Device, program and recording medium for supporting analysis of fuel consumption in voyage of ship

A non-transitory computer readable medium that stores a program, the program including instructions that are executed by a computer to perform:

• a process for acquiring, for a voyage of a ship including mooring at one or more relay ports between a departure port and destination port, data indicating a projected travel time between ports, a projected mooring time at a relay port, projected fuel consumption which is fuel consumption required for travel between ports, and a distance between ports, the process including receiving data transmitted from a ship, the data including an actual travel time between ports, an actual mooring time at a relay port, and an actual fuel consumption required for travel between ports according to a speed of the ship, wherein the projected fuel consumption is calculated based on the projected travel time, the distance between the ports, the fuel consumption according to speed, and a speed based on anticipated weather or marine conditions in one or more sea areas between the departure port and the destination port;
• a process for generating time difference data, the time difference data including a time difference between the projected travel time and the actual travel time and a difference between the projected mooring time and the actual mooring time based on data acquired in the process for acquiring;
• a process for generating fuel consumption difference data indicating a difference between the projected fuel consumption data and the actual fuel consumption data based on the data acquired in the process for acquiring;
• and
• a process for outputting to the ship data indicated by the time difference data and the fuel consumption difference data, the output including a first graph indicating an increase or decrease in the actual mooring time at each of the ports with respect to a reference value, a second graph indicating an amount of a delay in a time of departure from each of the ports, and a third graph indicating an amount of a delay in a time of arrival at each of the ports.

A computer-readable recording medium that continuously records and stores a program, the program including instructions that are executed by a computer to perform:

• a process for acquiring, for a voyage of a ship including mooring at one or more relay ports between a departure port and destination port, data indicating a projected travel time between ports, a projected mooring time at a relay port, projected fuel consumption which is fuel consumption required for travel between ports, and a distance between ports, the process including receiving data transmitted from a ship, the data including an actual travel time between ports, an actual mooring time at a relay port, and an actual fuel consumption required for travel between ports according to a speed of the ship, wherein the projected fuel consumption is calculated based on the projected travel time, the distance between the ports, the fuel consumption according to speed, and a speed based on anticipated weather or marine conditions in one or more sea areas between the departure port and the destination port;
• a process for generating time difference data, the time difference data including a time difference between the projected travel time and the actual travel time and a difference between the projected mooring time and the actual mooring time based on data acquired in the process for acquiring;
• a process for generating fuel consumption difference data indicating a difference between the projected fuel consumption data and the actual fuel consumption data based on the data acquired in the process for acquiring;
• and
• a process for outputting to the ship data indicated by the time difference data and the fuel consumption difference data, the output including a first graph indicating an increase or decrease in the actual mooring time at each of the ports with respect to a reference value, a second graph indicating an amount of a delay in a time of departure from each of the ports, and a third graph indicating an amount of a delay in a time of arrival at each of the ports.
