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.

Abstract

The coastal zone is the host to many human activities, which have significantly increased in the last decades. However, sea level rise and more frequent storm events severely affect beaches and coastal structures, with negative consequences and dramatic impacts on coastal communities. These aspects add to typical coastal problems, like flooding and beach erosion, which already leading to large economic losses and human fatalities. Modeling is thus fundamental for an exhaustive understanding of the nearshore region in the present and future environment. Innovative tools and technologies may help to better understand coastal processes in terms of hydrodynamics, sediment transport, bed morphology, and their interaction with coastal structures. This book collects several contributions focusing on nearshore dynamics, and span among several time and spatial scales using both physical and numerical approaches. The aim is to describe the most recent advances in coastal dynamics.
