What is the minimum allowable lube oil temperature when starting Ship's Service Turbo Generators (SSTG's)?

The minimum allowable lube oil temperature when starting Ship's Service Turbo Generators (SSTGs) is 60 degrees Fahrenheit. This temperature is critical because oil viscosity affects the lubrication properties necessary for the operation of the turbo generators. If the lube oil is too cold, it may not provide adequate lubrication during startup, potentially leading to increased wear or damage to the engine components.

Maintaining a minimum temperature ensures that the oil can properly circulate through the system, reducing friction and helping to prevent overheating and failure as the turbo generator comes up to operational speed. Therefore, adhering to this minimum temperature guideline is essential for safe and effective operation.
