The present invention relates to a hood room ventilation structure of a liquefied gas carrier. The structure includes: a hood room including a gas valve unit to control supply pressure of gas fuel by being connected to a gas fuel supply system of an engine; a taking air pipe supplying outer air to the hood room; an exhausting pipe discharging inner air in the hood room to the outside; and a ventilation fan installed on an exhaust pipe. The exhaust pipe is longer than the intake pipe, and the diameter of the intake pipe is bigger than the diameter of the exhaust pipe. Therefore, the sizes of the exhaust and intake pipes, installed in the hood room, and a ventilation condition of the hood room are optimally designated to stably maintain a sound pressure state of the hood room, and thus risk of explosion is removed and system safety is secured. |
