	Standard Engine Orders
	Any engine order given should be repeated by the person operating the Bridge telegraph(s) and the Officer of the watch should ensure the order is carried out correctly and immediately.
	ORDER MEANING (see note*) Full ahead Maximum manoeuvring engine revolutions for ahead propulsion. Half ahead Revolutions as indicated in ship's orders. Slow Ahead Revolutions as indicated in ship's orders. Dead slow ahead Revolutions as indicated in ship's orders. Stop engine(s) No engine revolutions. Dead slow astern Revolutions as indicated in ship's orders. Slow astern Revolutions as indicated in ship's orders. Half astern Revolutions as indicated in ship's orders. Full astern Revolutions as indicated in ship's orders. Emergency full ahead/astern Revolutions as indicated in ship's orders. Stand by engine Engine Room personnel fully ready to manoeuvre and Bridge manned with personnel to relay engine orders. Finished with engines Movement of engine(s) no longer required.
	In ships fitted with twin propellers, the word 'both' should be added to all orders affecting both shafts, e.g. 'Full ahead both', and 'Slow astern both', except that the words 'Stop all engines' should be used, when appropriate. When required to manoeuvre twin propellers independently, this should be indicated, i.e. 'Full ahead starboard', 'Half astern port', etc. Where bow thrusters are used, the following orders are used:
	ORDER MEANING Bow thrust full (half) to port Ship's head to move to port with power as specified. Bow thrust full (half) to starboard Ship's head to move to starboard with power as specified. Stern thrust full (half) to port Ship's stern to move to port with power as specified. Stern thrust full (half) to starboard Ship's stern to move to starboard with power as specified. Bow (stern) thrust stop No bow (stern) thrust revolutions.
	* Note: For vessels with variable pitch propellers, the meaning of the order would include the combination of pitch and revolutions as indicated in ship's orders.
