Hello,
We have nuovo pignon 5002c turbine. During major shutdown in facility where I work, after 6 hours an operator alarm us about problem in the turbine ratchet. We discover that ratchet didn't run for entire 6 hours. And after intervention in it work for just 1 hour (the sequance of cool down is 8 hours) .
The question is there is anybody deal with this situation or heard about bending of HP rotor? Because we are afraid run the turbine (even in crank), and we are very scared about losing the turbine.
