ECE® version 5.3 is released!

New or significantly revised features in version 5.3 include:

  • Improved installation procedure.  Upgrade quicker and easier than ever!

  • Enhanced Help File – Now more user friendly!

    • Hyper-linked index page for quick access to subject matter.

    • Launch from within ECE® and viewable side by side.  No having to jump between windows.

    • Context sensitive topics can be accessed directly from ECE®.

    • Fully Printable.

  • Improved Corrosion Predictor Reports

    • Summary & Full Report options

    • Chloride & Corrosion Pitting rating now reported.

  • 6Mo super-austenitic stainless steel added to Flowlines Alloy Evaluator.  View the suitability of this material based on ECE® and ISO 15156-3 rules.

  • Increased Chloride range in the CRA Evaluator tools.

  • H2S can now be entered in ‘ppm’ making it much simpler to input smaller H2S levels.

  • Improved usability of input ranges.  ECE® responds more intuitively to values entered outside of selected ranges.

  • Increased number of calculation points depending on flowline length gives greater precision for pipelines above 1 km length.

  • Acetic Acid input is available in CRA selection tools for a more accurate pH calculation.

  • Corrosion rate graph now available in ‘mil per year’ version.

  • An exciting new Bulk Calculation function in the Flowlines module. 

    • Save time by uploading calculations for multiple streams via a validated spreadsheet.

    • Export results straight back to spreadsheet format.

  • The allowable range of values of C value for calculating Erosional Velocity as per API RP 14E has been extended.


Wood Group Intetech’s ECE® program is a tool for the quantitative estimation of corrosion rates and the selection of materials for oil and gas production systems and processing facilities. At the heart of ECE-5 is a new and improved model for corrosion analysis and material selection, firmly based on laboratory data, and field calibration studies both with pipeline and with downhole tubing.

The software is available as a stand-alone PC version for single users or a server-based system for multiple users.


ECE® 5 is fully supported. Licensees receive regular updates, including further functionality improvements and new materials data, and have the benefit of expert technical support.

Invaluable tools

  • Corrosion rate predictor for carbon steel in sweet and sour conditions that considers different options for corrosion control
  • Risk prediction tools that evaluate the risk of carbon steel failure
  • Corrosion-resistant alloy evaluators that select the most suitable alloys for the specified environmental conditions and automatically take into account the risks of corrosion, pitting and stress-corrosion cracking
  • Life cycle cost calculators that evaluate the economics of carbon steel and corrosion-resistant-alloys option based on net present value, so that material cost comparisons can be made
  • An alloy-tubing and pipe manufacturer database

Key features

  • Corrosion-rate prediction for sweet and sour service conditions based on the fundamental chemistry of the solubility of the corrosion products
  • Corrosion evaluation incorporates critical factors such as oil API gravity, water cut, flow rates and angle of flow
  • Calculated outputs for multiple positions along a flowline or up a tubing string
  • Instant output updates, for example, corrosion-rate profiles, with changes in input parameters
  • Carbon steel failure risk evaluation considering both generalised and pitting corrosion risks
  • Quantitative evaluation of corrosion-resistant-alloy suitability for a matrix of conditions that covers temperature, partial pressure of carbon dioxide and hydrogen sulphide, chloride content and pH
  • Life cycle cost analysis that takes into account fabrication speed, pipe-laying method and means of corrosion control
  • Help files with technical background and references
