UV-C Whitepaper

We’re excited to introduce the new whitepaper ‘UV-C and laid up vessels’. CORROSION has developed the first maritime cooling system that prevents marine growth, even when the ship is laid up. Rather than chemicals, it relies on the disinfecting power of a particularly energetic type of ultraviolet radiation called UV-C.

Box coolers, the most commonly used cooling systems for vessels up to 120 meters, rely on running engines to prevent marine growth on the tubing that releases engine heat to the surrounding water. When the vessel is laid-up, there’s a significant chance that, over time, an ecosystem of marine organisms will establish itself on the cooler. Removing it typically requires costly dry-dock maintenance, yet leaving it there at the very least decreases efficiency and, in the worst-case scenario, will cause major operational and safety issues down the line.

CORROSION and Amphibious Energy join forces

CORROSION and Amphibious Energy today announced the launch of the new ICCP-POD, an environmentally friendly alternative to using diesel generators to supply energy during the construction phase of wind turbines, and sacrificial anodes to protect turbine foundations against corrosion.

The ICCP-POD combines two advanced technologies. The EnergyPod, developed by Amphibious Energy, is an easy-to-transport autonomous energy plant that uses sun, wind, batteries and intelligent electronics to provide sustainable energy during the 18-month construction of wind turbines, meaning that costly and environmentally unfriendly diesel generators are no longer required.

To protect against corrosion during this construction phrase, CORROSION developed compact ICCP (Impressed Current Cathodic Protection) units. By using an electronic current supplied by the EnergyPod, these represent an innovative eco-friendly alternative to sacrificial anodes, which discharge large quantities of metals and heavy metals into the water. When the wind turbines are installed and grid-connected, the energy supply for the ICCP system is switched from the EnergyPod to the wind turbine itself.

“CORROSION was the first company in the world to develop a cost-effective, easy-to-maintain and environmentally friendly anti-corrosion solution for wind turbines foundations,” said Niels Ros, Manager Offshore Wind at CORROSION. “We are delighted that through this partnership with Amphibious Energy, we are also able to offer the same sustainable protection solutions during the construction phase of wind turbines.”

“By partnering with CORROSION, we are able to bring two unique technologies together, which will drive down the costs for the offshore industry to protect their installations from corrosion in a 100% green way. This represents a big step forward in achieving net-zero operations for the offshore industry,” said Willem van der Merwe, Director at Amphibious Energy.

The ICCP-POD delivers substantial cost savings compared to a diesel generator. In addition, further savings can be realized in other ways. For instance, by installing uncoated foundations, foundations with a single base coat or utilizing less carbon steel (corrosion allowance), depending on customer needs and design boundaries.

In terms of environmental performance, CORROSION’s ICCP unit provides major benefits. Over a 25-year period, CORROSION’s systems discharge approximately 1.5 million times less aluminum into the sea that traditional sacrificial anodes. Furthermore, the EnergyPod is also completely recyclable and can be re-used several times over a period of 5 to 10 years, so that the costs will decrease even further.

Light in the darkness

These are still challenging times for the maritime industry. As the coronavirus is disrupting trade all over the world, many shipping companies have no other option than to lay-up (some of) their vessels and wait for better times. CORROSION can at least help prevent a second problem from occurring and that is cooler fouling. Our UV-C Cooler protects against fouling even when the vessel is laid up.

The use of sacrificial anodes leads to the release of heavy metals and metals such as zinc and aluminum into the marine environment. The result? Over the 25-year lifetime of a wind farm, literally millions of kilograms of metal alloys can be discharged into the seawater. What’s more, the sourcing, transportation and maintenance of the metals used in sacrificial anodes, also comes with a significant carbon footprint. Thankfully this is not a problem without a solution. Find out how: https://www.corrosion.nl/gacp-vs-iccp/

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.”

Assigned to us by Smulders. Construction recently started and takes place in Antwerp, Belgium. Park construction will start next year.

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.
