Über dieses Buch

This book provides a state-of-the-art review of floating offshore wind turbines (FOWT). It offers developers a global perspective on floating offshore wind energy conversion technology, documenting the key challenges and practical solutions that this new industry has found to date. Drawing on a wide network of experts, it reviews the conception, early design stages, load & structural analysis and the construction of FOWT. It also presents and discusses data from pioneering projects. Written by experienced professionals from a mix of academia and industry, the content is both practical and visionary. As one of the first titles dedicated to FOWT, it is a must-have for anyone interested in offshore renewable energy conversion technologies.

Looking Back

Abstract

Offshore wind turbines are a leading renewable energy technology with significant potential to support the drive for a low-carbon economy in Europe. Since the installation of the first offshore wind farm in Denmark in 1991, the installed capacity of offshore wind farms in Europe has grown significantly. By the end of 2015, the cumulative installed offshore wind capacity in Europe was over 11 GW, which is sufficient to cover 1.5 % of the EU’s total electricity consumption (EWEA 2016).

The Offshore Environment

Abstract

An accurate assessment of the offshore environment, including the meteorological, oceanographic and other relevant environmental conditions, is fundamental to the design of FOWTs.

Overview of Floating Offshore Wind Technologies

Abstract

In this chapter a review of the key technology components that can be directly associated with FOWTs is presented. The main options for the key technology component that make up a FOWT are discussed in detail, namely the types of support structures (Sect. 1), wind turbines (Sect. 2) and mooring systems (Sect. 3). The main objective of this chapter is to provide the reader with a clear overview of the relative advantages and disadvantages of each key design option.

Modelling of Floating Offshore Wind Technologies

Abstract

The modelling of FOWT forms a critical stage of the design process, as it allows a fully coupled dynamic assessment of the response of the concept while accounting for blade-rotor dynamics, support structure motions and mooring dynamics. For both new and for existing concepts, modelling offers the potential to test, in controlled environments, a series of assumptions and scenarios at a relatively minor cost. Two fundamental modelling approaches can be followed: numerical and experimental.

Key Design Considerations

Abstract

Floating offshore wind turbines are exposed to varied combinations of environmental loads. The theories behind how the different environmental forces cause loading on the wind turbine have been covered in Chapter “Modelling of Floating Offshore Wind Technologies”; Sect. 1 of this Chapter addresses the combinations of environmental situations which need to be investigated when designing a floating wind system as well as how they are transferred into design fatigue and extreme loads.

State-of-the-Art

Abstract

In this chapter, a review of some of the prototype FOWT devices that have been deployed to-date is presented. The technologies overviewed throughout the chapter are: Principle Power’s semisubmersible WindFloat device; the Hywind spar under development by Statoil; the Goto Island project in Japan and the SWAY system.

Looking Forward

Abstract

Floating wind technology has a number of key advantages compared to the more conventional offshore, bottom-fixed wind. Floating solutions allow the offshore wind industry to move towards high-yield sites, often found in deeper waters. Also from the fabrication side significant scale benefits can be anticipated. In a wind farm, bottom-fixed structures frequently require special designs for the individual foundations whereas all floating structures within a wind farm can be identical, being less restricted by water depth and local site constraints.
