Abstract: This paper firstly expounds the impact of the application of digital technology and intelligent on the manufacturing industry technology in the field of information technology. The cutting-edge technologies related to intelligent manufacturing are then introduced in detail, and the latest industry status quo is briefly analyzed. Then, in conjuction with the unique characteristics of equipment construction in the current offshore petroleum engineering industry, it conducts an in-depth analysis, and clarifies the pain points brought to offshore petroleum engineering by the characteristics of discrete equipment manufacturing. Finally, according to the current status of discrete manufacturing, combined with the field practice accumulated over the years, through 3D model design, intelligent robots and other multi-dimensional exploration the digital and intelligent transformation are studied in this paper.
