This Event Will Now Be Run as an Online Webinar.

The Victorian Branch AGM will now be held on the 15th of April 2020 and will mark the ACA’s first Online event.


During this section of the meeting, Candice Blackney will deliver the Presidents report, elections for the 2020 Victorian Branch Committee will take place and the floor will be open for any member questions and discussions.

The Presidents Report will be available for circulation in Branch emails.

6PM – 6:45PM

The second half of the night is a technical event ‘Hidden defects and defective process control’. We are fortunate to have Peter Wilson from Nuffield group presenting his topic related to defects and management of infrastructure. Now that we are all under lockdown, Peter has kindly agreed to present our first technical webinar. Subsequently, this event will be open to all, so feel free to register regardless of your branch.

Eliminating defective process control as a cause of corrosion



Unexpected corrosion damage is just as likely to arise from defective process control & lack of recognition of potential damage mechanisms, as incorrect alloy selection.

Operating plant is subject to variability of service condition arising from changes in feedstock, temporary process upsets, shutdowns for inspection and restart all representing a significant challenge to reliable operation.  Corrosion damage mechanisms may proceed intermittently or steadily and time to failure may range from seconds to years and consist of initiation and propagation phases.

A management practice for avoiding defective process control will be described which requires identification of integrity operating windows (IOW) that define rates of damage propagation:

  • target windows for safe and reliable long-term operation;
  • standard windows for a known but manageable rate of damage propagation;
  • critical windows: operating outside this critical window will lead to rapid failure of equipment.

Examples from hydrocarbon gas processing will be used to illustrate the IOW management practice which includes defining responses to excursions at each IOW, revealed by instruments and sensors which monitor and control the process.
