crank the shaft

If the oil pump cannot be used in an emergency situation for the steam turbine, can it be manually turned? Will this have an impact on the rotor?
During shutdown or warm-up periods, turn the shaft at intervals; it’s a bit more troublesome to do this manually, but there are no negative effects – the key is not to interrupt the process
Manual turning is available, but the oil station and dry gas seal must not be stopped; shutdown is possible only after the temperature drops
Can the turbine be turned manually without lubricating oil?

Can the turbine be turned manually without lubricating oil?
You mentioned that the lubricating oil pump has stopped – is it still possible to manually turn the shaft? Generally, turbine lubrication oil pumps are driven by motors or small turbines; are yours also motor-driven? Is there a power outage? In emergency situations, during shutdown, the rotor must be turned even in the absence of lubricating oil; otherwise, rotor bending can cause serious problems
