This joint development strengthens structural resilience while significantly reducing material usage, supporting Ecowende’s ambition to build an offshore wind farm in harmony with nature.

Over a 36-month collaboration, OES and Ecowende developed a welded ICCP anode system specifically designed for boat landing ladders. Traditionally, these systems rely on bolted connections in areas exposed to high structural loads and strong currents.

The new welded design eliminates these bolted interfaces, improving structural robustness and long-term reliability. It also ensures complete cable protection for both ICCP anodes and reference electrodes, safeguarding full functionality throughout the asset’s service life.

This innovation builds on OES’s extensive experience in offshore cathodic protection solutions and demonstrates how project-specific engineering can improve both durability and sustainability. By integrating corrosion protection directly into the structure, the solution sets a new benchmark for boat landing protection within offshore wind foundations.

Sustainability is central to Ecowende’s vision. The boat landing-mounted ICCP system significantly reduces material usage compared to traditional galvanic anode systems.

Where conventional systems would require approximately 425 tonnes of sacrificial anodes across the project, the ICCP solution uses less than 750 grams of Mixed Metal Oxide (MMO) per system. This dramatic reduction in material demand lowers environmental impact while maintaining optimal corrosion protection performance.

By combining engineering innovation with responsible material selection, OES supports Ecowende in delivering reliable renewable energy infrastructure aligned with the Netherlands’ energy transition goals.
