The present invention relates to a marine liquefied natural gas regasification system. The present invention regasifies liquefied natural gas using seawater as a heat source to produce natural gas. The seawater supplies heat to working fluid which provides heat to regasify the liquefied natural gas. If additional heat is required, the regasification system supplementarily uses a heat source used by an equipment installed in the regasification system. Only a first heat exchanger (20) exchanges heat with the seawater to prevent the regasification system from deteriorating by the influence of seawater, and heat of the supplemental heat source is directly transferred to the working fluid. Moreover, in order to more efficiently use energy of the supplemental heat source, a temperature of the working fluid flowing into a second heat exchanger (30) from the first heat exchanger (20) is detected, and a control unit (38) adjusts an amount of the supplemental heat source into the second heat exchanger (30) based on the temperature of the working fluid. As the amount of the supplemental heat source is adjusted by a temperature adjustment valve (36), which is a proportional control valve, only a required amount of the supplemental heat source can be supplied to transfer the working fluid of a constant temperature to a gasifier (10) to gasify the liquefied natural gas more uniformly and reliably. |
