Work Packages
-
WP1 involves overseeing the project coordination, financial, and legal management of the MEGA-PTO project. This includes strategic and operational management, ensuring effective communication and collaboration between work packages (WPs), and meeting project goals and deliverables.
-
WP2 focuses on developing an integrated power take-off (PTO) design tool by combining existing magnetic gear and generator design tools, building a 1kW system for testing, and developing power electronic models. The validated tools will provide crucial data for WP3, demonstrating scalability and practicality for larger-scale PTO designs.
-
WP3 aims to design, optimise, and manufacture a 100kW MEGA-PTO system, demonstrating scalability for medium and high-power applications. Key objectives include developing an integrated design tool based on WPs 2 and 10, using it to design and build a 100kW system for testing, integrating power electronic control for fault tolerance, and conducting a technology assessment of the engineering and manufacturing processes.
-
WP4 aims to develop a comprehensive integrated model of all PTO components and create wave-to-wire models to estimate energy output in both simulation and hardware-in-the-loop (HIL) environments. It also seeks to identify improvements in the PTO architecture for future large-scale applications.
-
WP5 focuses on establishing the control architecture for the PTO system, developing algorithms to optimise power and energy output within system limits, and designing an advanced controller using machine learning for diagnostics and predictive maintenance.
-
WP6 aims to improve PTO reliability by using condition monitoring and preventative maintenance to prevent outages. It focuses on detecting key issues like stator faults and demagnetization with advanced diagnostic methods.
-
WP7 focuses on creating a framework to assess the large-scale impact of the project's innovations, helping to communicate their potential to stakeholders and support wave energy commercialization. It includes reviewing literature on life cycle analysis (LCA) and techno-economic frameworks for evaluating environmental and economic aspects of wave energy. The framework will be applied to case studies in WP8, guiding improvements in LCA and LCOE, with insights informing WP9’s analysis and road-mapping efforts.
-
WP8 aims to conduct a comprehensive investigation of the impact of the large-scale deployment of wave energy using the MEGA-PTO innovations, from the standpoint of the potential environmental impacts and the techno-economic implications and opportunities brought by the deployment of modular solutions. The insights obtained from the LCA and LCOE analyses will provide valuable information to the consortium and industry for establishing commercialization pathways after the project.
-
WP9 will evaluate the current and future capabilities of Europe’s wave PTO manufacturing and supply chain, assessing competitiveness and identifying training needs. It will develop a roadmap to enhance Europe’s production competitiveness in high-growth markets and provide a comprehensive review of materials and manufacturing methods using a PESTLE approach. The insights will inform the creation of a sustainable, circular economy roadmap for future wave energy converter PTO manufacturing.
-
WP10 is dedicated to testing and validating the integrated CGEN and magnetic gear technology at a 1 kW scale. This phase is crucial for verifying design algorithms, assessing efficiency and performance, and gathering data to refine system design and control. The insights gained will inform the testing protocols for WP11, ensuring optimized and effective validation for larger-scale systems.
-
WP11 involves testing the 100 kW MEGA Wave PTO prototype to validate its performance under field-relevant conditions. It aims to verify the technology's feasibility by assessing its response to static, dynamic, and field-simulated loads. The outcomes will guide future device setups and establish testing guidelines, with a focus on magnetic gearing behaviour under various forces.
-
WP12 manages external communication and results dissemination for the MEGA PTO Wave project. It aims to increase awareness of the project and its technological advancements, as well as highlight the benefits of wave energy.
