A new Emergency Safety Device (ESD) based on a PLC module that can start and stop a modified dual-fuel diesel engine in automatically has been created. When fitted to a modified dual fuel engine, the laboratory scaled PLC module has been tested and found to perform well in any programmable emergency circumstance. Because the modified engine's compression ratio has been increased, the risk of hazards has increased as well. When any predefined dangers are recognized, the ESD logical code can automatically control the functioning of the fuel system to provide uninterrupted fuel delivery, but it can also halt the fuel supply, including gas and diesel fuel. Over-pressure, over-temperature, flow rate, rpm, and gas leakages are all potential hazards. To identify those potential hazards, then scoring method is used to model and simulate them quantitatively. The simulation data is used as input data for Arduino Source Code, which is used to process logical acts in the marine engine operation. Finally, the safety level is assessed using a safety standard approach such as the SHEL Method. The results of the works show that ESD eligible to control the operation of gas fuel system and it is considerable to be applied for gas-powered ship.
