Answer / devanesan
Nothing will happen. at the time of load condition also the
turning gear will be in the ON condition. it is the logic.
at this condition if the JOP gets start also nothing will
happen. only posibility is the shaft vibration may
increase. one more thing is the JOP supply is in the bottom
of the bearing. the minimum oil film also near to that
area. it may breaks the oil film and cause for bearing
failure. it will happen in the worst case.

interlocks provided and the comdition will never occur

and jacking oil oump starts to lift the shaft as due to
reduced speed film lubrication is not proper

Nothing will hapen. it may because of loose connection of
