Background

The pipeline's source is the Yacheng 13-1 and Yacheng 13-4 Offshore Gas Field, on the South China Sea, 91 kilometers southwest of Hainan Island. In October 2020 ownership of the pipeline was transferred from CNOOC to PipeChina.

Yacheng-Hong Kong Gas Pipeline Gaolan Branch 中海油崖港输气管线（崖城-香港）高栏支线

The pipeline has a two-way gas transmission function, running from CNOOC Yagang Gas Pipeline (Yacheng-Hong Kong) at 694 kilometers to Gaolan Natural Gas Processing Terminal in the East Oil Region of the South China Sea, Zhuhai, Guangdong province. It also ended the disconnection of the submarine natural gas pipeline networks in the two major oil areas in the east and west of the South China Sea, forming "one network" overall. At this point, the abundant natural gas in the two major oil regions can be uniformly and flexibly allocated according to the market demand in Guangdong, Hong Kong, Macao and Hainan, and the ability to ensure supply is enhanced. The pipeline is very helpful to the construction of Guangdong-Hong Kong-Macao Greater Bay Area and Hainan Free Trade Port.

Yacheng-Hong Kong Gas Pipeline Shenzhen Branch 南海天然气登陆深圳项目

The pipeline is located in the sea on the west side of Nanshan District, Shenzhen City, Guangdong Province. It is planned to open a hole for the existing Yacheng-Hong Kong Pipeline and build a new submarine gas pipeline about 7km long, landing at Shenzhen Mawan Power Plant.
