The foundations of the WTGs as well as an offshore substation are a crucial part of the infrastructure and have a significant impact on the total costs of an offshore wind farm. For each wind farm, the foundations have to be specifically design to fit the local circumstances, such as soil, depth, wave, permit, wind turbine and installation capacity. Wind Minds can support in the foundation type selection and basic design and specification for the tendering process. Furthermore, Wind Minds can assess detailed designs from a techno-economic perspective.
