Topic of the proposed research: Innovative testing and analysis of load characteristics of floating ORE Technologies
Project summary: Physical model testing of ORE technologies is a standard process for advancement through the TRLs. However, for the majority of cases the testing only examines the dynamics and/or power production characteristics of a technology and provides very little information regarding structural loads. A number of WEC technologies in particular have found that this lack of knowledge of loading has had significant implications for full scale prototypes, resulting in failures or higher than expected fabrication costs. Developing improved/innovative methodologies to understand structural loads at low TRLs will enable a more complete understanding of the final design of a device, its fabrication process and the overall CAPEX. This will allow for a more accurate determination of the LCoE and thus a better assessment on the feasibility of a technology before large investment is required.
To examine load characteristics of scaled models attention needs to be given to the design of the model and modifications are required to enable measurement to take place. It is particularly complicated when uncertainties, sensor variations and noise in a wave basinare included. While some guidelines exist there is a strong and fundamental need to create a comprehensive set of benchmark for a clear guideline and recommendation around this process and to understand load measurement on scaled models. What to measure, how to measure, how much to measure, with what to measure, when to measure, how long to measure and how to eventually interpret them and link clearly to models must be through a benchmark and this project will directly address it. The PhD will entail the following work;
Literature Review to collate existing information relating to this subject. Particularly relevant is existing methodologies, instrumentation and scaling used worldwide. It will also establish the uncertainty and variations that exist and also what are the core aspects to consider.
A comprehensive numerical and statistical analyses will be carried out to establish the uncertainty and variation around the load monitoring and measurement aspects. A combined model and data-driven estimate will provide sensor placement strategies and handling uncertainties and variations. The effect of such measurements on design will be validated and established by physical testing on generic ORE technologies.
The work will establish monitoring strategies and their impacts for load monitoring and their links to model updating and digital twinning. It is expected that real-time algorithms will be developed for this and how load measurements will be interpreted and influence prototype design.
The PhD will produce publications that will provide guidelines, procedures and recommendation for ORE load quantification at low TRLs and will include sensor placement, interpretation, choice, monitoring strategy, scaling and testing methods and post-data.
