Cathodic Protection Monitoring for Buried Fuel Tanks
ACC provides annual cathodic protection performance reviews for buried aviation fuel storage tanks protected by sacrificial anode cathodic protection systems. For remotely located sites, ACC assesses remotely collected monitoring data to evaluate protection levels, confirm system performance against recognised criteria and review long-term potential trends.

Barkly Square Cathodic Protection
ACC replaced the original cathodic protection system protecting the foundations of Barkly Square Shopping Centre. The system, installed in 1985, had consumed its anodes and required an upgrade. Four new horizontal anodes were installed between the foundation piles, and the two existing rectifier units were replaced with higher-capacity equipment. R&R McClures Excavations carried out horizontal drilling beneath the building, with technical supervision and support from ACC. Steel sleeves housed the anodes, which were installed using a custom mechanism developed by ACC.

Boyer Paper Mill Water Main
Following a water-main failure that caused a 24-hour shutdown in December 2008, ACC investigated corrosion at Norske Skog’s Boyer Paper Mill. The investigation identified a highly corrosive environment and numerous coating defects along the pipeline. ACC developed an impressed current cathodic protection design in 2012, then installed and commissioned the system for the water main between the mill and Pulpit Road. The project also included corrosion training for mill staff, covering corrosion mechanisms and asset protection.

Fuel Infrastructure CP Monitoring
ACC carried out annual cathodic protection monitoring of buried steel aviation-fuel tanks at airport sites across Victoria and New South Wales. The monitoring program covered 17 dispersed locations. A chartered aircraft allowed ACC to reach the sites efficiently and carry out the surveys without extensive travel by road. This project demonstrates ACC’s experience coordinating field monitoring across multiple fuel installations and assessing the protection of buried steel tanks.

BP Wharf Pipeline Surveys
As part of BP Australia’s pipeline baseline program, ACC carried out Direct Current Voltage Gradient (DCVG) and Close Interval Potential Surveys (CIPS) on wharf pipelines at Burnie, Gladstone and Mackay. The surveys assessed coating defects and the protection provided by the existing cathodic protection systems. ACC identified locations where ultrasonic wall-thickness testing would be most useful and provided recommendations to support pipeline integrity and maintenance planning. This work supported BP’s wider Pipeline Integrity Management System.

Majestic Building Façade Remediation
Corrosion of steel columns embedded in mortar and brickwork had caused cracking and deterioration in the Majestic Building’s façade on Fitzroy Street, St Kilda. ACC developed a cathodic protection solution as part of the remediation works and supervised the installation of a hybrid system. Grout around the steel columns provided a suitable medium for the anodes, which combined sacrificial protection with an initial impressed current phase. Specialist abseilers installed the anodes within the façade under ACC’s supervision.

NMIT Stray Traction Corrosion
ACC investigated accelerated failures in the copper water-pipe network at NMIT’s Epping campus. Working with Energy Safe Victoria, ACC identified that the adjacent rail network was changing pipework potentials and contributing to stray traction corrosion. The work involved testing and continuity bonding assessments, followed by the design of a suitable drainage system in collaboration with nearby asset owners. The project demonstrates the coordinated investigation and engineering response required when electrical interference affects buried infrastructure.

23ML Water Storage Tank Protection
ACC designed, supplied, installed and commissioned a new impressed current cathodic protection system for two 23 megalitre water storage tanks.

Rotary Park Wet Well Assessment
ACC carried out detailed condition assessments of the sewage wet well at Rotary Park, Gisborne, in 2010 and 2020. The inspections assessed deterioration and helped identify repair needs and remaining service-life considerations. Visible concrete defects were classified and quantified, followed by diagnostic testing and sampling of the concrete and its environment. Access to the enclosed wet well required specialist confined-space procedures, including cleaning, ventilation, gas monitoring and controlled entry. The work provided condition information to support the asset owner’s maintenance and remediation planning.
