Challenges/Opportunities

Offshore renewable energy systems require maintenance and repair which is challenging in the ocean environment.

Solution

Innovative improvements in sub-systems that raise reliability and performance will reduce maintenance and repair requirements.

Context And Need

All offshore renewable energy systems involves complex equipment in a harsh and inaccessible environment. Offshore wind turbines require frequent visits for scheduled and unscheduled maintenance. Tidal turbines and wave energy devices also have a requirement for maintenance, and the reliability of some trial devices has been lower than planned.

This challenge could be tackled through fundamental improvements in designs, materials and manufacturing, to make sub-systems more reliable and perform better.

Summary

Develop new component solutions with innovative, materials, designs, operating principles to plug gaps in system reliability and to extend or expand device performance.

Impact Potential

New sub-systems that have higher performance and better reliability will reduce the maintenance costs of all types of offshore renewable energy system. This will contribute to continued cost reduction in offshore wind, and help to bring tidal and wave energy into commercial use.

Research Status

Active projects include:

  • FLOTANT (Innovative, low cost, low weight and safe floating wind technology optimized for deep water wind sites): The main objective of FLOTANT is the development of innovative solutions to improve the robustness and cost-efficiency of 10+MW wind turbine generators in deep waters (100-600m). This goal will be achieved through the design and test of specific components, as well as the assessment and optimisation of the construction, installation, operation and decommissioning techniques, in line with state-of-the-art practices and environmental constraints http://flotantproject.eu/


Previous projects include:

  • All Electric Drivetrain for Marine Energy Converters (EDRIVE-MEC)

EDRIVE (EP/N021452/1) aims to tackle a fundamental weakness of current wave energy converters, namely the electro-mechanical Power Take-Off (PTO). EDrive will improve the PTO chain from generator through to grid interface by creating an all-electric solution. This will, in turn, address issues of reliability and maintainability. https://www.edrive.eng.ed.ac.u...
