BAPLIE

BAPLIE (Bay Plan) is the UN/EDIFACT message used between shipping lines, terminals and ports to communicate the complete stowage plan of a container vessel — every container's slot position (bay/row/tier), weight, hazardous goods status, reefer status, port of discharge and other operational attributes.

BAPLIE is fundamental to terminal operations: stevedores use it to plan discharge sequences and crane allocation; port authorities use it for safety and DG segregation checks; downstream terminals use it to plan their own loading. The message is exchanged at each port call — first as a "stowage as loaded" snapshot, updated en route as containers are loaded/discharged.

The current version, BAPLIE 3.1.1, is published by SMDG (Shipping Message Design Group), the maritime industry's EDI standards body.
