As the world transitions to cleaner energy, offshore wind farms have become an attractive investment. However, sea floors can vary widely in depth and composition, making a clear understanding of geological conditions critical to ensuring stable long-term operations. As one of the first steps to developing the Norfolk Boreas Offshore Windfarm off the coast of the United Kingdom, Vattenfall needed to incorporate the terrain characteristics into their design, but previous applications did not provide the level of detail needed. With Oasis montaj, design teams quickly processed data into a terrain model, creating an accurate representation of the site. The information will help them lower the amount of steel needed for construction, eliminate the risk of structural failure, and ensure the production of zero-carbon energy.
