HULL FOULING EVALUATION DEVICE AND HULL FOULING EVALUATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a hull fouling evaluation device and a hull fouling evaluation program capable of appropriately evaluating an extent of an impact of hull fouling on hull performance.SOLUTION: A control part of a hull fouling evaluation device functions: as roughness impact coefficient calculation means for calculating a roughness impact coefficient which is a value made dimensionless on the resistance based on the hull fouling of the hull resistance of a vessel, based on data by date and time for each date and time including operation information on the vessel at each of a plurality of dates and times collected from the vessel and the weather and hydrographic information on a vessel sailing sea area at each date and time, by executing a hull fouling evaluation program; and as fouling impact index value calculation means for calculating an average value of all roughness impact coefficients calculated by the roughness impact coefficient calculation means within a period of a predetermined range based on the calculation object date and time, and setting the average value as a fouling impact index value at the calculation object date and time.SELECTED DRAWING: Figure 2
