According to the detachable attachment type propulsion system of the present invention, a detachable attachment type propulsion system can be attached to the aft end of a floating structure having no propulsion system, so that the floating structure can be moved to a desired place without a tug.

In addition, since the tugboat is not used, the floating structure can be moved to a desired place at a lower cost than the conventional one.
