PURPOSE:To perform safe launching of a marine structure by a method in which the leg of one end of a marine structure on a quay is mounted on a float and as soon as the leg is lowered, the float is landed on the bottom by charging water into it, the operations are repeatedly made to erect the marines structure in water, and then the legs are pulled up at the same time. CONSTITUTION:Turnable and movable trucks T1-T3 are each set to legs L1- L3 of a rig 6 on a quay, and the leg L3 with the truck T3 is mounted on a barge 7 floating in contact with the bank by turning toward the sea area the rig 6 around the leg L1 as a shaft. Also, under the condition that the barge 7 is separated from the quay P, the leg L3 is brought down and the barge is landed on the bottom by charging water into it. The legs L1 and L2 are orderly mounted on the barges 9 and 8 by turning the rig 6 around the leg L3 as a supporting point, the barges 9 and 8 are landed on the bottom under water by charging water into them while extending the legs L1 and L3, the legs L1-L3 are pulled up at the same time, and the rig 6 is floated. |
