Numerical simulation analysis of oil heating process of oil tanker in arctic route

In recent years,with the opening of Arctic routes, the cargo oil heating technology of Arctic routes has become a growing concern. In the transportation process of cargo oil tankers,because the cargo oil has high viscosity,it needs to be heated in advance in order to prevent the oil products from cooling below the freezing point under the influence of external conditions,which will lead to the change of oil quality and the difficulty of discharge. However, excessive heating will lead to increased energy consumption and fuel waste,increased ship operating costs and increased marine environmental pollution. In this paper, COMSOL software is used to simulate the difference between cargo oil heating in Arctic low temperature environment and cargo oil heating at room temperature,and the most economical and energy saving heating method is found to reduce marine environmental pollution.
