Which item is included as an in-port watch organization requirement?

• A. Cold iron
• B. Main propulsion shutdown
• C. On-deck watch
• D. Engine room ventilations check

Answer: (A)

In-port watch organization centers on keeping the ship safely powered while alongside without running the main propulsion. This is accomplished by using shore power, a practice often called cold iron. Connecting to the shore electrical supply lets essential systems—lighting, communications, pumps, and ventilation—run off outside power while the ship’s engines and boilers stay shut down. That reduces noise, fuel use, and emissions and simplifies safety management in the harbor. The other options describe routine duties or actions that aren’t the defining feature of in-port power management, whereas cold iron specifically embodies the shore-power arrangement used during in-port watch.
