Electronic Corrosion Engineer v5.8(ECE)

Used by operators and engineering contractors worldwide, ECE™ delivers realistic corrosion assessments calibrated to real field data.

Corrosion caused by the process fluids is one of the main challenges in the design and operation of facilities for oil and gas production, pipelines, process facilities and other systems. ECE® is a tool that assists corrosion engineers through the quantitative estimation of corrosion rates and selection of corrosion-resistant materials. At the heart of ECE is a model for corrosion analysis, firmly based on laboratory data and on-field calibration studies with pipelines, piping and downhole tubing.

ECE is relied on by operators, engineering contractors and suppliers worldwide to support critical decision-making, for example:

• New project feasibility and concept studies

• Front–end and detailed design engineering

• Selection of suitable and cost-effective materials

• Analysing operational corrosion problems

• Life-prediction and life-extension

ECE is applicable where corrosion is primarily due to acid gases (carbon dioxide and hydrogen sulphide), for example, in front-end oil and gas production, pipelines, downstream processing, as well as in geothermal energy and some situations in power generation, refining and other industries.

Key features

• Corrosion rate estimation for steel downhole tubing, flowlines pipelines, and process piping

• Selection of corrosion-resistant alloys considering corrosion, pitting and stress-corrosion cracking

• Multiple point calculation along well tubing string or along a pipeline/flowline

• Multi-stream bulk calculation function with spreadsheet import and export capability

• Treatment of sweet (CO₂ ) and sour (CO₂ + H₂S) service conditions

• Corrosion evaluation incorporates critical factors such as oil API gravity, water-cut, flow rates, tubing deviation angles, carbonate and sulphide scaling, flow regime, top-of-line corrosion

• Lifecycle cost analysis

• Supplier reference list

• Extensive technical help files

• User-friendly reporting, printing and saving of outputs and data files

• Fully supported product with IT and engineering support and with regular updates for licencees

ECE 5.8 – 2023 updates now available

• Monte Carlo probabilistic modelling – a powerful new time-saving tool for use in sensitivity studies performed at the design stage or when modelling the variability of field data used in operational studies

• Any input variable to the ECE flowline corrosion predictor may now be defined as a probability distribution, rather than a single discrete value

• Probability distribution is defined simply using the minimum and maximum possible values expected in the range

• Supports distribution types within the calculation: uniform, normal, triangle, and LogNormal

• Performs up to 100,000 Monte Carlo calculations for each simulation

• Predicts the corrosion rates expected for the 25th, 50th, 75th, 90th, 95th, and 99th percentiles

• Provides bulk import Monte Carlo calculation support for up to 1000 streams

• Provides full reporting functionality

• Provides more user feedback when entering invalid data during bulk imports

• Allows the user to apply the inhibitor factor to the pitting rate in corrosion calculations

• Adds Sheer Stress as outputs to both Standard Flowline and Monte Carlo Calculation Bulk export results
