The purpose of the present invention is to change the fixing method of a mooring chain for the spread mooring of a floating marine structure and to apply a primary and secondary double-fixing structure to the mooring chain, thereby reducing weight by simplifying a reinforcing structure for a hull structure, and implementing more efficient mooring when mooring a marine structure in a designated sea area. The present invention to achieve such a purpose comprises the following steps: a mother ship moving step for moving a marine structure to a work sea area; a mooring preparation step for extending a mooring line of the mother ship to the outside, pulling up a mooring chain (60) extended to the seabed, and connecting the mooring chain with the mooring line; an initial mooring step for pulling up and fixing the mooring chain (60) to the mother ship by using the mooring line of the mother ship; a tension adjusting step for adjusting the tension of the mooring chain (60) by using a chain stopper (36) installed at a side shell (30) of the mother ship; and a storage step for storing a surplus mooring chain (60) in a chain locker (68) after adjusting the tension of the mooring chain (60). |
