Wind Propulsion Innovation Awards 2021

Wind Propulsion Innovation Awards 2021 – Virtual Awards Ceremony 

Following the key transport day at the COP26 today and to underscore the importance of positive, maritime decarbonisation projects and messages, the Wind Propulsion Innovation Award 2021 virtual awards ceremony was held on Thursday, 11 November from 0900-1030 UK time.

The 39 projects, papers and people were the shortlisted by a panel of judges drawn from across the industry, academia, wind propulsion advocates and some with general renewable energy/sustainability backgrounds. Judges Profiles  Altogether these categories have received over 40,000 votes.

“These awards have been an opportunity for us to celebrate just a small number of the positive wind propulsion developments in the industry. With a growing number of ships installed with wind propulsion systems and momentum building to deploy decarbonisation solutions that are ready to go today, we hope that these awards have provided the industry and wider public a glimpse of these exciting developments underway and the pipeline to come. We hope you will join us on Thursday!”  Gavin Allwright, IWSA Secretary General.

The awards are sponsored by American Bureau of Shipping (ABS), Thordon Bearings, Wärtsilä Marine Power, MARIN, The Royal Institution of Naval Architects (RINA), Kühne Logistics University (KLU) Hapag-Lloyd Center for Shipping and Global Logistics (CSGL), Dealfeng New Energy Technology, Econowind, Green Marine, Norsepower and Yara Marine Technologies.  MORE ABOUT OUR SPONSORS

The awards will be streamed live from Glasgow as part of the Malin Spotlight series and can be watched on using the password: ShippingPostCOP26_L1VE_GlaCOP26
