The present invention provides a vessel for liquefied hydrogen transport, which can efficiently process liquefied hydrogen boil-off gas created during transport. According to the present invention, the vessel for liquefied hydrogen transport comprises: a hull; a liquefied natural gas storage tank installed on the hull to store liquefied natural gas; at least one liquefied hydrogen storage tank installed on the hull to store liquefied hydrogen; a combustion engine receiving the liquefied natural gas to generate power; a fuel supply line supplying the liquefied natural gas from the liquefied natural gas storage tank to the combustion engine; a reliquefaction line receiving liquefied hydrogen boil-off gas created as the liquefied hydrogen evaporates naturally from the liquefied hydrogen storage tank to collect the liquefied hydrogen into the liquefied hydrogen storage tank after undergoing a reliquefaction process; a compressor installed on the reliquefaction line to compress the liquefied hydrogen boil-off gas; a cooling unit installed on the reliquefaction line at the rear end of the compressor and cooling the liquefied hydrogen boil-off gas through an independent cooling cycle; an expander installed on the reliquefaction line at the rear end of the cooling unit to insulate and expand the liquefied hydrogen boil-off gas; a gas-liquid separator installed on the reliquefaction line at the rear end of the expander to separate the liquefied hydrogen and the liquefied hydrogen boil-off gas; a fuel supply line supplying the liquefied natural gas from the liquefied natural gas storage tank to the combustion engine; and a circulation line branching from the gas-liquid separator to supply the liquefied hydrogen boil-off gas to the reliquefaction line at the front end of the compressor.
