A system for installing an offshore bridge according to the present invention is a system for installing a bridge between first and second platforms separated from each other. A guide post is vertically fixed on one side of a first platform. A guide bumper unit is arranged in one side of the bridge so that it can be coupled to the guide post. In a state one end of the guide bumper unit is supported on the guide post by a crane, the other side of the bridge is rotated on the guide post to be mounted on a second platform. In case of the installation of a structure like the bridge, the bridge is moved a lot by waves, wind, or others on the sea. Also, it is hard and spends a lot of time to install the bridge at the accurate position due to the installation tolerance between the two platforms separated from each other. Thus, the present invention is to safely install the bridge by rotating the bridge on a fixed portion after one side of the bridge is fixed at first in consideration of offshore conditions, thereby enabling easy and fast installation of the bridge while minimizing the movement of the bridge. Since the length of the guide bumper unit installed in one side of the bridge can be adjusted, the bridge can be installed at the accurate position in spite of the occurrence of the installation tolerance by adjusting the length of the bridge as much as the installation tolerance between the two platforms. According to the present invention, only one guide post is removed after the installation of the bridge, thereby reducing offshore work time and increasing the installation stability of the bridge. |
