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).

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.

This deliverable assesses the operation and maintenance (O&M) benefits of integrating MEGA WAVE PTO technology into three representative wave energy converter configurations, comparing its performance with conventional PTO systems.
The results indicate significant potential to reduce O&M costs, improve energy production and increase device availability through modular components, simplified maintenance and reduced vessel requirements. Simulations show reductions in direct O&M costs of up to 66%, particularly where modularity enables repairs at sea rather than requiring devices to be brought back to port. The findings support further optimisation and validation of the technology to improve the cost-effectiveness of wave energy.
