Stowage plan

A stowage plan is the diagram fixing where every container or cargo unit sits aboard a vessel, assigning each box a bay, row, and tier address under the ISO 9711 / cellular numbering scheme. Planners build it from the load list and discharge sequence to keep the ship within its trim, stability, and stack-weight limits, group cargo by discharge port to minimize restows, and segregate dangerous goods to IMDG rules. The electronic form is the BAPLIE message (Bay Plan / stowage plan occupied and empty locations) in UN/EDIFACT, exchanged between line, terminal, and the next port. The terminal operating system reads it to drive crane and yard sequencing.
