The Carbon Trust would like to thank everyone who has contributed their time and expertise during the preparation and completion of these studies. Disclaimer The key findings presented in this report represent general results and conclusions that are not specific to individual floating wind concepts. Caution should therefore be taken in generalising findings to specific technologies. It should be noted that information and findings do not necessarily reflect the views of the supporting industry partners but are based on independent analysis undertaken by the Carbon Trust and respective external technical contractors.
