This document constitutes Deliverable ‘D2.10 Assessment of Baseline Configurations and Specification of Final Configuration’ of the LiftWEC project. LiftWEC is a collaborative research project funded by the European Union’s Horizon 2020 Research and Innovation Programme under Grant Agreement No 851885. It is the intention of the project consortium that the LiftWEC project culminates in the identification of one or more promising configurations of a Wave Energy Converter operating through the use of a rotating hydrofoil that generates lift as the primary interaction with the incident waves.

This report details the process used to select the Final LiftWEC Configuration, as well as an outline specification of that configuration. The Final LiftWEC Configuration defines the subject matter for the investigations and assessments that will be conducted during Phase 4 of the project.

The selection of the Final LiftWEC Configuration was the culmination of a two-day all-consortium workshop held in May/June 2022. The aim of this workshop was to evaluate the four Baseline LiftWEC Configurations, leading to the selection of one of these Configurations as the Final LiftWEC Configuration. In preparation for the workshop, each technical work package prepared a short presentation on each of the Baseline Configurations. These presentations were used to disseminate work package opinions throughout the consortium before the LiftWEC Concept Evaluation Tool was used to quantitatively rank the four configurations in terms of their perceived suitability for further investigation and development. While these quantifications were intended to guide the decision, they were not binding in terms of the highest scoring configuration being selected as the Final LiftWEC Configuration.

Results of the quantitative evaluations suggest that the Spar-Buoy configuration holds the greatest potential for further development. While this ranking was not binding, after significant discussion of the options available it was decided that the Spar LiftWEC would indeed be selected as the Final LiftWEC Configuration. This decision was made by consensus and no objections were presented.

This document further details these activities before presenting an outline description of the Final LiftWEC Configuration. Appendices are also presented which provide both the workshop agenda as well as the work-package presentations assessing the four Baseline Configurations.
