The IBC rule precursor is "ship construction and equipment rules for bulk transport of hazardous chemicals" (BCH rules). The chemical tanker is cumbersome to operate and is full of risks. The method has the advantages that the influence factors of the tank washing of the chemical ship are explored, the tank washing safety of the chemical ship is evaluated, the risk of the chemical ship during tank washing is prevented, the intelligent management level of the chemical ship is improved, the personal and property safety during tank washing is ensured, and the research work is significant.

Most of the current known jet flow cleaning calculation models are based on the empirical correlation between adjustable operation parameters and cleaning results, and the tank cleaning process has the joint participation of gas, tank cleaning water and chemicals and belongs to a multiphase flow process. Establishing a model, introducing the model into Fluent software, selecting independent variable parameters, performing finite element calculation, acquiring the removal rate of chemicals in a cabin wall area after a wall hanging process and a flushing process so as to explore the cabin washing effect and the cabin washing safety, and verifying the correctness and the accuracy of the multiphase flow dissolution calculation model by combining an experimental result; and (4) acquiring the volume fraction of the gaseous chemical in the cabin, and comparing the volume fraction with the lower explosion limit of the gas to ensure the safety of the cabin washing process.

The research of these patents and articles has focused on the use of a method or system for rinsing residual chemicals in some chambers, which can be better observed after rinsing. However, for different types of chemicals, as the cleaning mechanism is not clear, the rotating position and speed of the tank cleaning machine are uncertain, and the tank cleaning operation is considered to be finished if and only if all conditions of the ship cargo tank meet the requirement of loading the next type of chemicals.
