7th International RAVE Workshop April 30th, 2026 in Hamburg

This year's International RAVE Workshop 2026 was organized as a hybrid event and took place on April 30th in Hamburg, Germany.

The public workshop was free of charge and offered a well-established space for yearly knowledge transfer and lively exchange on offshore wind-related topics. Current research findings using the data from alpha ventus were presented and questions from participants were discussed. The Workshop language was English.

One of this year's focus were discussions and presentations from research and industry on decommissioning and related topics. Lively discussed in a panel discussion was the question what further use the offshore industry and Germany can gain from alpha ventus pioneering this era. For interesting contributions with a range of perspectives we hosted participants from industry, offshore organizations, federal and public authorities. The live audience and participants online were also included to discuss with the panel group.

alpha ventus is the first German wind farm to reach its design life. As an offshore pioneer in this process it will be followed by many large wind farms.

The breaks provided many options for lively discussions on specialist topics. New contacts were established between science, authorities and industry and existing networks in an after-workshop-networking-time after closure.

The program with the presentations is published here, the available presentations can be found below for download.


If you intend to present your scientific work with RAVE data at one of the following occasions (e.g. RAVE Forum) or contribute a talk on decommissioning topics please send a mail to raveworkshop@iwes.fraunhofer.de.
