From MFM ticket to Bunker Delivery Note — offline, always correct
The successor to a macro-driven Excel workbook. Entering one delivery produces the complete package: the legal Bunker Delivery Note (BDN), sample labels, product specifications, safety data sheets and the port-specific safety checklist — all from that single entry, without anyone stepping through a template by hand again.
BDN numbers are validated live against the current block and against what has already been used — a duplicate or out-of-range number is flagged immediately, before it becomes a compliance problem. The BGD customs write-off administration follows the same principle: no bunker cargo can be administratively on board without a covering BGD, and the balance can never drop below zero.
Fully offline: a single SQLite file on the barge PC is the only store, no network required. An automatic MFM continuity check and Qmin/MMQ warning follow ISO 22192. Updates and template packs are picked up by themselves the moment there is a connection; the rest of the time everything just keeps working.

What's new
Recent improvements, newest first.
-
Dates and times in the BGD workbook always readable
August 2026On the deeper rows of rubriek 10, a date or time could appear as a raw number instead of a readable format; that is now fixed across the whole grid. The delivery's time is also carried automatically into a BGD write-off, not just the date.
-
More reliable printing through the regular PDF viewer
August 2026The buttons for the BDN, the complete bundle, individual documents and the sample receipt now open the document in the regular Windows/Linux PDF viewer instead of a print window that could hang or silently switch to double-sided printing.
-
Managed BGD workbooks fully editable, MRN no longer lost
August 2026A manual correction made by the office on a BGD workbook can now be adopted directly as the new source of truth. Newly built workbooks are now fully editable (the customs template itself used to lock them almost shut), and the legal MRN number no longer disappears in a number of edge cases.
-
Emergency reset for the BGD administration, readable filenames
August 2026A BGD administration that no longer matches the folders on the barge can now be reset in one step (with an automatic backup taken first). Generated workbooks get a readable filename (sequence number, product, GN code) instead of just a bare document code.
-
MFM automation per ISO 22192
August 2026Automatic check that a delivery's starting totalizer reading matches the previous delivery's end reading on the same flow meter (Annex O), plus a warning whenever a quantity falls below the instrument's MMQ/Qmin — with a direct link to the Bunker Requisition Form.
For skippers who want to close out a bunker delivery without an Excel macro that once went wrong, and for offices who want every BDN number and every customs write-off to be correct before it becomes a problem.
