Provided is an offshore facility for producing a liquefied natural gas using an associated gas. The offshore facility according to an embodiment of the resent invention includes a crude oil production offshore facility having a crude oil processing device for refining crude oil collected from a subsea well to produce oil, and a gas reinjection device for compressing an associated gas separated in crude oil refining process to be reinjected into a reservoir, and a liquefied natural gas production offshore facility supplied with a feed gas including at least a part of the associated gas from the crude oil production offshore facility, and processing and liquefying the feed gas to generate a liquefied natural gas. The crude oil production offshore facility includes a feed gas supply unit for recovering a back-flow gas formed when an injection gas compressed by the gas reinjection device flows backward and generating the feed gas by using the back-flow gas. According to an embodiment of the present invention, the offshore facility in which the gas (injection gas) compressing the associated gas is reinjected to a reservoir is configured such that the gas reinjected to the reservoir may be recovered by flowing backward, and the recovered back-flow gas is used produce the liquefied natural gas, so that the productivity of the liquefied natural gas using the associated gas may be improved.
