Disclosed is a floating structure for producing hydrogen. According to an embodiment of the present invention, the floating structure for producing hydrogen comprises: a pretreatment unit removing impurities from natural gas collected from a gas well or an oil well, and including a moisture removal unit separating moisture from the natural gas; a natural gas liquid (NGL) extraction unit extracting NGL from natural gas passing through the pretreatment unit; a hydrogen production unit receiving at least a part of the natural gas passing through the NGL extraction unit, and reforming the natural gas, and producing hydrogen: and a hydrogen pretreatment supply line supplying the hydrogen generated by the hydrogen production unit to the moisture removal unit. The moisture removal unit includes: a distillation column extracting a hydrate repressor contained in the separated moisture; and a moisture removal reboiler connected to the distillation column, and heating the product supplied from a lower side of the distillation column by making the product exchange heat with the hydrogen supplied through the hydrogen pretreatment supply line, and returning the gas substances generated by heating to the distillation column. The present invention aims to provide a floating structure for producing hydrogen, which is capable of receiving natural gas and producing hydrogen on the sea.
