Applications of cathodic protection

When and where can cathodic protection be applied?

Two conditions

Vandervelde Protection is active in the cathodic protection for all possible applications. A requirement to apply cathodic protection is that a circuit is created with:

  • an electric (metallic) contact between the surface to be protected and the rectifier or sacrificial anode and with
  • an electrolytic (in water or moist soil) contact between the rectifier or sacrificial anode and the surface to be protected.

For this reason it is not possible to protect surfaces without electrolyte contact. This makes it impossible to protect steel surfaces above the liquid surface or the external tank surface above ground. A suitable coating can prevent atmospheric corrosion.

A few applications of cathodic protection

As soon as the conditions above are met, cathodic protection can be applied. There are a few examples of applications of cathodic protection:

  • jetties, piers and quays in port or offshore facilities,
  • pipelines and tanks in oil and gas facilities, among others,
  • concrete floors, roofs, bridges etc.

Please have a look at a couple of our projects.

Where does Vandervelde Protection apply cathodic protection?

Vandervelde Protection is active in the design, delivery, installation, monitoring and maintenance of cathodic protection systems for a wide range of applications as:

  • Cathodic protection of port facilities, such as jetties, quays and piers.
  • Offshore cathodic protection applications offshore.
  • External cathodic protection of buried pipelines.
  • External cathodic protection of buried tanks.
  • Internal cathodic protection of tanks.

Apart from the design and delivery of complete cathodic protection systems, Vandervelde Protection also delivers the required cathodic protection materials. Read more about our cathodic protection services.
