- Underwater operations
- Divers or remotely operated vehicles are working below a vessel that cannot easily move out of the way.
- Until further notice
- The operation or danger has no scheduled end; the warning stays in force until a later message cancels it.
- Cable operations
- A ship is laying, burying or repairing a submarine cable, usually along a stated route.
- Track line joining
- Introduces a route through a series of positions — a cable route, a tow's track or a survey line.

- Keep well clear — or, when a distance is given ("TWO MILE BERTH REQUESTED"), at least that far away.
- Cancellation reference
