Combat Information Center

• Combat Systems Watch Officer (CICWO)– Supervises the combat information

center (CIC)– Ensures that OOD is kept advised of

recommendations for maintaining station and safe navigation.

Combat Information Center

• Tactical Action Officer (TAO)– Assigned by the CO during wartime

steaming or higher threat– Responsible for tactical employment of

ship’s weapons systems and ship defense.

– The CO gives this person direct authorization to fire weapons (without getting his permission, if necessary)

Engineering

• Engineering Officer of the Watch (EOOW)– Responsible for the safe operation of

the ship’s engineering plant.– Keeps the Engineering Log and Bell

Book

Engineering Log

• Daily record of all aspects affecting the engineering plant– Operation of ship’s propulsion and

auxiliary machinery– Any significant change to plant status is

Proper Watch Turnover

• Oncoming watchstander makes a tour of his/her watchstation and reads logs.– EOOW: Propulsion plant– OOD: Various places throughout the ship

(Engineering plant, CIC)• Offgoing watchstander briefs his/her

relief– Events that happened during previous

watch– Upcoming events

Proper Watch Turnover

• Oncoming watchstander makes sure that he/she has full understanding of the situation before relieving the watch.

• (Saluting) “I relieve you, sir.”• (Saluting) “I stand relieved.”• “Attention in the pilot house! This is LT
