The installation of the offshore oil and gas platform on Saturday in the eastern waters of the South China Sea, which weighs more than 15,000 tons, sets a new weight record for China's offshore oil and gas platform dynamic positioning float-over installation, said its operator China National Offshore Oil Corporation.

It has also filled a gap in domestic technology while further ensuring domestic energy security, it said.

The Enping 20-4 platform has been successfully docked with a submarine jacket in the Pearl River Mouth Basin in South China's Guangdong province on Saturday. Enping 20-4 platform's docking with submarine jacket was completed, for the first time, independently by Chinese companies, including design, calculation and construction, it said.

The Enping 20-4 platform is located in one of the oil fields with the fastest growth of crude oil output. When the Enping oil field enters full production, its peak annual output of crude oil will exceed 3.6 million tons, which will inject new impetus into China's economic and social development, said CNOOC.

CNOOC achieved a total oil and gas production of 120 million tons of oil equivalent in 2022, setting a record high, according to a report released by the company on Thursday.
