What does the term 'Pan Pan' signify in maritime communication?

The term 'Pan Pan' is a standard distress signal used in maritime communication that indicates a very urgent message concerning safety, but it is less serious than a distress call indicated by 'Mayday.' When a vessel sends out a 'Pan Pan' message, it means that there is a situation requiring immediate assistance, such as a mechanical failure, a person overboard, or the presence of a navigational hazard, but there is no immediate danger to life or vessel as would be the case with a 'Mayday' call.

This term is recognized internationally and is essential for ensuring effective communication in emergency situations, differentiating between varying degrees of urgency. Understanding this classification helps mariners prioritize responses appropriately and comprehend the level of urgency communicated by other vessels, thereby enhancing safety at sea.
