Other systems are to be put on line during this time too, such as; Lubricating oil systems. Fuel circulating systems.

  5. Standby to Departure On vessels where the engine is directly coupled to the propeller, you need to contact the bridge and request permission to turn the engine.After that, all the indicator cocks are to be opened.
