In the eastern waters of the South China Sea stands an oil platform located 200 km southwest of Shenzhen in Guangdong Province. Known as Enping 15-1 and put into operation last December, it is the largest offshore oil production platform in Asia. The platform is independently designed, built, installed and operated by China National Offshore Oil Corp. (CNOOC), the largest offshore oil and gas producer in China.
