Title:
APPARATUS AND PROGRAM FOR CHECKING RELIABILITY OF DATA INDICATING AMOUNT OF FUEL OIL CONSUMED IN SHIP
Document Type and Number:
Japanese Patent JP2018069790
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a means for ensuring reliability of data indicating an amount of fuel oil consumed in a ship.SOLUTION: The fuel oil evaluation device 1 compares flow rate of fuel oil flowing through an oil supply pipe 93 calculated based on the measurement result of a flowmeter 2 and a decrease amount of the fuel oil stored in a fuel oil tank 92 calculated based on a measurement result of a liquid level meter 3, every time a predetermined time elapses, and the fuel oil evaluation device 1 determines the presence/absence of a mismatch between the measurement value of the flowmeter 2 and the measurement value of the liquid level gauge 3, depending on the result of the comparison. When detecting a mismatch between the measured values, the fuel oil evaluation device 1 notifies the user to that effect.SELECTED DRAWING: Figure 1
