Abstract
A submarine gas-leakage monitoring system for long-term detection of gas and a method of operating the same are disclosed. The submarine gas-leakage monitoring system includes: a buoy equipped with a satellite communication unit to transmit acquired data to a satellite or to receive a command for activation or inactivation of a first submarine sensor from the satellite when the buoy is raised to float on the seawater surface; a seabed observation unit located close to a seabed, the seabed observation unit acquiring and storing information about gas leakage from the seabed and controlling the buoy such that the buoy is raised or lowered; and a signal cable equipped with the first submarine sensor that detects migration or diffusion of leaked gas and connected between the buoy and the seabed observation unit to allow a signal transmission between the buoy and the seabed observation unit.
