Reading this warning
- Underwater operations
- Divers or remotely operated vehicles are working below a vessel that cannot easily move out of the way.

- Wide berth requested
- Keep well clear — or, when a distance is given ("TWO MILE BERTH REQUESTED"), at least that far away.
- CANCEL THIS MSG
- The warning's own expiry: a line telling the reader when the message cancels itself.
