While looking for ways to improve the marine fuel delivery process, we observed a weak link in the chain: the paper-based Bunker Delivery Note (BDN).  Nearly all BDN's are still completed by hand with pen, paper and a calculator.  If Mass Flow Meters (MFM) are not used, manual volume calculations are based on outdated tables.  This increases the margin for error and causes delays in document delivery, slowing down your and your customer's business.

Problems with Paper BDN's

Vortex's field research team concluded that there was significant room for improvement and created a digital alternative to hand-written BDN's and ship safety forms.  After research and testing in the marketplace, we launched the Digital Bunker™ solution -- Electronic Bunker Delivery Notes (E-BDN™). This SaaS application, offered on a monthly subscription basis, saves you time and money by improving the operational efficiency of your bunker deliveries.​ 

Repetitive printing costs of BDN, Safety and Compliance forms

Illegible or incomplete forms are a liability in a court of law

Archival storage requires constant scanning and administration

Sharing forms is slow and must take place back at the office after scanning

Paper-based forms provide no analytics of content

Lost or damaged forms put a company at risk for claims

Solved with Digital Bunker

 Why Digital Bunker?

Additionally, MFM does not provide a complete BDN, only a printout from the meter. Vortex's Digital Bunker™ solution captures meter tickets and provides for Ship Stamps, GPS tagging and signatures on an Electronic Bunker Delivery Note (E-BDN™).

 challenging the status quo

The Digital Bunker™ E-BDN™/E-BDR™ from Vortex Development Group is legally compliant and enforceable and is a preferred method for BDN/BDR record keeping, proof and authentication.
