Disclosed are an independent liquefied hydrogen storage tank and marine transportation means equipped with the same. The independent liquefied hydrogen storage tank comprises: a primary barrier which provides primary airtightness while directly contacting the liquefied hydrogen stored inside; a partition structure installed at a certain distance from the outside of the primary barrier to form a space between the primary barrier and the partition structure arranged to surround the remaining surface except the upper surface of the primary barrier; a vacuum insulation layer prepared by vacuum forming a closed space formed between the partition structure and the primary barrier; a cryogenic insulation layer installed on the outer surface of the exposed upper surface of the primary barrier; and an auxiliary insulation layer installed to surround the outside of the partition structure and cryogenic insulation layer. According to the present invention, by using the liquefied hydrogen storage tank, the evaporation rate (BOR; boil-off rate) of liquefied hydrogen can be significantly reduced during the transportation process and ultimately has the economic effect of minimizing energy loss.
