Analysis is Essential

Power and process plant equipment over time inevitably is subject to failures and deterioration with attendant loss of performance.  Understanding and predicting these events and phenomena requires experience, obtained through an extensive background in field inspections and in applying the appropriate desktop tools such as Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD) and thermohydraulic process simulation.  Tetra Engineering provides a full scope of analytical services to help you assess what has happened or predict what will happen to your power plant components.

Our Life & Integrity Assessment Services

We can tailor our services to your needs

Finite Element Analysis (FEA)

Finite Element Analysis (FEA)

Finite Element Analysis (FEA) provides advanced analysis on HRSG components to determine the effects of fatigue, thermal stress and other associated occurrences and prevent losses in efficiency and/or failures.

Fitness for Service

Fitness for Service

A fitness for service (FFS) evaluation is a process for assessing the structural integrity and safety of components that may have experienced damage and deterioration during their service life.

Boiler Process Modelling and Simulation

Boiler Process Modelling and Simulation

Tetra Engineering provides a full-scope service for the modelling and operation analysis of all types of natural or forced circulation Power Boiler and HRSGs, including supercritical and once-through designs. This can be integrated into a full plant model to incorporate the steam turbine and steam cycle balance of plant.

Flow Accelerated Corrosion Assessment (FAC)

Flow Accelerated Corrosion Assessment (FAC)

Identify and prevent tube and pipe thinning caused by flow-accelerated corrosion (FAC) to avoid ruptures and leaks.

Optimized NDE

Optimized NDE

Risk-based inspection (RBI) is an approach for ranking the priority of inspection and maintenance according to an assessed risk to the component or system integrity. One key aspect of any RBI program is to carefully select the locations for non-destructive examination (NDE) that are most susceptible to damage, according to the component's design and past and project operating mode, while considering the resources and time available during an upcoming inspection. Using multi-disciplinary experience and tools (thermal simulation, life assessment, structural calculations….) Tetra will help you get the most out of your NDE campaigns, by providing pre-outage planning, on-site supervision and post-inspection review.

Root Cause of Failure (RCA)

Root Cause of Failure (RCA)

Knowing the fundamental causes leading to failure is essential to mitigate the risk of the failure repeating. Tetra Engineering calls on an interdisciplinary team to assess the failure (or degradation) and determine the root cause.

Performance & Efficiency Assessments

Performance & Efficiency Assessments

Services to help you evaluate how your operating performance has changed since the plant / boiler was commissioning, or to help you check the potential performance impact of planned modifications before they are implemented.

Grade 91 Low Alloy Steel Concerns for Older CCGTs

Grade 91 is a CSEF (creep strength enhanced ferritic) alloy introduced in the late 20th century for high temperature service in power boilers. ASME BPVC-II develops material properties based on time-to-rupture data after 100,000 hrs, with a safety factor of 3.5.
