Webinar – Galvanic Corrosion in Water and Wastewater Structures

ACA delivers Corrosion Under Insulation course

The ACA is launching a course that introduces the theoretical and practical aspects of preventing, managing and inspecting corrosion under insulation (CUI).

Understanding Natural Biofilm Development In Marine Environments‚ A Review

Surface colonisation by microorganisms is a ubiquitous process in the marine environment. The formation of a mature biofilm structure, which is described as an aggregate of attached cells surrounded by extracellular polymeric substances (EPS) is the final stage of colonisation. In this form, bacteria, fungi and archaea have been implicated in several deleterious effects on...

A Novel Approach to Shallow Water Corrosion Modelling

Use of Shipwreck Material From HMS Sirius (1790) The ability to obtain accurate measurements of corrosion rates in shallow water sites is generally limited, owing to extreme operational conditions for test rigs, the cost of experimental setups and limited time exposure of a few years. Museum conservators have authorised access to a wide range of...

MILES of PILES: A Symposium on the Care and Maintenance of Marine Piles

The marine environment is one of the harshest settings in terms of causing the corrosion of metal structures and components. The webinar organised by the Victorian Branch of the Australasian Corrosion Association focuses on marine coatings and technology to minimise problems caused by the corrosion of marine structures. We heard from three leading industry experts, Peter Dove (GHD), Kyle Fortune (Denso) and David Anderson (UCC) on issues and recent advances in this important area.

Maritime Event | Roundup

The technical program included speakers from: Dulux, Marine and Civil Maintenance, AECOM, Fibrecon, V-Rod, ASC Shipbuilding, Jotun Marine and the ACA. Special thanks as always to our sponsor for the event – Dulux Protective Coatings – without whose support the event wouldn’t have been the success it was. We were especially pleased to welcome and...

Maritime Event in Cairns

There are a few place left on this event  on the 20th November This one-day seminar takes a look at corrosion mitigation systems and different management strategies for marine infrastructure.  This event is for anyone who has involvement with managing corrosion in marine environments. Engineers Asset owners Maintenance managers Designers Managers Ship builders Contractors The...

Anti-fouling Innovation | Keeping ships at sea longer

Dr Andrew Ang of Swinburne University of Technology (Melbourne, Australia) has been selected overall winner for the prestigious 2018 Fresh Science Victoria Award for work related to corrosion and biofouling,  A new corrosion-resistant coating that halved the build-up of algae and barnacles on ship hydraulic components is now being trialled on HMAS Canberra, one of...

Anodes, Chemical Composition & Your Boat

Let us start by saying that there is nothing mystical about anodes. They sacrifice themselves to protect your hull and other immersed or buried metallic fittings against corrosion. Metals and Alloys that are higher on the Galvanic Table protect those alloys below them. The  Galvanic Series in Seawater table Decades of research and field testing...

STRUCTURAL CORROSION ISSUES ON COLLINS CLASS SUBMARINES | 2006

Author: Mr. Roman Dankiw Senior Technical Officer Directorate of Submarine Engineering Structural & Naval Architecture Group This paper is a modified summary from a study conducted by the Submarine Branch to identify and quantify the impact of corrosion on the Collins Class platforms during major maintenance activities. The results of the study led to prioritising...

Pure Polyurea, Corrosion Protection & Offshore Oil Rigs

Pure Polyurea, Corrosion Protection & Offshore Oil Rigs Rhino Linings Australasia Pty Ltd (RLA). Both abrasive and corrosive, the marine environment is unforgiving of maritime structures such as offshore platforms, rigs, and ocean-going vessels—all of which are major investments for the companies operating them. All activities in a marine environment are impacted by corrosion; the...

Corrosion Challenges Report

In 2010 the ACA produced a report on the impact of failure of infrastructure assets through corrosion as a result of current practices and skilling in the Australian mainland urban water and Naval defence sectors. The objective of this project is to examine, identify and estimate corrosion failure costs attributable to industry practices, industry skilling and regulatory frameworks, and estimate potential corrosion failure cost reductions by implementing avoidable/preventable strategies.

Subsea Pipeline Corrosion Management

At offshore oil and gas fields around the world, there are thousands of kilometres of subsea pipelines connecting drilling rigs and production platforms to wellheads and onshore facilities. These represent billions of dollars of investment by companies over many years. Owners of these high-value assets must understand the cost implications of ignoring the effects of...
