Abstract
This report builds on deliverable D3.1 which identifies current practices being adopted by wave and tidal device developers in undertaking concept device performance appraisal. As well as identifying the technical practices being adopted it also set out to establish the objectives for developers to engage with such an appraisal exercise early in a technology’s development phase and the identification of inconsistencies and scope for error introduction with the different approaches being adopted. This identified that a range of analytical and computational techniques being adopted, ranging from steady state spreadsheet calculations through to the use of dynamic simulation models; and that a large scope for error introduction exists due to the simplified assumptions being adopted when establishing background conditions and populating models. In light of this, this report set out to introduce a best practice approach for undertaking a 1st stage performance appraisal of conceptual wave or tidal energy converters.
