A mooring apparatus includes a housing positioned on a seabed by being lowered from a hull, a driven pile inserted into a first through hole formed in the housing, configured to come out of the housing on the seabed, and embedded in and fixed to the seabed, and an anchor line configured to come out of a guide hole formed in the driven pile when the driven pile is embedded in and fixed to the seabed and moving downward through the seabed so as to reinforce a supporting force of the driven pile.
