International RAVE Workshop 2023

The International RAVE Workshop 2023 took place on May 11, 2023.

We are pleased to have again offered the International RAVE Workshop and successfully finished it in hybrid form. The workshop was held in Hamburg from 10:30 am to 5 pm (CEST) and was free of charge. We would like to thank the Federal Maritime and Hydrographic Agency (BSH) for offering hospitality in their facilities and for their technical support. During the event, participants could dial in online at any time and according to their own interest.

Once more, the workshop offered a space for knowledge transfer and lively exchange on offshore wind related topics. Current findings from research with data generated from alpha ventus were presented and subsequently discussed based on questions from the online chat and by participants on site. The breaks were also filled with lively exchanges on specialist topics. Contacts between science, authorities and industry were newly created and existing networks revived.

The conducted program can be found here on our website. Below in the grey boxes the presentations are available for download with friendly speaker´s permission.

We were happy about the numerous participation, positive feedback and therefore look forward to the next International RAVE workshop in 2024.

The International RAVE Workshop 2023 was divided in 3 blocks.

Bernhard Lange as project leader for the RAVE coordination and Nico Nolte /Federal Maritime and Hydrographic Agency (BSH) started the overall day event in the Hamburg location.
It was co-moderated by Kai Herklotz (BSH) and Tanja Griessmann (Leibniz University Hannover) and structured with discussion filled breaks and networking in three blocks:

  • 10:30 CEST: opening & introduction, presentations from industry working with RAVE data
  • 13:00 CEST: international presenters and German RAVE scientists
  • 14:40 CEST: modelling wakes and loads, environmental topics, discussion
