MTOD is the Mean Time to Observable Damage. Here at Sentient Science, we take in your turbines SCADA data, major component exchanges, borescope information, wind loads and sub-component information to help forecast when you should see observable damage in your turbine.
Below is a view of the MTOD for a list of turbines. You can see that if we have knowledge of all your sub-components inside your gearbox (T01), we can give you a specific month that you will see damage. If we don't know all of your sub-components, you will then be provided a range for your MTOD (T03). The more we know inside your gearbox, the better our forecasting can be!
