Construction of record-breaking deepwater jacket Haiji-2 completed

Haiji-2, the first deepwater jacket in Asia designed and built independently by China National Offshore Oil Corp, completed construction in Zhuhai on Tuesday, reported CCTV News.

Jacket platform is the “foundation” for supporting and fixing the huge body of offshore oil and gas platform, which is widely used in the world. With a total height of 338.5 meters and a total weight of 37,000 tons, the jacket of Haiji-2 uses more than 20,000 tons of high-strength steel, making it the first case of large-scale application of domestically produced high-strength steel in marine engineering.

The project has broken multiple records in Asia in terms of structural height, weight, operating depth, and construction speed, signifying that China’s capability of independent design and construction for deepwater super-large jacket platforms has reached the world’s advanced level.
