The main structure of Haiji-2, Asia's largest deepwater jacket designed and built independently by China National Offshore Oil Corporation (CNOOC), was completed on Tuesday in Zhuhai, south China's Guangdong Province, said CNOOC, the country's top offshore oil and gas company.

A jacket serves as the foundation of the offshore oil and gas platform. Used to support the huge body and tonnage of an offshore platform, it is the most widely used equipment in offshore oil and gas development globally.

Haiji-2, with a height of 338 meters and a weight of 37,000 metric tons, now holds a record in terms of height and weight in Asia, signifying significant progress in China's independent design and construction capabilities for deep-sea large-scale offshore oil and gas equipment, the company said.

The completed platform will become the tallest offshore oil and gas production platform in Asia, with a total height of 428 meters and total weight exceeding 50,000 tons.
