Communication with the
person in charge of vessel operations.F--Only in an emergency. Anchoring will be avoided in a no anchoring area except in the case of immediate danger
to the ship or persons on board.N--Not permitted.P--Transit is permitted when the vessel is not in the immediate area of a tanker, and when cleared by the vessel
traffic supervisor.R--Permitted only if determined that operation does not create unacceptable risk to personnel safety and
security and operation. For transiting foreign-flag vessels, the requirement for clearance to enter the area
to be avoided and no anchoring area is advisory in nature, but mandatory for an anchorage area established
within 12 nautical miles.
