Whitepaper ICCP vs GACP

The corrosion of metallic materials in marine environments—such as the infrastructure in offshore wind farms—has been a problem for as long as people have been utilizing metals in water. This is the reason why corrosion protection mechanisms exist. One of the long-standing ways of protecting submerged metallic infrastructure is to use cathodic protection. While cathodic protection methods have been around for a long time, modern-day solutions are able to implement more effective potential controls and monitoring approaches (such as the integration with SCADA systems) that are highly beneficial for offshore wind environments.

CORROSION Calls for the sustainable protection of offshore wind farms

CORROSION today launched an awareness-raising campaign about the need for sustainable solutions that protect not only offshore wind turbine foundations from corrosion, but also the world’s seas and oceans.

“Few people realize that many offshore wind farms are far more eco-friendly above water than below it,” said Niels Ros, Manager Offshore Wind at CORROSION. “The traditional method to protect these structures, dates back to the 19th century and discharges huge quantities of metals and heavy metals into the seawater.”

The awareness campaign will begin by highlighting the benefits of Impressed Current Cathodic Protection (ICCP) systems to companies in the offshore wind energy sector through a special landing page on CORROSION’s website.

Other activities will include engaging with politicians and marine environmental organizations, hosting special events for key industry players at CORROSION’s virtual laboratory site, and offering to assist companies in the wind sector through the use of the R&D facilities at the CORROSION laboratory. The media are also invited to contact CORROSION to arrange a special tour of the laboratory facilities.

“With global offshore wind capacity projected to increase fifteen-fold in the next two decades, we believe in 21st century solutions for 21st century equipment,” said Niels. “ICCP systems provide all the protection that wind farm foundations need, but without polluting marine environments. What’s more, they have a far smaller carbon footprint than traditional protection methods.”

Hollandse Kust Zuid

A new offshore wind park will arise off the coast of Saint Nazaire in France next year. And we got the honor to protect all 80 turbines against corrosion with our ICCP system! Inside and outside. Assigned to us by Smulders. Construction recently started and takes place in Antwerp, Belgium. Park construction will start next year.

Introducing UV-C Onshore

We’re excited to announce that we now also offer a sustainable anti-fouling solution for onshore applications. The UV-C Cooler can protect against biological fouling at surface water installations. As we speak, we are working on our first project in the Netherlands; Bergsche Maas. A new built water inlet station that leads river water to a reservoir which is a source for drinking water. Soon more, so stay tuned!

 

Carbon Footprint – ICCP vs Sacrificial aluminium anodes

Offshore wind energy is at the forefront of many important discussions going on in the world today. As companies are being pushed to reduce their carbon footprint and decrease reliance on fossil fuels, wind energy is an extremely interesting option. Even though wind energy seems ideal, the actual benefits it carries in regard to sustainability are not always what they seem. One of the variables has to do with how these massive turbine constructions are protected from corrosion.

The steel foundations, the monopiles, jackets, tripods, and multi-piles all require cathodic protection. Traditionally, sacrificial aluminium anodes have been used most often. However, contrary to certain prejudices in the industry, an impressed current cathodic protection system (ICCP) does the job just as well, and with many significant advantages over aluminium anodes. Advantages which reduce both costs and carbon footprint.

CORROSION entered the Offshore Wind Industry in 2004. We took our experience and technology from other fields to create and implement ICCP systems to meet the specific needs of this sector. And we’ve been extremely successful. As the market leaders in this area, CORROSION wants to clarify and dispel misconceptions surrounding the use of ICCP in Offshore Wind.

Looking at environmental impact, ICCP beats aluminium anodes in every way. The Global Warming Potential (GWP) of aluminium anodes is approximately 11 times higher than ICCP systems when it comes to coated structures and 5 times higher for uncoated structures. With regard to abiotic depletion, the impact of aluminium anodes is +/- 2300 times higher with coated structures and approximately 1000 times higher with uncoated structures.

Moreover, ICCP systems release virtually no toxic material into the environment. Sacrificial anodes, on the other hand, release enormous amounts of toxic waste as they dissolve.

ICCP is definitely greener, but it also has major advantages in relation to design, TCO, installation, and real time onshore monitoring. And, it’s more cost effective, both in the initial purchase and over the long haul. We are convinced that the pros definitely outweigh the cons.
