Corrosion model with real-world calibration
ECE® provides realistic corrosion modelling assessments calibrated to actual field data for operators and engineering contractors globally.
Corrosion caused by CO2, H2S and O2 in process fluids is one of the main challenges in the design and operation of facilities for oil and gas production, pipelines, processing and other systems.
ECE helps engineers and operators predict corrosion rates and select corrosion-resistant materials using a combination of lab data and real-world field calibration studies on pipelines, piping and downhole tubing.
Corrosion analysis
Operators, engineers, contractors and suppliers worldwide rely on ECE to support critical decision-making related to corrosion management. ECE can be used to:
- Conduct feasibility and concept studies for new projects
- Perform front-end and detailed design engineering
- Select cost-effective and suitable materials
- Analyse operational corrosion issues
- Predict and extend asset life
ECE is applicable where corrosion is primarily caused by acid gases such as CO2 and H2S.
This includes front-end oil and gas production, pipelines, downstream processing, geothermal energy and, in some situations, power generation, refining and other industries.
ECE features
Corrosion
prediction
Analyse potential corrosion rates of carbon steel flowlines and tubing with presence of O2, CO2 and H2S.
CRA (corrosion resistant alloy) evaluation
Select suitable materials by assessing resistance to corrosion considering factors like service conditions, alloy types and long-term cost analysis.
Both ISO 15156-3 sour service and ECE’s own rules are available to assess future conditions.
Lifecycle cost
calculation (LCC)
Evaluate the lifecycle cost of CRA compared to carbon steel, considering OPEX and CAPEX requirements.
CO2 transport
systems
Qualitatively assess corrosion by using thermodynamic simulations to predict free water content for dense phase or supercritical CO2 systems.
Monte Carlo
probabilistic modelling
Gain confidence in predictions and save time with sensitivity studies performed at the design stage or when modelling the variability of field data used in operational studies.
Run multiple simulations with varying parameters for an extensiveanalysis of potential outcomes, resulting in more accurate corrosion predictions.
How it works
Bottom of line, top of line and pitting corrosion rates for carbon steel are modelled in flowline and tubing systems based upon the concentrations of CO2 and H2S, the water chemistry and the flow conditions.
The model considers the potential benefits of protective scales, liquid hydrocarbons, glycol injection and corrosion inhibition.
The oxygen corrosion model considers the temperature, salinity, flow rate and dissolved oxygen concentration in water injection systems to predict a general corrosion rate due to the presence of oxygen. The model can also be used to predict oxygen decay due to corrosion along the length of a pipeline.
Monte Carlo analysis is supported within the flowline CO2 and H2S corrosion predictor tool. This allows detailed sensitivity analysis to be performed using the Monte Carlo technique allowing the variability of key input data to be considered.
Normal, Uniform, Triangular and Log Normal distributions are supported for up to 100,000 iterations with percentile results provided at P25, P50, P75, P90, P95 and P99 levels.
The CRA evaluator assesses the suitability of different alloys in production environments by analysing the temperature, partial pressure of CO2 and H2S, pH and chloride.
The evaluator uses ECE's own rules and the ISO15156-3 sour service standard to identify suitable alloys for the operating conditions.
The ECE lifecycle calculator uses the net present value technique to evaluate the total cost for CS vs CRA flowline and tubing options considering the varying OPEX and CAPEX costs of both materials.
Excel interfacing for point calculations is supported for the flowline corrosion predictor, the flowline CRA evaluator and the tubing CRA evaluator for the calculation of up to 1000 results at a time.
Flowline sectional data may also be imported from Excel and all calculated data points within ECE can be exported to Excel for external analysis.
Detailed simulation reports documenting all inputs used in a simulation and the corresponding results can be exported to Word, Excel and PDF formats.

Common questions
ECE (Electronic Corrosion Engineer) is a software tool designed to assist corrosion engineers in estimating corrosion rates and selecting corrosion-resistant materials. It uses a model based on laboratory data and field calibration studies.
ECE is used by operators, engineering contractors, and suppliers worldwide to support critical decision-making in new project feasibility, design engineering, material selection, and operational corrosion problem analysis.
ECE is applicable in industries where corrosion is primarily due to acid gases like carbon dioxide and hydrogen sulphide. This includes oil and gas production, pipelines, downstream processing, geothermal energy, power generation and refining.

The latest version of ECE is 6.0, is available as both a web and desktop solution. The web version provides access from anywhere with automatic updates and no setup required, while the desktop version supports offline use, managed updates, and takes advantage of local processing power. Both are built on trusted, industry‑standard corrosion models and have been relied upon by corrosion engineers for over 25 years.
We offer webinars and other resources to help users understand and effectively use ECE.
