The deliverable establishes the first integrated controller-development framework for the MEGA WAVE PTO project. Starting from the WP4 modelling framework documented in D4.1 and D4.2, it provides preliminary controller settings, identifies PTO operating in envelopes for the three WEC types, and clarifies the main interactions between hydrodynamic response, PTO sizing and electrical-conversion requirements. The results form the technical basis for the next project steps, where more detailed PTO sub-system models, refined constraints, thermal and reliability considerations, and advanced predictive-control strategies will be progressively introduced.

Deliverable D7.1 establishes baseline specifications for the MEGA WAVE PTO system across three representative WEC scales: small, medium, and large. The report evaluates system performance, cost, and carbon footprint, providing a reference framework for comparison with existing technologies.
Case studies incorporate designs from project partners—Pure Marine, Mocean Energy, and Carnegie Clean Energy—and use site-specific metocean data from BiMEP (Spain) and EMEC (UK) to simulate realistic operational conditions. The deliverable supports system scalability, modularity, and maintainability while informing future development, lifecycle assessment, and cost-optimisation strategies.
-
Deliverable D7.2 presents a comprehensive literature review of Life Cycle Assessment (LCA) studies for Wave Energy Converters (WECs), examining environmental impacts across manufacturing, installation, operation, maintenance, decommissioning, and disposal. The report highlights key contributors to lifecycle emissions, with manufacturing identified as the dominant source, and underscores the importance of effective O&M strategies.
The review also analyses LCA methodologies, software tools, and data sources, providing a benchmark for assessing the MEGA WAVE PTO system. These insights will inform future LCA studies for MEGA WAVE PTO and support comparisons with existing wave energy technologies.

This deliverable presents a comprehensive assessment of current costs in wave energy, examining both capital and operational expenditures across 226 devices compiled in the open-access PRIMRE database. The study includes multiple technology types, generator configurations, and years of operation, with particular focus on attenuator, point-absorber, and pressure-differential WECs.
Results are scaled to present-day values to provide realistic cost benchmarks for mid- to late-2020s device fabrication. This assessment establishes reference values for capital and operational expenditure, which will be used in future MEGA WAVE PTO deliverables to measure the impact of technological improvements in modularity, scalability, and reliability of the CGEN generator.

For the EU to achieve its goal of becoming the first climate-neutral continent by 2050, it will need to accelerate the development and deployment of a diverse portfolio of renewable energy technologies. While established technologies such as offshore wind are expected to deliver the majority of near-term capacity, emerging and highly innovative technologies will play a critical role in supporting longer-term system resilience, diversification and cost reduction. Among these, wave energy presents a significant opportunity, with the potential to contribute meaningfully to Europe’s future net zero energy mix.
At the time of writing, the wave energy sector remains at an early stage of development. This creates a window of opportunity for Europe to establish a globally competitive position in both technology development and selected areas of the underpinning industrial supply chains. Central to this is the Power Take-Off (PTO) system, a high-value subsystem that represents a substantial proportion of total device cost and, by extension, the associated economic value. Securing the capability to design, manufacture and scale wave PTO systems within Europe will therefore be critical to retaining long-term socio-economic benefits, including gross value added (GVA) and high-skilled jobs. At the same time, there is a broader rationale for strengthening Europe’s position in PTO development to ensure that existing actors across the wave and wider renewable energy sectors retain and enhance their supply chain competitiveness.
However, developing a competitive PTO supply chain presents a complex challenge. It must be achieved within constrained timelines, alongside competing budgetary priorities across the European Union and its Member States, and in the context of increasing international competition, particularly from China. Without targeted intervention, there is a risk that key components of the value chain will be captured outside Europe.

This document defines the testing requirements for full-scale rotational wave energy power take-off (WavePTO) systems, with specific application to the MEGA Wave PTO 100kW demonstrator to be validated at the CWD Drivetrain test rig at RWTH Aachen.
Realistic validation of a WavePTO requires reproduction of both the torsional drive loads (the primary torque and speed inputs from wave-driven shaft rotation) and the non-torque loads (NTL) that arise from the physical forces acting on the submerged or surface-mounted device. Unlike conventional rotating machinery, WavePTO systems operate under reciprocating, stochastic loading, and are subject to combined bending moments, axial forces, and shear loads that couple with the primary drivetrain torque.
Neglecting NTL in laboratory testing leads to non-conservative validation and may obscure failure modes that are relevant in the field.
This document briefly surveys the physical origins of torsional and non-torque loads for three wave energy converter (WEC) device archetypes considered in the MEGA WAVE PTO project, derives the resulting test rig requirements, and defines an operating envelope that the 100kW test campaign must cover.
The deliverable contributes to the outcomes from T11.1 - Definition of test rig requirements specific to the MEGA PTO (M4-M8).

Deliverable D4.1 presents a unified simulation framework for the MEGA WAVE PTO system, integrating magnetic gears, the modular C-GEN generator, and reconfigurable power electronics into a comprehensive wave-to-wire model. Developed in MATLAB Simulink, the framework captures the coupled dynamics of the WEC, PTO subsystems, and power electronics, supporting performance prediction, lifecycle design, and optimisation of modular configurations.
The framework enables the evaluation of three representative WEC designs across European test sites (EMEC, UK and BIMEP, Spain), and underpins the development of advanced control strategies, hardware-in-the-loop testing, and test protocols. It establishes a foundation for simulating small- to large-scale PTO systems, ensuring accurate representation of mechanical, electrical, and control interactions.

The MEGA WAVE PTO project, with full title "MODULAR ELECTRICAL GENERATOR PTO SYSTEM FOR WAVE," seeks to create a fully integrated PTO system for wave energy devices, that can operate efficiently across various power capacities, from kilowatts to megawatts. The project will develop and demonstrate a smart, modular system incorporating novel axial flux magnetic gears, permanent magnet generator technology, and adaptable power electronics. This system will enhance energy production efficiency and environmental sustainability while being easier to manufacture, transport, install, maintain, remove, and recycle than existing alternatives.
Jointly funded by the EU Horizon Europe programme and UK Research & Innovation, MEGA WAVE PTO started in May 2024 and will run for 48 months. By the end of the project, it aims to significantly advance wave energy technology and contribute to the EU's NetZero targets by 2050.
Deliverable D6.1 - "Fault Diagnosis in MEGA-PTO" is a Report describing the developed diagnostic methodologies to detect stator inter-turn faults, demagnetization faults and eccentricity faults in the modular electric generator.
The deliverable contributes to the outcomes from WP6, PTO System Design running from M1-M24, and satisfies the following objectives:
The primary objective is to increase reliability and availability while reducing unplanned PTO outages using detailed condition monitoring and scheduled preventative maintenance focusing on the generator and the magnetic gearbox;
Critical conditions such as the stator inter-turn faults, demagnetization and eccentricity will be studied and reliable diagnostic approaches will be developed aiming for fault severity sensitivity and fault identification.
