<p>PURPOSE: A lift device for an offshore platform is provided to disperse the load of a hull concentrated on a pinion and prevent the plastic deformation of legs of an offshore platform. CONSTITUTION: A lift device for an offshore platform comprises multiple rotary pins, a first pinion (130), and a first guide (150). The rotary pins are installed on one side of a leg in the extension direction of the leg to be rotated. The first pinion is installed on one side of a hull (10) and vertically moves the rotary pins in a first area. The first guide is formed on the other side of the hull and supports the rotary pins in a second area when the vertical movement of the rotary pins in the first area is stopped.</p> |
