<p>The present invention relates to a jackup rig spudcan (30) installed in the bottom of a leg (25) in a hull (20) in order to generate a supporting force to the ground on the seabed. The jackup rig spudcan comprises: a plurality of wings (35) radially installed in a spudcan (30) in order to be withdrawn; and an actuating means (40) connected with the internal end of each of the plurality of wings (35) in order to cause rectilinear movement of the wings (35). Therefore, the jackup rig spudcan can maintain a firmly supporting state by increasing a contact area due to the exposure of the wings even when part of the seabed ground is weak, thereby preventing conduction.</p> |
