Title:
EVALUATION SYSTEM, EVALUATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/069775
Kind Code:
A1
Abstract:
Provided is an evaluation system comprising a removal means which removes fouling from a surface of a propeller of a vessel, a determination means (412) which determines a fouling degree of the surface of the propeller before the fouling is removed and surface roughness of the propeller after the fouling is removed, and an output means (46) which outputs the fouling degree and the surface roughness.
