The Performance Assessment of Wave and Tidal Array Systems (PerAWaT) project, launched in October 2009 with £8m of ETI investment.The project delivered validated, commercial software tools capable of significantly reducing the levels of uncertainty associated with predicting the energy yield of major wave and tidal stream energy arrays. It also produced information that will help reduce commercial risk of future large scale wave and tidal array developments.
This deliverable describes the current implementation status of the wave energy converter (WEC) numerical modelling software being developed by Gerald Hassan and Partners Ltd under the PerAWAT project.The report contains details for implementing the derived methodology in the time domain to analyse arrays in regular and irregular waves, such that it could be replicated by a 3rd Party. Initial results related to the influence of several design variables are presented. A detailed description and assessment of the performance of different fundamental device concepts and power take-offs is included. Implications for the further model development are discussed.The report is organised in nine sections which give a detailed overview of:Section 1:The scope of the documents and its key objectives ;Section 2:The architectureof the developed code, the core aspects of a multi-body dynamic solver and key time-domain implementation details;Section 3:The hydrodynamics module ;Section 4:The wave analysis module and its functionality;Section 5:The moorings module and its functionality(exemplified via a case study);Section 6:The power take-off (PTO) and control modules and their functionality;Section 7:The optimiser module and its functionality;Section 8: Case studies that outline initial results;Section 9: A summary of the key features implemented to date and planned extensions
