Research on the Measurement of Ship's Tank Capacity Based on the Monte Carlo Method

Focusing on the problems of large workload, long time consumption, and high manual involvement on the current methods of the ship's tank capacity measurement, in this study, a Monte Carlo method is applied to measure the ship's tank capacity. The established method realizes the measurement of the tank capacity by arranging the sensing points, conducting a subsequent Monte Carlo test, and performing the error compensation. The results show that when the Monte Carlo method is used to measure the capacity of the tank, in the case when the lower part of the tank is irregular and the upper part is regular, the absolute error of the measurement result is within +/- 0.1m3, and the relative error convergence value is less than 0.1%. The relationship between the absolute error of the measurement result and the hight before error compensation is presented in a form of a Boltzmann curve.
