This research project is founded by the Future Fuels Cooperative Research Centre (CRC), which in turn is supported by most major players in the Australian natural gas industry. For a detailed list of partners please visit the CRC website.
The project aims to develop advance low-cost methods for repairing and treating coating defects on underground steel pipelines. Coating repair costs for buried pipelines are an important barrier for the proactive corrosion protection (CP) of these assets.
Even though it is well known that coatings can fail in such a way that hinders the effectiveness of CP and allows corrosion to take place (dis-bonded coatings), operators can only economically repair defects that present measurable metal losses. This problem becomes increasingly important as assets age and coatings systems degrade more extensively, which sets external corrosion as the main reason for downgrading, re-purposing or abandoning pipelines.
Most of the direct cost of coating repairs is not associated to the coating repair itself, but to the required digging operation. This project will develop streamlined methods for local coating repair and treatment that do not require uncovering the pipe. In particular, the focus will be on the development of corrosion mitigation fluids and a delivery method to inject them near coating defects along the pipe.
The research has two main areas that require the development of new knowledge. One area is to develop and validate an innovative keyhole excavation process to access the coating damage at a low cost and without completely uncovering the pipe. Validation will require to perform a series of excavation in field conditions.
The other area is to develop and validate the low-cost fillers to be introduced around the coating damage to mitigate further corrosion. Although most of the development will involve the use of low scale tests and typical characterisation techniques used in the corrosion and coatings fields, full scale validation of the effectiveness of corrosion mitigating fillers will also be required.
