What's Happening?
Researchers from SINTEF, in collaboration with Aker Solutions, Sarens, and BOA, are testing a new method for installing offshore wind turbine foundations using an extra-wide barge. This barge, measuring 166 meters long and over 73 meters wide, can transport
multiple substructures simultaneously, potentially eliminating the need for large crane vessels. The barge can be lowered to a depth of over 30 meters, allowing for the cargo to be floated out or lifted using smaller, more accessible vessels. Initial tests conducted at SINTEF’s Ocean Basin in Trondheim have shown promising results, aligning well with prior numerical analyses.
Why It's Important?
The development of this wide barge technology could significantly reduce the costs and logistical challenges associated with offshore wind turbine installation. By minimizing the need for specialized crane vessels, the industry could see a reduction in installation expenses, making offshore wind projects more economically viable. This innovation could strengthen the Norwegian supplier industry for offshore wind, enhancing its competitiveness both nationally and internationally. The ability to efficiently install wind turbines is crucial for the expansion of renewable energy infrastructure, contributing to global efforts to transition to sustainable energy sources.
What's Next?
Further testing and development are required to refine the unloading and positioning process of the substructures on the seabed. The project team will continue to explore the barge's capabilities in various wave conditions and work on optimizing the hinge system for better performance. Successful implementation of this technology could lead to widespread adoption in the offshore wind industry, potentially influencing future design and construction standards for wind turbine installations.
