Abstract: The present invention relates to flowing LNG revaporization equipment. The flowing LNG revaporization equipment comprises an LNG storage tank (10) and an LNG revaporizer (20), wherein the flowing LNG revaporization equipment further comprises power generation equipment which is capable of generating power, as well as generating gas through the LNG revaporizer (20). Accordingly, since a gas turbine generator which is a power generating equipment to generate power is additionally included in the revaporization equipment to revaporize LNG, more specifically, it is possible to supply gas and electricity at the same time. Also, since it is possible to drive the gas turbine generator with gas generated from the revaporization equipment, a compressor for processing gas is removed from the gas turbine generator, so that it is possible to reduce the cost for installing the gas turbine generator. In addition, after vapor is generated using exhaust gas which is generated from the gas turbine generator, the generated gas can be used as the driving power for the LNG revaporizer and a steam turbine generator which is additionally included to generate electricity. Thus, it is possible to minimize the energy required for the entire equipment according to waste heat recovery, so that it is possible to reduce the cost and to prevent oceanic pollution through the usage of waste heat.
