On the way to Antwerp. One of the largest containervessels in the world with a lenght of 398m and a width of 56m. At max. speed of approx 22 nautical miles per hour it uses some 170.000 l of heavy fuel per day.
This may look like a lot, but translated to fuelconsumption per ton of cargo it is very low. The ratio of fuelconsumption per ton of cargo transported compared with airfreight is 130 (airfreight by jumbojet) to 1 (edith maersk).
