To suppress reaction of carbon dioxide and moisture upon transferring liquefied carbon dioxide, and efficiently load and unload liquefied carbon dioxide into a tank.SOLUTION: A transfer method of liquefied carbon dioxide comprises: connecting a connection pipe for connecting to an external facility arranged outside a floating body to a pipe that communicates with the inside of a tank provided in the floating body; sending replacement gas whose water content is adjusted to a predetermined upper limit or less to the inside of the connection pipe and the pipe, to replace the inside of the connection pipe and the pipe with the replacement gas; replacing the inside of the connection pipe and the pipe from the replacement gas to carbon dioxide gas; and transferring liquefied carbon dioxide between the external facility and the tank through the connection pipe and the pipe.SELECTED DRAWING: Figure 5
