The quest for renewable energy sources leaves us questioning the consequences on our oceanic ecosystems.
Groundbreaking Underwater Energy Distribution System for Offshore Wind Turbines Tested off the Coast of Norway
In a significant stride towards cleaner and more sustainable energy, a pioneering project is currently in progress off the southwest coast of Karmøy, Norway. The Subsea Collector, an innovative energy transmission technology for offshore wind projects, is being demonstrated in this initiative.
This project, spearheaded by the Norwegian company Equinor, is the world's first underwater energy distribution system for floating offshore wind turbines. The testing phase is being carried out by Aker Solutions, with support from government funding and industry collaborations.
The Subsea Collector electrically connects multiple wind turbines in a star configuration, reducing costs by 10% in 1GW floating offshore wind farms. This innovative design uses less cable and accelerates installation, making it a game-changer in the offshore wind energy sector.
Currently, the Subsea Collector is deployed with two floating offshore wind turbines, 10 kilometers off the coast. Next year, the test area will expand to seven floating offshore wind turbines, demonstrating the potential of the Subsea Collector technology.
The Norwegian Marine Energy Test Centre (METCentre) is involved in the testing of this project, ensuring rigorous evaluation and validation of the technology. The testing is also part of Europe's efforts to provide clean energies, reflecting the continent's commitment to a greener future.
In addition to Aker Solutions, several other companies are contributing to the project. Windstaller Alliance, a union between Aker Solutions, DeepOcean, and Solstad Offshore, will install the initiative. ABB provides underwater equipment with monitoring and data acquisition control for the underwater collector, while Benestad offers a 66 kV wet-mate connector system for the underwater wind turbines.
However, this pursuit of clean energies is leaving fewer areas untouched for enjoyment in their natural state. Underwater mining is a new player in the radical change that the seas are undergoing. As with any technological advancement, it is crucial to balance the need for clean energy with the preservation of our natural resources.
This project, if successful, could redefine the layout of offshore wind farms, paving the way for more efficient and cost-effective renewable energy solutions. The Subsea Collector is a promising step towards a cleaner, greener future for Norway and the world.
