Overview

What this project is about

Tank Insight eBDN digitalises the Bunker Delivery Note — a legally required MARPOL compliance document for every fuel delivery at sea. The platform manages the full multi-party eSign workflow between buyer, seller, and surveyor, with version control, third-party transmittal to Fuelboss, and a complete audit trail. Used by Total Energies and other global fuel suppliers for bunkering operations.
