What's Happening?
Researchers from SINTEF, in collaboration with Aker Solutions, Sarens, and BOA, are testing a new method to transport and install substructures for fixed offshore wind turbines using an unusually wide
barge. The barge, measuring 166 meters in length and over 73 meters in width, is designed to carry multiple substructures simultaneously. This approach aims to reduce the reliance on large crane vessels, of which only a few exist globally. The tests, conducted at SINTEF’s Ocean Basin in Trondheim, have shown promising results, aligning well with prior numerical analyses. The barge is equipped with a lifting frame and hinge system, allowing it to lower to a depth of over 30 meters, facilitating the floating or lifting of cargo using smaller vessels. The project is part of the WindRise initiative, which seeks to enhance the efficiency of offshore wind turbine installation.
Why It's Important?
The development of this wide barge technology could significantly impact the offshore wind industry by reducing the need for large, expensive crane vessels. This innovation could lower installation costs and increase the accessibility of offshore wind projects, potentially accelerating the adoption of renewable energy. The success of this project could also bolster the Norwegian supplier industry, enhancing its competitiveness both nationally and internationally. By providing a more cost-effective and efficient method for installing wind turbines, this technology could contribute to the global transition towards sustainable energy sources.
What's Next?
Further work is needed to refine the unloading process of the substructures from the barge and their placement on the seabed. The project team will continue testing to optimize these procedures. If successful, this method could be adopted widely, influencing future offshore wind projects. Stakeholders in the renewable energy sector, including policymakers and industry leaders, may take interest in this development as it promises to reduce costs and logistical challenges associated with offshore wind installations.
