Abstract

This Special Issue presents selected papers from EERA DeepWind‘2020, 15-17 January, Trondheim, Norway. This was the 17th Deep Sea Offshore Wind R&D Conference. The conference is hosted by SINTEF and NTNU and organized in cooperation with the European Energy Research Alliance (EERA) joint programme on wind energy. A total of 32 papers are included addressing the research topics of the conference▪ New turbine and generator technology▪ Grid connection and power system integration▪ Met-ocean condition▪ Operation and maintenant▪ Installation and sub-structures▪ Wind farm optimization▪ Experimental testing and validation▪ Wind farm control systemsAll papers presented in this special issue have gone through a careful peer-review organized by the international Scientific Committee of EERA DeepWind‘2020:Anaya-Lara, Olimpo, Strathclyde UniversityBadger, Jake, DTUBerkhout, Volker, Fraunhofer IWESBerge, Erik, METBredmose, Henrik, DTUCutululis, Nicolaos, DTUEecen, Peter, ECNHeggelund, Yngve, CMRKitzing, Lena, DTUKvamsdal, Trond, NTNUMadsen, Peter Hauge, DTUMcKeever, Paul, ORE CatapultMerz, Karl, SINTEF EnergiMunduate, Xabier, CENERMuskulus, Michael, NTNUNielsen, Finn Gunnar, UiBNygaard, Tor Anders, IFEReuder, Joachim, UiBRobertson, Amy, NRELSperstad, Iver Bakken, SINTEF EnergiTande, John Olav, SINTEF EnergiUhlen, Kjetil, NTNUVan Bussel, Gerard, TU DelftVan Wingerde, Arno, Fraunhofer rWESØkland, Ole David, SINTEF Acknowledgements The financial support from the Research Council of Norway covering a share of the cost of organizing the conference is greatly appreciated.
