Abstract: The non-skidway construction of jackets and self-propelled modular transporter (SPMT) loadout technology has features such as not occupying skidway resources, not requiring sliding equipment, a fast loadout speed, requiring less prefabricated process equipment, and the ability to reuse it. Compared to conventional construction methods, this technology has better economic advantages and can increase the production capacity of the construction site for jackets. Currently, there are no relevant engineering cases for reference in China. In this regard, taking a hundred-meter jacket project that uses this technology as an example, the critical techniques of this engineering case are systematically introduced from aspects such as process equipment design, foundation settlement prevention, and SPMT loadout plan design. This case can provide certain technical support for the subsequent application of this technology in China.

Key words: jacket construction, non-skidway, loadout, self-propelled modular transporter
