Oceans of Energy, in partnership with CrossWind, has achieved a critical milestone in the development of the world’s first offshore solar farm connected to an operational offshore wind farm. The dynamic subsea power export cable—a key component of the HKN1 project—has been successfully tested, delivered, and is now ready for installation.

Following a successful Factory Acceptance Test at the NKT production facility in Sweden, the cable was transported to the project site at Hollandse Kust Noord in the Dutch North Sea. This advanced cable will soon connect the HKN1 offshore solar system to the existing offshore wind infrastructure, creating an unprecedented integration of solar and wind energy at sea.

“Initially, sourcing a dynamic subsea power export cable was challenging due to the rough wave conditions of the North Sea.” said Tijmen Smit, Project Manager HKN1 at Oceans of Energy. “However, with the advanced properties of the NKT cable, our team executed complex engineering to achieve an optimal design configuration. The next step is installation, after which this cable will be the first cable in the North Sea that supplies offshore solar energy to an offshore wind turbine grid.”

Jeroen van Loon of CrossWind added: “Crosswind is excited to see this milestone reached through the collaborative efforts of NKT and Oceans of Energy. With the delivery of the dynamic subsea power export cable, we’re ready to connect for the first time in the world an offshore solar farm into the infrastructure of an offshore wind farm.”

This development marks a major step forward in the HKN1 project and the broader transition toward hybrid renewable energy systems that maximize space, infrastructure, and environmental synergy at sea.
