The invention relates to a process for sectionally closing and hoisting pile legs of a self-elevating offshore oil platform through a crawler crane, and belongs to the technical field of equipment hoisting processes. The crawler crane at the corresponding energy level is used for closing the pile legs; the pile legs of the self-elevating platform can be closed on land or closed after entering the sea according to the height difference and the performance parameters of the crawler crane. According to the process, the traditional construction process is changed; the construction cost is reduced; the construction safety is ensured; the construction period is decreased; the crawler crane is used for closing the pile legs, so that the construction cost can be reduced; the hoisting of the pile legs and the azimuth adjusting of the self-elevating platform are integrated and comprehensively managed, thereby accelerating the construction progress.
