AEC & ACA VIC Branch – CP Seminar – The May Corrosion Spectacular

The Australian Electrolysis Committee and Victorian Branch of the ACA are pleased to host a joint meeting all about Cathodic Protection – The May Corrosion Spectacular! This webinar, which took the place of the annual electrolysis committee meeting and include the AGM, featured a diverse range of presentations covering CP rectifiers, data monitoring and much more.

Copper Based Antifoulings on Aluminium Marine Vessels

Antifouling coatings for aluminium vessels have been a controversial subject for many years and for many years the use of organo-tin based coatings was seen as the most effective long term option. Organo-tin products are no longer an option and this has resulted in evaluation of alternatives. Traditionally the use of copper based products (Cuprous Oxide mostly) had been an effective option for steel hulls but were avoided for aluminium due to concerns with the interaction between the Cuprous Oxide and aluminium hull.

Preparation for Windtower Coating Using a Bristleblaster

The ACA hosted a presentation and product demonstration from Phil Chester, Managing Director of Montipower. In this webinar, Phil presents some case studies covering recent and ongoing projects where the Bristle Blaster is being used specifically for wind tower repairs. This presentation included a demonstration of the correct use of the tool and an explanation of the difference between the Bristle Blaster and an often confused tool in the market. Whilst Phil primarily discusses wind tower maintenance, the principle of preparation for coating a wind tower is virtually the same as any steel preparation when it comes to using the Bristle Blaster.

Using Stainless Steel in a Marine Environment

Graham’s lecture focusses on the selection and use of stainless steel in seawater (especially in piping), the importance of correct procedures and practices in fabrication and the usefulness of Copper Nickel alloys.

Managing Corrosion Using Integrity Operating Windows

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.

Conservation of Cultural Heritage

Our island nations are littered with historic shipwrecks which have been recording the microenvironment of the oceans since 1622 off the Western Australian coast. A study of the layers of decay recorded on degraded metal objects provides climate and corrosion scientists with a unique insight into the changing conditions on the seabed and with data on seawater temperatures.

Working Through COVID 19 For the Corrosion Industry

The COVID-19 global health crisis has impacted all our lives to an extent not experienced this century. Our personal, family, social and vocational lives are all going through unprecedented change and the need for all of us to adapt and innovate has been forced upon us by one of the most significant market disruptions many of us have ever faced. While many of the challenges we face are universal, every industry, organisation and business is unique and the complications and opportunities that have arisen are varied. To explore how this crisis is affecting those within the corrosion mitigation industry, the ACA hosted an interactive webinar panel featuring a selection of guests speakers from different industry subsets representing Contractors, Asset Owners, Consultants, Coating Suppliers and Equipment Suppliers.
