A raft structure and Method for installing suction pile using the same

摘要

A structure for supporting an offshore plant (10) with a plurality of suction piles (12) on a slope and a seabed ground, comprising: a receiving hole (21) for supporting the suction piles (12) A frame 20 having a connector 22 extending horizontally to form a group; And a reinforcing member (25) fixed at a symmetrical position in the frame (20) and increasing horizontal resistance against the seabed ground. Accordingly, there is an effect of inducing quick and stable installation and installation of a large number of suction file groups installed on the submarine ground by using a raft structure of a steel material provided with a helical file for increasing the supporting force.
