OEG Energy Group Limited (“OEG”, the “Group”), a leading offshore solutions business, is pleased to announce that OEG Renewables business Bluestream Offshore B.V (“Bluestream”) has recently performed upgrades to their innovative ICCP-SAM tool, which has been awarded two contracts for the installation of ICCP systems on offshore wind farm monopiles.
Developed in response to growing market demand and in collaboration with CORROSION, a market leader in the protection of offshore wind turbine foundations against corrosion, the ICCP-SAM (Impressed Current Cathodic Protection - Subsea Assembly Method) tool is specifically designed to remotely install ICCP anodes on monopile foundations of all sizes, anywhere on the foundation and even in the roughest ocean conditions.
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.
Rutger Lieverse, Commercial Manager of Bluestream said: “By upgrading our ICCP-SAM tool, we’re not just improving technology—we’re ensuring the future resilience of offshore wind infrastructure, standing stronger against corrosion and the harshest ocean conditions.”
Bluestream has several research and development projects underway alongside the ICCP-SAM, including solutions for mobilising inspection probes, performing inspections on subsea locations and sampling marine growth on offshore wind turbine foundations.
The continued investment by OEG Renewables in subsea tools and solutions demonstrates a commitment to pioneering innovation in the offshore renewables sector, providing sustainable and scalable solutions for a range of subsea challenges.
