Special core construction tools for the installation of self-developed guide frame in China are put into operation.

According to CNOOC, the "Qinghai" equipment series for the installation of pipeline racks, which are independently developed and manufactured in China, have been used in the offshore installation of pipeline racks in the new wellhead platform project of the Dongfang 1-1 gas field. It is reported that the successful application of this equipment marks a key progress in the research and development of specialized tools for marine oil and gas engineering installation in China, and is of great significance for building an independent and controllable marine engineering equipment system and accelerating the cultivation and development of new productive forces in marine energy.
