What is pnr movement in shipping?

PNR movement in shipping refers to the "Pre-Notice of Readiness," which is a notification sent by a ship's captain or agent to inform the port authorities and relevant parties that the vessel is ready to load or discharge cargo. This notice is crucial for scheduling port operations and ensuring that all necessary arrangements are in place for the vessel's arrival. The PNR allows for efficient planning and coordination among shipping lines, port operators, and cargo owners. Timely submission of the PNR can help avoid delays and optimize turnaround times in port operations.
