This is the most authoritative single volume on offshore wind power yet published. Distinguished experts, mainly from Europe's leading universities, have contributed a collection of peer reviewed papers on the interfaces between wind power technology and marine engineering. The range of issues covered by the book include: wind as a resource; wind power generation; connection to the grid; the marine environment and engineering issues particular to it.
This book is essential for academic departments of mechanical engineering/energy engineering/ renewable energy. Offshore wind power generation will be the driver of the offshore industry for the foreseeable future: all organisations involved in offshore engineering should have this book.

John Twidell works independently as an academic consultant and writer in renewable energy and sustainability, and as Director of the AMSET Centre Ltd. He previously held the Chair in Renewable Energy at De Montfort University and was Director of the Energy Studies Unit of Strathclyde University. He has also held appointments at Universities in Africa and the South Pacific. He has served on the Boards of the British Wind Energy Association and the UK Solar Energy Society, on committees of the Institute of Physics and as an adviser to the UK Parliamentary Select Committee on Energy. Practical experience in wind power has included management of a 3 MW (60 m) wind turbine and other smaller wind turbines on Orkney, northern Scotland. He is a Board member of Westmill Windfarm Co-operative. Presently, he is Editor Emeritus of the academic journal `Wind Engineering', having been General Editor from 1998 to 2007. He is a visiting lecturer at the Environmental Change Institute, University of Oxford (MSc in Environmental Change, Energy Module), and the School of Aeronautics and Engineering, City University, London (MSc in Energy, Environment, Economics and Technology). His co-authored textbook with A.D. Weir, `Renewable Energy Resources' (second edition 2006, published by Taylor Francis) sells worldwide, mainly on postgraduate courses. He has written # 100 published papers on renewable and sustainable energy, and chapters in 9 other books.
Gaetano Gaudiosi graduated in Naval Engineering at Naples University in 1959, and now works independently as a consultant on offshore and onshore wind energy and other marine renewable energies. From its foundation in 2006, he has been president of the not-for-profit association OWEMES, emphasising the Mediterranean and Southern European seas. He is a Board member of ATENA (Associazione di Tecnica Navale) Rome Section and ANIV (Association Nazionale Ingegneria del Vento, 2001-2007). Previously he was an officer in the wind energy programs of ENEA (Project Manager 1980-1987 for MEDIT 300 KW and GAMMA 1.5 MW wind turbine; senior consultant and E.C. Italian project leader 1990-2001), Italian Member in the IEA Wind R& D Implement Agreement 1984-1990) and European Commission Expert for the evaluation of wind and ocean energy project proposals. From 1961 to 1980, he worked in nuclear energy, with experience in testing thermal critical phenomena in the reactor core (BWR and PWR) in Italy, USA and Sweden. From 1984, he has chaired the triennial European Seminar OWEMES in Italy (Rome 1994; La Maddalena 1997; Siracusa 2000; Napoli 2003; Civitavecchia 2006). He is author of papers on nuclear energy and wind energy, with particular attention to the offshore wind power applications presented in international conferences since 1992. He co-edited a special issue of the journal `Wind Engineering', reviewing offshore wind energy. Teaching activity in Wind Energy has been carried out for many years in Italy and other countries, recently including the e-learning ENEA-UNESCO course on offshore wind energy.
