Highlights
•Reliability is a key driver of the cost of energy for tidal turbines.
•Reliability prediction is challenging due to scarcity of relevant failure data.
•The proposed model estimates failure rates using component design parameters.
•The key design drivers for pitch system reliability are determined.
•The simulated failure rate is found to be lower than comparable wind turbines.
