METHOD OF DETERMINING EFFICIENCY DURING IMPLEMENTATION OF INSTRUMENTS FOR ACCURATE MEASUREMENT OF SHIP DRAUGHT

Abstract

The article justifies the relevance of improving the accuracy of determining the weight of cargo by draught of a vessel in order to increase the economic efficiency of the operation of ships. The authors propose to install remote draught meters on ships, and offer efficiency calculations for the introduction of devices for measuring the draught of ships and their application in practice. The analysis showed that, using traditional methods of draught determination, there is a very significant measurement error that negatively affects the quality of transportation and the reliability of determining the mass of the cargo. The authors present the methodology for determining the economic efficiency of ship equipment with remote draught meters. On test cases, performed for the conditions of transportation of various cargoes on specific lines, the expected efficiency of using remote precipitation gauges is shown in comparison with traditional methods for determining the ship's draft. According to the results obtained, the payback of the installation of draught meters on ships for low tariff cargoes occurs during five voyages, for more expensive and high tariff cargoes during the first voyage.
