Located in the South China Sea, the Deep Sea No. 1 Phase II cluster consists of four offshore gas platforms and is a major natural gas source for southern China. In just one second, the rigs produce enough gas to power a five-person household for a month. The cluster connects China's first 100-billion-cubic-meter offshore gas field with its latest deepwater development. CGTN reporter Wan Hongjia stays on the rig to report on how this deep-sea energy lights up cities across the region.
