VLSFO - Well-to-Wake
Very Low Sulphur Fuel Oil (≤ 0.50 % S) WtW GHG. Same Cf as HFO; LCV slightly higher from the paraffinic blendstock.
Tank-to-wake CO₂
3,114.00t
From Cf per MEPC.364(79)
Energy content
40,500GJ
LCV 40.5 MJ/kg
Well-to-wake GHG
3,713.9t CO₂e
91.7 gCO₂e/MJ WtW
Method
TTW CO₂ (t) = mass × Cf Energy (MJ) = mass (kg) × LCV (MJ/kg) WtW (t CO₂e) = Energy (MJ) × WtW factor (g/MJ) / 1e6
WtW factors include upstream extraction, processing, transport, plus tank-to-wake combustion and relevant CH₄/N₂O. FuelEU Maritime Annex II publishes the authoritative defaults.
