Pioneering the latest advancements in subsea corrosion protection
At OEG, innovation is an important part of our operations, and our research and development team is committed to developing innovative tools and services that allow us to deliver solutions and projects more safely, efficiently and reliably.
In the subsea field, we have developed various tailor-made tools for installing and inspecting subsea components, from idea and initial concept through to implementation and offshore operation.
The ICCP-SAM (Impressed Current Cathodic Protection - Subsea Assembly Method) tool
Impressed Current Cathodic Protection
One such development is OEG’s ICCP-SAM (Impressed Current Cathodic Protection - Subsea Assembly Method) tool, designed to remotely install ICCP anodes on monopile foundations of all sizes, anywhere on the foundation and even in the roughest ocean conditions.
Developed in collaboration with CORROSION, a market leader in the protection of offshore wind turbine foundations against corrosion, the ICCP-SAM represents OEG’s investment in ensuring the future resilience of offshore wind infrastructure.
Investing in technology upgrades
The latest upgrades to the ICCP-SAM focus on optimising both the installation process and the performance of the anode system, improving the reliability of the tool in challenging offshore subsea conditions. Significant improvements include a redesigned clamping mechanism, with the system now featuring four bolts to securely clamp onto the anode by interlocking two plates. The updated design eliminates the need for bolting directly onto the foundation, ensuring greater flexibility and durability and allowing the bolts to stretch and withstand higher pressures.
Improvements have also been made to the size of the system, resulting in an even more compact design which will allow for longer anodes which can cover a larger surface area of the monopile, improving the efficiency of cathodic protection over a broader region.
Field-proven results
The ICCP-SAM tool is currently being implemented by Equinor and Polenergia on the Baltyk 2 & 3 offshore wind farms in Poland, where it will protect 100 monopile foundations as part of OEG’s first engineering, procurement, construction and installation (EPCI) contract.
This milestone not only reinforces the value of the ICCP-SAM solution but also underscores OEG’s commitment to delivering sustainable, long-term services to the Polish offshore wind sector as part of our broader European presence.
