Selected Projects
Our Experience in Practice
Explore examples of ACC's corrosion investigations, cathodic protection installations, specialist testing and ongoing monitoring across Australia.
Cathodic Protection Replacement
Barkly Square, Brunswick. ACC replaced the ageing cathodic protection system protecting the building’s foundations, with new anodes and rectifier equipment and specialist drilling support.
Corrosion Investigation & Cathodic Protection
Boyer Paper Mill, Tasmania. ACC investigated water-main corrosion, then designed, installed and commissioned an impressed current cathodic protection system and provided corrosion training for mill staff.
Fuel Infrastructure CP Monitoring
BP aviation fuel installations. ACC monitored cathodic protection for buried steel fuel tanks at airport sites across Victoria and NSW. Chartered aircraft helped the team reach dispersed locations.
Pipeline Coating & CP Surveys
BP wharf pipelines. DCVG and CIPS surveys at Burnie, Gladstone and Mackay assessed coating defects and cathodic protection performance, identifying locations where further wall-thickness testing would be useful.
Structural Steel Corrosion Mitigation
Majestic Building, St Kilda. ACC designed a hybrid cathodic protection system for embedded structural steel and supervised specialist installation as part of the building’s façade remediation.
Stray Current Investigation
NMIT Epping campus. ACC investigated premature copper water-pipe failures, identified rail-related stray current with Energy Safe Victoria, and developed a drainage-system design with nearby asset owners.
Independent Corrosion Engineering Expertise
Established in 1987, Australasian Corrosion Consultants is a specialist corrosion engineering consultancy providing investigation, cathodic protection and corrosion monitoring services across Australia.
Our multidisciplinary team combines engineering analysis with practical site experience to develop solutions suited to the asset, operating environment and client requirements. We work with asset owners, consulting engineers and contractors to support corrosion investigations, infrastructure projects and the ongoing management of existing cathodic protection systems.
Frequently Asked Questions
What does a corrosion assessment involve?
An assessment investigates the condition of an asset and the causes of corrosion. Depending on the structure and concern, ACC may use visual inspections, electrochemical measurements or material testing. We explain the findings in a report and recommend practical options for protection, repair or ongoing maintenance.
Can you investigate concrete cracking, spalling or reinforcement corrosion?
Yes. ACC investigates corrosion and deterioration in reinforced concrete structures. We use inspections and targeted testing to assess the cause and extent of the problem, then provide a condition report with recommendations for repair, remediation and maintenance.
Can you design and install a new cathodic protection system?
Yes. ACC designs, supplies, installs and commissions impressed current and sacrificial anode cathodic protection systems. The appropriate approach depends on the asset, its environment and its condition.
Can nearby rail systems cause corrosion in buried assets?
Stray electrical currents from DC rail systems can contribute to corrosion in nearby buried metal assets. ACC investigates this interference through baseline testing, monitoring and reporting, and provides advice on mitigation. Other potential sources include welding equipment and nearby cathodic protection systems.
What types of assets and industries do you work with?
ACC works with pipelines, storage tanks, reservoirs, marine structures and reinforced concrete infrastructure. Our clients include utilities, asset owners and project teams in water, energy, oil and gas, marine, construction, mining and transport.
Do you provide corrosion consulting across Australia?
Yes. ACC supports projects across Australia, including corrosion investigations, cathodic protection and ongoing monitoring. Tell us where your asset is located and what assistance you need so we can discuss a suitable scope of work.
How do I know if an existing cathodic protection system is working correctly?
ACC assesses existing cathodic protection systems through routine and annual surveys, performance assessments and fault-finding. Depending on the asset and system, testing can include instant-off potential measurements, depolarisation testing, rectifier output and checks of electrical connections. We compare results with the applicable protection criteria, standards and project specifications, then recommend maintenance, repairs or upgrades where needed.
Can ACC investigate corrosion problems without installing cathodic protection?
Yes. ACC investigates why corrosion is occurring and recommends measures suited to the asset and its environment. An investigation may lead to advice on repairs, coatings, material selection or ongoing management. Installing a new cathodic protection system is only one possible response.
