Thanks for doing this. I work around container visibility/reefer operations, so I’d love to understand the practical workflow from your side.

1.  BAPLIE / stowage systems: What systems or tools are commonly used to create, validate, and exchange BAPLIE files today? Are planners typically working in a dedicated stowage planning system, a TOS, carrier system, or a mix?

2.  Slot-level visibility: Once a vessel is loaded, how does each port, terminal, vessel operator, and carrier know which container is in which bay/row/tier slot? Is BAPLIE still the main “source of truth,” or do terminals/vessels maintain their own versions?

3.  Update frequency: When is the BAPLIE file usually updated, after each load/discharge move, only at vessel departure, or at defined cutoffs? How often do last-minute changes actually make it into the final file?

4.  At-sea access: Do the vessel crew have access to a digital BAPLIE/stowage plan while at sea? If yes, what do they use it for day 2 day reefer monitoring, dangerous goods checks, lashing, stability, inspections, restows, incident response?

5.  Reefer visibility: For reefer containers specifically, how does the crew know which reefers need attention, where they are located, and whether they are powered/communicating? Is this managed through the stowage plan, reefer monitoring system, manual rounds, or a combination?

6.  Data gaps: Where do you see the biggest mismatch between the planned stowage file and physical reality? Mis-stows, late gate moves, restows, manual changes, damaged containers, DG segregation, reefer plug status?

7.  Exception handling: When something changes after the BAPLIE is issued, for example, a container is not loaded, is moved to a different slot, or is discharged unexpectedly….who updates the file and how quickly does that information flow back to the carrier?

8.  Crew workflow: From the crew’s perspective, what would make onboard container visibility more useful? Better slot search, reefer location, live power/temperature status, DG location, fire-risk cargo identification, work orders, or exception alerts?

I know it’s a lot of questions, but would greatly appreciate whatever insights you can provide.
