NGI to lead research to economise offshore wind energy

Under the three year Redwin project, NGI will work with the Norwegian University of Science and Technology, Institute for Energy Technology, Statoil and Statkraft.

NGI has said that the development of offshore wind is crucial for a future without fossil fuels, however, overall costs need to be reduced in order to make offshore wind competitive.

“Today, the geotechnical engineers working on the foundations and the structural engineers working on the construction operate within separate professional fields,” said NGI in a statement. “There are no comprehensive tools that can combine the two areas, enabling them to jointly arrive at the best solutions.

“As a consequence, both expert groups often need to repeat their calculations several times before they can arrive at a solution that satisfies all needs. The engineering phases often take longer than scheduled, with no guarantees that the resulting solutions are the best possible. Since foundations represent 25 to 30% of total construction costs, there is a great potential for savings.  
“Redwin brings together experts from the two engineering fields, in order to jointly develop better methods.  The aim is to design new models describing soils and foundations that will be integrated with the computational tools used by structural engineers today. This will contribute to optimised engineering and design, resulting in less expensive offshore wind energy.”
