PURPOSE: A fuel-gas supply device of a ship with an LNG storage tank is provided to reduce the amount of combusted boil-off gas since the generation of the boil-off gas is controlled. CONSTITUTION: A fuel-gas supply device(100) of a ship with an LNG storage tank comprises a discharge unit(110), a re-condenser(120), a fuel supply unit(130) and a spraying unit(140). The discharge unit discharges LNG and boil-off gas from an LNG storage tank(210). The re-condenser condenses the LNG and the boil-off gas, which has been discharged from the discharge unit. The fuel supply unit supplies LNG, which has been condensed by re-condenser, to a propeller(220) as fuel gas. The spraying unit collects the condensed LNG and sprays it into the LNG storage tank. The discharge unit comprises a first discharge line(111), a discharge pump(112), a second discharge line(113) and a compressor(114).
