Which system is used for ship-wide voice communications?

• A. Integrated Voice Communication System
• B. Sound Powered Telephone
• C. Ships Information Book
• D. Closure Log

Answer: (A)

Integrated Voice Communication System is the ship’s central intercom network, tying together all spaces and allowing broadcast messages as well as direct calls between stations. It’s designed to reach every deck and compartment, so orders, safety alerts, and muster calls can be heard by everyone at once. Sound-powered telephones are a local, power-free means of voice communication and don’t provide full ship-wide coverage on their own. The Ships Information Book and the Closure Log are administrative tools, not communication systems. So the Integrated Voice Communication System is the correct choice for ship-wide voice communications.
