Background
Crude oil transportation mainly depends on a large oil tanker, but generally cannot navigate in Yangtze river and inland river due to large draught volume, most oil refineries are not at sea, so the large oil tanker cannot directly arrive, and most oil refineries finish final connection transportation by a barge of a tugboat fleet. Because the barge is a powerless ship without a heat source, most of production places have high crude oil viscosity and cannot be transported in a flowing mode at normal temperature, before unloading, the crude oil must be heated by steam at a wharf, so that the temperature and the viscosity of the crude oil are increased to be more than a critical value convenient for the crude oil to flow, and then unloading can be carried out. Taking a conventional 5000-ton barge as an example, the initial temperature of crude oil in a cabin and the temperature of river water are both 15 ℃, and the minimum flow critical value of crude oil heated to 45 ℃ needs 12 hours. This means that the barge occupies the wharf for 12 hours, the utilization rate of the barge is reduced, and the extra energy cost of the wharf is at least 2.5 ten thousand yuan. In order to improve the unloading efficiency of crude oil, an oil-fired boiler can be arranged on the barge, and the oil-fired boiler is used for producing steam to heat the heat-preservation crude oil during transportation. The two methods increase the transportation cost of the crude oil transportation tug fleet and seriously affect the economic benefit of the crude oil transportation tug fleet.
