The invention relates to a method for supplying natural gas to a wharf boat. The method comprises the steps of determining the maximum water level on the surface of a river and the farthest drifting distance from the wharf boat to a river bank in a flood season, mounting a pressure-regulating measuring cabinet at a site, higher than the maximum water level, of the river bank, regulating medium-pressure gas to be low-pressure fuel gas required by the wharf boat, and supplying fuel gas to the wharf boat through a fuel gas control device and a special metal gas supply flexible tube for the wharf boat. The special metal gas supply flexible tube for the wharf boat has the advantages that a tube body can be tightly combined, and the special metal gas supply flexible tube is flexible to use and low in pressure deformation and has circumnutation resistance, so that the problem that a common conveying steel tube cannot be bent is solved, and meanwhile, the disadvantages that a traditional conveying flexible tube is insufficient in gas supply quantity and poor in pressure resistance are overcome. Besides, urgent disconnecting devices are respectively mounted at two ends of the special metal gas supply flexible tube for the wharf boat, so that valves can be rapidly closed by the urgent disconnecting device no matter which end of the special metal gas supply flexible tube for the wharf boat is accidentally snapped in the flood season or when the wharf boat is impacted, and the safety loopholes such as fire disaster and explosion caused by the leakage of natural gas can be prevented.
