弁を掘削する移動ブラットフオーム方式などがある。For offshore drilling equipment, there is an artificial island method in which an island is constructed by building an embankment in the sea, and a defense is excavated in the same way as on land.A steel jacket is fixed to the seabed by piling, and this is used as a platform on which the drilling equipment is mounted. A structure constructed on the seabed by installing a drilling rig on a platform with a purge on the bottom, towing it to a predetermined location at sea, and then injecting seawater into the purge to allow it to settle. There is a moving bratform method that connects objects and platforms to form a rig and excavates a defense.

問題があった。By the way, since the barge 6 is attached to the lower surface of the platform reef as described above, the ship platform foam may be shaken by waves etc., causing the legs 8a to 611 to be pushed from above the supports 3a to 3d. K-fitting is extremely difficult. Moreover, the legs 5a to 5d are the supports 3a to 34.
The legs 5 to 5d and the supports 3 to 3d may be damaged by the collision. This caused many problems, including delays in the construction period as the work had to be carried out on days with relatively few waves.
