On a cruise ship, many people come together. To prevent all passengers from immediately panicking in the event of a medical emergency or similar situation, the crew uses a kind of secret language.
Panic and Uproar Should Be Avoided
Standing at the railing, looking out at the sea, and enjoying the vacation—and suddenly an announcement like “Man overboard!” comes through! This could potentially cause panic among the passengers. For this reason, there are secret codes that the cruise crew uses to communicate with each other. This is to prevent guests from noticing everything and causing unnecessary commotion. A former cruise ship employee confirms to TRAVELBOOK that such code words do exist. This allows the crew to communicate with each other.
The Secret Codes of the Cruise Ship Crew
To ensure that cruise ship employees can communicate quickly and easily—regardless of the language they speak—there are secret codes. These can vary depending on the cruise line. However, the following words are the most common:
Alpha: When the code word Alpha is announced, it usually indicates a medical emergency. The crew knows what to do upon hearing this announcement.
Bravo: If you hear the secret code Bravo, the cruise ship crew is informed that a fire has broken out on board.
Echo: This code indicates a problem with the ship. It means that the ship is drifting or there could be a collision.
Kilo: This secret code word signals the crew to report to emergency stations to prepare for a possible evacuation.
Oscar: In the event that a passenger goes overboard, there are various code words. One of them is Oscar.
Operation Bright Star: Sadly, but also possible on a cruise, this announcement means there has been a death on board.
30-30: Less dramatic, but still important for the cruise staff, this announcement means the cleaning team should come to clean up a mess.
The code words are based on the spelling aids of the NATO alphabet. This is the international version, while in Germany, the national spelling alphabet is more commonly known, where Anton stands for the letter A, Berta for B, and so on. In the NATO alphabet, A stands for Alpha, B for Bravo, and so on. The reason these codes are used on cruise ships is simple: Crew members usually come from many different nations, and this allows them to communicate most effectively.
