Deepwater Corrosion Services explores improved cathodic protection
Corrosion control firm Deepwater Corrosion Services plans to cut the costs of protecting cathodes by providing a better-designed, more efficient system. Cathodic protection is often seen as a retrospective issue rather than something to be planned for, which leads to shortened equipment lifespan. Deepwater Corrosion Services’ proposal is for a “plug and play” system that is a simple cathodic protection stab and anode sled, which offers monitoring abilities and easier installation than current methods.
Deep-water cathodic protection largely relies on sacrificial anodes. Such consumables draw corrosion to a specified location, thereby preserving the integrity of steel assets.

But due to the persistent nature of corrosion, the protected structures must be tested at intervals to ensure the anodes are still drawing the corrosion away from the steel, and depleted anodes must be replaced periodically.

“Everything that goes in needs cathodic protection,” Matthew Taylor, head of science and technology at Deepwater Corrosion Services, says.

Designing a better cathodic protection system from the beginning of a project’s life means preventing rust issues down the line, reducing life extension costs, improving the ability to monitor, and reducing repair costs as well as potentially extending the life of the asset, according to the company.
