The $75K Mistake: How a Junior Buyer Lost a Quantity Dispute

Six months into his first bunker buying role, James made a $75,000 mistake.

He signed the Bunker Delivery Note without checking the meter readings against tank soundings.

When the discrepancy surfaced three weeks later, he had no case.

The Incident

Vessel: MV Pacific Voyager

Location: Singapore

Fuel: 500 MT VLSFO at $600/MT

The Numbers:

  • BDN quantity: 500 MT
  • Vessel's calculated quantity: 487.5 MT
  • Discrepancy: 12.5 MT
  • **Value at risk: $7,500**
  • But James had signed the BDN noting "500 MT delivered."

    Without documentation of the discrepancy, the supplier refused any adjustment.

    Why He Lost the Dispute

    Mistake 1: No Pre-Bunkering Documentation

    James didn't record initial tank soundings. Without baseline measurements, he couldn't prove the actual quantity received.

    Mistake 2: Signed Without Verification

    He signed the BDN immediately after delivery, before reconciling meter readings with tank soundings.

    Once signed, you've accepted the quantity as correct.

    Mistake 3: No Evidence During Delivery

    He didn't document periodic meter readings, temperatures, or flow rates during bunkering.

    Mistake 4: Delayed Response

    He waited 3 weeks to raise the issue. By then, the supplier argued fuel had been consumed and verification was impossible.

    The $75K Total Cost

  • Lost fuel value: $7,500
  • Legal fees: $8,500
  • Off-hire during dispute: $12,000
  • Reputation damage: Priceless (lost bonus)
  • Management's confidence in him: Shaken
  • What He Should Have Done

    Before Bunkering

  • Document initial tank soundings
  • Calculate expected delivery quantity
  • Note temperature and density requirements
  • Agree on measurement method with supplier
  • During Bunkering

  • Record meter readings every 30 minutes
  • Monitor temperature continuously
  • Watch for air in delivery lines
  • Document any anomalies immediately
  • Before Signing BDN

  • Reconcile meter vs. tank calculations
  • Note any discrepancies on the BDN
  • Request supplier acknowledgment
  • Don't sign if difference exceeds 0.3%
  • After Signing

  • Retain all documentation for 90 days minimum
  • Take photos of meters and gauges
  • Keep sealed fuel samples
  • File the signed BDN with supporting data
  • The Real Cost

    James kept his job, but:

  • He was moved from buyer to assistant
  • His bonus was withheld that quarter
  • He's now on a performance improvement plan
  • All from avoidable quantity dispute errors.

    Key Takeaway

    Documentation is your only defense in quantity disputes.

    Sign nothing until you've verified. Document everything during delivery. Act immediately on discrepancies.

    Otherwise, you're accepting whatever quantity the supplier claims—regardless of reality.
