Apparatus, program and recording medium for managing risk of contamination of ships

摘要

The receiving means 120 receives data indicative of the water temperature, boat speed, and the period during which they are maintained. The index value acquiring unit 123 reads the decreasing amount of the antifouling paint according to the water temperature and the boat speed received by the receiving unit 120 from the storage unit 121. The index value specifying means 124 specifies the decrease amount of the antifouling paint in the period by multiplying the decrease amount read by the index value acquiring means 123 by the time length of the period received by the receiving means 120. The decrease amount specifying means 125 integrates the decrease amount of the antifouling paint specified by the index value specifying means 124 after painting of the antifouling paint. The remaining amount specifying means 126 specifies the coating thickness of the present antifouling paint by subtracting the decrease amount of the antifouling paint accumulated by the decrease amount specifying means 125 from the paint film thickness at the time of painting the antifouling paint.
