group, Inc. was awarded the "R" Stamp for Design for Alterations by the National Board of Boiler and Pressure Vessel Inspectors (NBIC). This certification authorises the holder to develop and implement modifications to Heat Recovery Steam Generators (HRSGs), boilers, and pressure vessels designed to ASME Boiler & Pressure Vessel Code Sections I and VIII.
