SMDG SMDG develops and promotes UN/EDIFACT EDI-messages for the Maritime Industry and is an official Global User Group, recognised by the UN/EDIFACT Board. The group produced the standard format for the exchange of ship stowage planning information. Now known as the BAPLIE message, it defines the position of containers in a vessel. Since implementation of the first version of BAPLIE its use has grown rapidly across the world. All carriers and deep-sea container terminals are now dependent on its use for accurate and timely information. Experience has brought refinement and further development with the latest BAPLIE version 3.0 now being introduced.
