Advances In Offshore Wind Energy Development

Abdoullah A. Afjeh


Offshore wind energy is conceptually attractive for sustainable energy production because of the abundance of the area, steady and high winds, and proximity to population centers. The global installed wind power capacity exceeded 318 GW in 2013, contributing to produce the electricity use of 8% and 4% in the EU and the US, respectively. However, much of this power capacity comes for onshore wind turbine installations. These have been due to higher cost of energy from offshore wind, considering both capital costs of system acquisition and operation. However, the levelized cost of offshore wind energy has been steadily declining over the past several years because of the rapid pace of innovations in system design, installation technology and practices, as well as improved siting methods. Radically different designs of the offshore wind turbine from conventional onshore designs promise even larger cost reductions and parity with land based wind turbine generator systems within a decade. Prominent among these developments is the development of very large two-blade, downwind turbine systems. This talk will discuss the offshore cost drivers and novel development approaches and turbines designs these costs for dedicated offshore large wind turbine systems.
