The project will analyse the damage tolerance of sacrificial coating systems, which could replace the combined systems, anodes and dielectric coatings currently used in the offshore industry.
The sacrificial coatings will be sprayed onto carbon steel and controlled damage will be produced before exposing them to seawater. The electrochemical monitoring will be carried out to understand the sacrificial protection offered by such coatings when damaged. The effect of temperature and salinity on the damage tolerance of such coatings will also be explored. Use of numerical models will also be explored to understand the effect of different service conditions on the performance of the selected sacrificial coatings, particularly in the presence of damage.
The development of a damage-tolerant system will directly impact safety since it will reduce the likelihood of unexpected failures, costs, and risks associated with offshore repair operations.
