The invention discloses a marine engine room ventilation system. The marine engine room ventilation system comprises a fan, a frequency converter, a main loop, a bypass loop, a bypass switch and a control module. The frequency converters operate in the main loop, and the multiple fans and the multiple frequency converters are connected in a one-to-one correspondence mode; the bypass switch is used for controlling the fan to operate in the bypass loop so as to enable the fan to enter a bypass mode; the control module is electrically connected with the frequency converters and the bypass switch, and the control module is used for obtaining an automatic frequency conversion mode setting instruction and controlling the multiple frequency converters to drive the multiple draught fans to operate in sequence based on the automatic frequency conversion mode setting instruction. By the adoption of the scheme, the marine engine room ventilation system is energy-saving and reliable.
