Abstract: Practical training in ship fuel oil purifier systems have lots of limitations including poor stability, development difficulties and high maintenance cost. A semi-physical simulation system for marine fuel oil purifier was proposed. According to the real ship control box, a fuel oil purifier control box was designed. A process simulation system was developed to simulate the fuel oil tube and purifier function, which could achieve the working process of purifier system and the phenomenon of fault alarm. The simulation system can reappear the working process of the oil purifier and simulate the fault conditions to improve the students' ability of processing and analysis of the failure.

Key words: marine fuel oil purifier, process simulation system, oil purifier control box, semi-physical simulation
