It is achieved by a dangerous gas monitoring system generated in a vessel comprising a repeater for transmitting to the portable terminal and a signal conversion unit for converting the signal received from the repeater to the operator's portable terminal visually and audibly.

Here, it is preferable that the repeater and the portable terminal communicate by wireless broadband Internet service.

According to the dangerous gas monitoring system generated in the ship according to the present invention, the signal generated from the gas leak detector installed in the dangerous gas generating area or the enclosed space is transmitted to the monitoring unit of the situation room and the signal transmitted to the monitoring unit is a wireless broadband Internet service. By being transmitted to the portable terminal of the field worker via a repeater providing a, the field worker can grasp the situation of the monitoring unit of the situation room in real time, so that it can quickly and accurately perform the response.
