On May 19, 2021, China Central Television’s “Morning News” program reported the successful installation of the Lufeng 14-4 central platform—the largest offshore crude oil production platform independently designed and built in China. Located in the Pearl River Mouth Basin, the platform stands atop a seabed 145 meters deep, with an overall height of 218 meters, marking a further enhancement in China’s capabilities for constructing and installing large-scale offshore oil and gas facilities. The platform was constructed by CNOOC, which selected Tianyi’s DQ90 top drive for this critical oil‑and‑gas extraction operation. This choice was driven not only by the superior quality of Tianyi’s top drives but also by their exceptional service performance. Since its establishment, Tianyi has continuously pursued innovation, steadily improving the technological sophistication of its products. Its developed top drives now boast 22 patented technologies, and their key performance parameters—compared with similar foreign models—demonstrate more reliable drilling and safety characteristics. The equipment also features easy parameter adjustment, intuitive data display, and a user-friendly human–machine interface, along with advanced fault diagnosis and analysis capabilities, and the ability to store historical data. These attributes have earned widespread market recognition, with Tianyi‑made top drives now operating in major oilfields around the world. Whether measured by market share or service quality, Tianyi has firmly established itself as a leading manufacturer of top drives. Over more than a decade of collaboration with CNOOC, Tianyi’s top drives have consistently been among CNOOC’s preferred suppliers. Each unit carries classification society certification, and every offshore service engineer holds all the necessary qualifications required for working on offshore platforms. After rigorous training and passing formal examinations, they are authorized to provide on‑site services at sea. Unlike onshore drilling, offshore operations take place aboard a vessel that can sway violently in rough seas; many engineers experience dizziness and nausea during their first assignments on such platforms. Nevertheless, Tianyi personnel persistently overcome these physical challenges to successfully complete each drilling task, ensuring customer satisfaction. On February 19, 2019, Well Ying‑1 in Shunbei reached total depth at 2:20, with a measured depth of 8,588 meters. Tianyi’s DQ70 top drive set a new Asian record, making it Asia’s deepest well—earning the nickname “the Everest of the underground”! In 2021, China’s largest self‑designed and built offshore crude oil production platform, the Lufeng 14‑4 central platform, is poised to enter commercial operation. What further achievements will Tianyi’s DQ90 top drive deliver? Let us wait and see.
