Disclosed are a fuel supply system of engines for a vessel and a fuel supplying method. The fuel supply system for the engines of the vessel, in the fuel supply system of engines for a vessel, wherein the engine includes a first engine and a second engine, includes: a storage tank wherein liquefied natural gas (LNG) is stored; a forcible evaporator receiving the LNG from the storage tank, evaporating the received LNG, and supplying the evaporated LNG to the first engine; and a separator controlling the LNG to be at a methane number required for the first engine by removing heavy hydro carbon (HHC) contained in the LNG evaporated by the forcible evaporator. At least part of the HHC separated by the separator can be supplied to the second engine as fuel. The purpose of the present invention is to suggest a fuel supply system capable of effectively treating the HHC separated from the LNG while supplying the fuel to the engines by effectively controlling the methane number of the LNG.
