On Automatic Weight Measurement in Acceleration Disturbances on Ships

Abstract

In marine development and harbor construction works, it is becoming important to directly produce high-grade raw concrete on ships to shorten the construction periods.
This paper proposes an automatic measurement system which accurately measures the weight (time-variant) of the raw materials on the ships. That is, the measurement system which automatically compensates the indication by load sensors through on-line estimation of the heaving and rolling of ships which act as disturbances in measuring the weight of the raw materials.
