Winning solution of foundations-structural supports in locations 30-50 m

Abstract

The suitability of each type of foundation-support (monopile, gravity-based and jacket) will be analyzed for the different conditions that can be found in locations with a draft of 30-50 m. Some of the most important considerations such as metocean loads, geotechnics, economic aspects, manufacturing, transportation, installation, operation and decommissioning, local content, etc. will be taken into account. Then, it continues with the establishment of a methodology for the decision making of the most suitable offshore wind turbine foundation. TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), a widely used multi-criteria decision-making method that allows for both quantitative and qualitative criteria to be considered in the decision-making process, will be employed. It has been verified in this document that the proposed methodology allows the decision of offshore wind turbine foundation according to the conditioning factors, enabling not only technical and financial feasibility of the offshore wind farm to be achieved, but also respect for the environmental impacts.
