Stops (i.e. grid issues), downtime (i.e. failures relates to sub‐systems, assemblies and subassemblies)
and fault diagnostics is available for onshore wind turbine and farms collected over the
last twenty years in both the USA and Europe with some further, but sparse offshore data available.
Onshore failure rates and downtime indicates that electrical systems have the highest failure rates
and that gearboxes cause the longest downtime per failure. In addition 75% faults caused 5%
downtime and 25% faults caused 95% downtime. Annually, 1 to 3% of turbines require blade
replacements with spikes in years 1 and 5. About 2% of turbines per year (through 10 years of
operations) require blade replacements; lightning strikes are the most commonly noted cause of
failure. Average gearbox failure rate over 10 years of operations is estimated at 5%, peaked in years
4, 5 and 8. The average generator failure rate is somewhat lower and over 10 years of operations is
estimated at 3.5%, peaking in years 6 and 7.
An accurate understanding and effective management strategy of offshore wind turbine stops,
downtime and fault diagnostics is critical for optimum operation and maintenance so that the
turbine realises its full asset potential. The aim of this project is to fully profile stops, downtime and
fault diagnostics of offshore wind turbines in order to 1) build a comprehensive outage database and
2) design an innovative, proactive rather than reactive mechanical‐power electronic coupled fault
diagnostic tool to ensure a robust long term financial return for investors, owners and operators.
The main language of the programme is English, hence all applicants are required to be proficient in both spoken and written forms of the English language. If not a native speaker, evidence must be provided of IELTS English proficiency or equivalent at level 6.5 or above.
The Bryden Centre PhD Studentships have been funded under the European Union's INTERREG VA Programme.
This project is supported by the European Union’s INTERREG VA Programme, managed by the Special EU Programmes Body (SEUPB).
The studentship covers fees, plus a stipend at the RCUK level, for a total of 36 months (including writing-up).
Funding is available for students worldwide, however non UK/EU students will be liable for the difference between home/EU and international fees.
