Module 18 - Signals & Communications

PAN-PAN and SECURITE

PAN-PAN is used for urgent situations such as engine failure near a lee shore, a serious but stable medical problem, a lost person not yet known to be in immediate danger, or a vessel disabled but not sinking. It tells others that the situation is serious and may develop.

SECURITE is used to broadcast safety information. Examples include a container adrift, a new obstruction, defective navigation light, severe local weather, or restricted manoeuvrability affecting other traffic. The call normally starts on Channel 16 before moving to a working channel if directed.

Key points

  • PAN-PAN: urgent help or advice needed
  • SECURITE: safety information for other vessels
  • Both are made initially on Channel 16 unless local procedures say otherwise
  • Cancel or update the call when the situation changes
