                      On March 2, pipeline construction of Hong Kong branch of the Second West-East Gas Pipeline commenced offshore Dachan Island near Shenzhen, Guangdong province. The pipe-laying vessel ZHONG YOU HAI 101 laid welded pipelines at the bottom of the sea.
  
  Hong Kong branch of the Second West-East Gas Pipeline consists of two sections from Shenzhen to Hong Kong: Qiuyuling-Dachan Island subsea pipeline and Dachan Island-Longgutan subsea pipeline. Covering a total length of 29.04km and with a transmission station in Dachan Island and a receiving station in Longgutan, the Shenzhen-Hong Kong subsea pipeline has a designed transportation capacity of 6 billion standard cubic meters per year. The pipeline boasts the largest subsea pipe diameter and undergoes the most difficult construction condition in China. When natural gas arrives at Hong Kong from the Second West-East Gas Pipeline, Hong Kong would realize its multiple and timely gas supply, which in turn would drastically reduce its reliance on coal and lower carbon emissions from power plants, thereby improving the air quality in the region.
