The present invention is to provide a liquefied hydrogen storage tank equipped with a high-performance insulation system and a maritime transportation means including the same, so that liquid hydrogen can be stored and transported with minimal heat loss for a considerable period of time during maritime transportation of hydrogen. An independent liquefied hydrogen storage tank and marine transportation means equipped with the same are disclosed. According to the present invention, the disclosed independent liquefied hydrogen storage tank comprises: a primary barrier which provides primary airtightness while directly contacting the liquefied hydrogen stored inside; a secondary barrier which is installed at a certain distance from the outside of the primary barrier and forms a closed space between the primary barrier and the secondary barrier; a vacuum insulation layer prepared by forming a closed space with a vacuum; an auxiliary insulation layer installed to surround the outside of the secondary barrier; a plurality of primary barrier supports installed between the primary barrier and the secondary barrier to support the primary barrier; and a plurality of secondary barrier supports installed between the secondary barrier and the hull structure to support the secondary barrier.
