Failed ECA Entry: $100K Fine for Incomplete Fuel Switch
They calculated 90 minutes for fuel system changeover. At 60 minutes, Port State Control boarded. Sulphur content still showed 0.35%. The fine: $100,000.
Failed ECA Entry: $100K Fine for Incomplete Fuel Switch
They calculated 90 minutes for complete fuel system changeover.
At 60 minutes, Port State Control boarded.
Sulphur content still showed 0.35%—3.5x the ECA limit.
Fine: $100,000 + 5-day detention.
The Incident
Vessel: MV Eastern Promise
ECA: North Sea (0.10% sulphur limit)
Switch: HFO (0.50% S) to MDO (0.10% S)
Fuel System Volume: 18 MT
The Calculation Error:
Why They Failed
Mistake 1: Used Average Calculations
They used a standard "5 minutes per MT" rule of thumb.
Reality: Their system had dead legs, low-flow areas, and a leaking return line that wasn't accounted for.
Mistake 2: No Verification Testing
During changeover, nobody tested fuel sulphur content.
A simple hand-held sulphur tester would have revealed the problem at 70 minutes.
Mistake 3: No Buffer Built In
Started the switch exactly 90 minutes before ECA entry.
No buffer for:
Mistake 4: Poor Documentation
Fuel oil switch log wasn't being maintained in real-time.
