On March 25th, according to CCTV News, it is expected that China's "Haiji Erhao" will be officially launched this morning, and upon successful installation, it will break several Asian records for operating depth, height, weight, and more.
It is reported that "Haiji Erhao" is Asia's first deepwater pipeline installation, with a total weight of nearly 37,000 tons, equivalent to almost an entire "Bird's Nest" stadium in terms of steel usage.
The subsea pipeline support structure, known as a "jacket," is the most widely used marine oil and gas production facility worldwide. The jacket serves as the foundation, supporting large offshore oil and gas production platforms above the sea surface.
The "Haiji No.2" has a total height of 338.5 meters, surpassing the height of the main building of Beijing's Guomao Phase 3. Over 95% of its parts operate long-term below the sea surface, enduring harsh sea conditions such as winds, waves, and internal wave flows.
Designed to withstand severe sea conditions occurring once in a century, the "Haiji No.2" is the tallest and operates at the greatest water depth among similar structures in Asia.
Once installed, "Haiji II" will stand tall in waters 324 meters deep, partnering with Asia's first cylindrical "offshore oil and gas processing plant" to jointly develop China's first deepwater oil field—Luhua 11-1 oil field. Together, they can process nearly 5,600 tons of crude oil per day.
