What are the causes of fatigue failure?

Causes of fatigue failure are:
  1. Engine operating with excessive cylinder pressures
  2. Tie bolt tension incorrect, either too high or low
  3. Jacking bolts over-tensioned on the Sulzer type slow speed engines
  4. Crankshaft alignment poor, either due to local bearing failure or poor chock support, or vessel hull deformation
