Owners and operators of high-value assets need to understand the cost implications of ignoring the effects of corrosion that poses a threat to all infrastructure through the degradation of structures such as buildings, roads, bridges, pipelines and towers. The economic impact of corrosion represents an annual cost of many billions of dollars to the economy....

Monitoring the impact of corrosion on subsea pipelines and offshore structures is a critical aspect of ensuring pipeline integrity. A key way of minimising corrosion is to employ the most appropriate technologies and prevention techniques. Owners of high-value infrastructure assets such as pipelines and production platforms must understand the cost implications of ignoring the effects...

As the global economy continues to grow the markets for petroleum products continue to expand. To meet increasing demand, more and more oil and gas infrastructure is being built. Corrosion poses a threat to all infrastructure and the economic impact of all types of corrosion and it’s degradation of infrastructure, such as pipelines, oil rigs...

To ensure that there is no danger of a pipeline rupturing, most countries require regular inspections of any company operating both onshore and offshore fields and they must be able to certify compliance. One method of monitoring a pipeline’s CP system in the case of offshore pipelines is called Electrode Field Gradient (EFG) measurement where...

Another aspect that makes the interface difficult is that the crossing is often through an environmentally sensitive area. For example, on Australia’s North West coast, the shore crossing for one offshore field is on Barrow Island, where there are strictly enforced quarantine restrictions. The requirement to strip down all equipment and vehicles for cleaning prior...
28th February 2017One corrosion control method used on pipelines is cathodic protection (CP). This is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded “sacrificial metal” to act as the...
28th February 2017“Historically, pipelines were designed for 20 to 25 years, following which time they underwent a ‘life extension’,” he said. “These days the design life is set at 50 years for some projects.” DWA has pioneered many new methods for offshore cathodic protection life extension over the years and has learned many lessons. The ACA works...

Too often we as engineers and managers of critical infrastructure focus on the technical details in a bid to control corrosion. We focus on the design and the performance of the products we specify to ensure we eliminate corrosion from our assets. However, our experience tells us that over time, the elements of nature takes...
