Based on the vent mast of LNG ship type, this paper simulates the concentration distribution of ammonia when it is discharged through the vent mast with the maximum discharge in three cases: windless weather, bulk carrier and container ship, and explores the optimal safety range of the vent mast and whether it can meet the relevant requirements of Classification Society. The results show that when there is no wind, when the ship is docked or bunkered, the safe distance radius of the vent mast is at least 30m. On the premise that the distance from the ventilating mast to the stern is 150m, the bulk carrier sails at a speed of 25km/h, and the dangerous space should be above the range of 40m×20m×150m (width×height×length). Large container ships sail at a speed of 45km/h, and the dangerous space should be more than 30m×20m×150m (width×height×length). In the event of large-scale leakage or discharge of ammonia gas, crew members need to wear protective equipment when entering this area.
