Distortion preventing device for FPSO topside module support

摘要

The present invention relates to a mechanism for supporting a topside module (20) on a stool (10) with a horizontal bearing (24) and a vertical bearing (26) interposed therebetween, the mechanism being provided on the bottom surface of the topside module (20) A horizontal support member 30 for holding a predetermined clearance 32a and 32b; And a vertical support member (40) installed at the upper end of the stool (10) so as to maintain a constant clearance with the topside module (20). This minimizes displacement of the topside module even in urgent matters such as blast, thereby reducing another explosion or danger, and securing time for safe escape of crew members.
