HAW-Hamburg: Multi-Rotor System Seminar 2025

Multi-Rotor System Seminar | German version below

Di, 14.10.2025, 10:30 – Mi, 15.10.2025, 16:30 Uhr
HAW Hamburg | Auditorium at Berliner Tor 21 | 20099 Hamburg

Recent events, such as the launch of Mingyang’s 16.6 MW dual-turbine floating wind platform or the NOK 1.2 billion grant to Wind Catching Systems for the deployment of a commercial demonstrator unit of a multi-turbine floating wind platform, show more than ever the importance and possibilities of multi-rotor wind turbine systems (MRS) in the energy transition.

In order to discuss current developments and research of MRS, we are again organising a two-day international Multi Rotor 2025 seminar.

The Multi-Rotor System Seminar 2025 will take place on:

Date: Tuesday, 14 October 2025 and
Wednesday, 15 October 2025
Location: HAW Hamburg auditorium at Berliner Tor 21, 20099 Hamburg (Germany)

The following conference schedule is constantly being updated:
