Abstract
Ocean waves are an enticingly energy-dense renewable energy resource, yet Wave Energy Capture (WEC) systems remain an immature and underutilised technology. In their numerical study, [Asiikkis et al., 2023] found that cable length may be an effective tuning parameter for the maximisation of surge amplitude, for a Surge-based point-absorber WEC. The research in this paper attempts to experimentally validate the theoretical results, as well as uncover and explain any other trends of behaviour that are observed. The research is conducted by constructing a model moored floater and subjecting it to various cable length and wave conditions in a wave flume and measuring its response. Significant evidence indicating an indirect causal connection between cable length and surge amplitude was found, where cable length influenced the floaters’ harmonic frequency, maximising surge amplitude at harmonic number = 0.5. Therefore, cable length was shown to be an effective tuning parameter for the optimisation of surge behaviour, for the case where maximal surge amplitude is desirable. Further behavioural trends of interest were also discovered, and explanations and potential applications of the findings are discussed. Overall, the findings detailed in this study serve two purposes: to reinforce the prospect of using cable length as a tuning parameter for future surge-based PA-WECs, and to invite further research to explore the persistently ill-understood concepts.
