INTERNATIONAL CODE OF SIGNALS (ICS)
The International Code of Signals is a standardized communication system used by ships worldwide to exchange important information regardless of language barriers. It combines signal flags, Morse code, and the phonetic alphabet to ensure clear and effective maritime communication.
Key components:
• Signal Flags – Visual communication between vessels and shore stations
• Morse Code – Communication using dots and dashes via light, sound, or radio
• Phonetic Alphabet – Standardized pronunciation of letters over radio transmissions
Examples:
• Alfa (A) – “I have a diver down; keep well clear at slow speed.”
• Bravo (B) – “I am taking in, discharging, or carrying dangerous goods.”
• Hotel (H) – “I have a pilot on board.”
• Oscar (O) – “Man overboard.”
• Quebec (Q) – “My vessel is healthy and I request free pratique.”
Why it matters:
• Eliminates language barriers at sea
• Enhances navigational safety
• Supports emergency communication
• Standardizes ship-to-ship and ship-to-shore messages
• Complies with SOLAS requirements and international maritime regulations
Every seafarer should be familiar with the phonetic alphabet, common signal flags, and their meanings to ensure safe and efficient operations.
