The invention discloses an inert gas protection integrated system for a methanol dual-fuel liquid cargo ship. The system comprises a cargo oil inert gas system and a methanol inert gas system, the cargo oil inert gas system comprises an auxiliary boiler, an IGG inert gas system, a deck water seal and a cargo oil tank, the auxiliary boiler is sequentially connected with a pneumatic control valve and an expansion joint to form an auxiliary boiler gas inlet pipeline, the auxiliary boiler gas inlet pipeline is connected into the IGG inert gas system, and the IGG inert gas system is sequentially connected with the deck water seal and a cargo oil tank gas inlet header pipe. The cargo oil tank gas inlet header pipe is communicated with a cargo oil tank through a cargo oil tank gas inlet branch pipe, the methanol inert gas system comprises a methanol inert gas inlet branch pipe, the methanol inert gas inlet branch pipe is communicated with the cargo oil tank gas inlet header pipe, and the methanol inert gas inlet branch pipe is sequentially communicated with a nitrogen compressor, a dryer and a nitrogen cylinder; the nitrogen cylinder is connected to the methanol filling system, the methanol cabin, the main methanol double-wall pipe, the methanol lightering system, the main methanol daily system, the main machine methanol daily system and the boiler methanol daily system through distribution pipelines. The system is high in exhaust utilization rate and low in energy consumption.
