Live Innovation Opportunities

There are a number of programmes identifying the key technology innovation challenges faced by the offshore renewables industry. Solving these challenges will help drive down the cost of offshore renewable energy, with positive effects for the industry and UK economy. Visit our Live Innovation Opportunities page to find out if your technology has the answer.

Innovation Challenges

Subsea Cable Fault Detection


Fast, effective fault detection in subsea array cables can reduce repair times and therefore improve availability of offshore wind farms. IAC fault detection in offshore wind farms can take several forms ranging from manual switching to active systems utilising voltage detectors and directional fault indicators (plus associated CT/VTs). However, manual detection can be slow, inaccurate and repeatedly exposes wind farm equipment to significant fault currents. Conversely, the “belt and braces” approach can be costly, inflexible and requires significant hardware within the turbine transition pieces or tower bases where space is limited.


Develop a fault detection system for subsea cables enabling the diagnosis of fault type and fault location throughout the cable’s operational life.

Deployment Timescales

Such systems are currently in development. We would expect a prototype to be deployed offshore within the next 12 – 18 months.

Operating Conditions

Offshore – passive hardware would be installed in offshore turbine transition pieces.

Fast, effective fault location in subsea array cables can reduce repair times and improve the availability of offshore wind farms.


For the first time, the Offshore Wind Innovation Competition enables innovative SMEs working in the offshore renewables sector to prove their technology and connect them with investors and potential clients. Successful companies will be able to access ORE Catapult’s world-leading market knowledge and testing and validation facilities to de-risk their technology, as well as pitch their ideas to investment group Green Angel Syndicate and wind farm Owner/Operator ScottishPower Renewables.

The new programme follows a successful trial that saw Bristol-based surveying firm, Rovco, test and validate their innovative new technology at the Catapult’s National Renewable Energy Centre before attracting £160,000 investment from Green Angel Syndicate.

Do you have a potential solution?

The Offshore Wind Innovation Competition could put your technology in front of investors and potential customers.
