With the closure of a ship journey with multiple port loading/unloading activities, the operation department schedules the fueling planning. When the ship consumes 100 tonnes per day in an average 300$/ton price and the oil prices differ significantly from port to port, it is obvious that a good schedule can lead to economic benefits.
