Tonggu Channel Closed for Undersea Pipeline Construction
Considered as one of the busiest waterway off western Shenzhen, the Tonggu Channel will be closed for four days for the construction of undersea gas pipelines. The pipelines are part of China’s second west to east natural gas transmission pipeline.
The pipeline extends to about 8,600 kilometers from Xinjiang to Guangdong and Hong Kong. The pipelines are designed to transport around 30 billion cubic meters of natural gas annually. The construction of the undersea pipeline in Tonggu Channel will extend it further to 30 kilometers and can handle 6 billion cubic meter of natural gas annually. Parts of the piping will be built 27 meters below sea level and is said to be the deepest undersea piping in the world.
The undersea piping in the west and east project will pass through several channels in western Shenzhen, which is the most complicated and busiest waters in China in which more than 500,000 ships pass the waters each year. And more than 100 passenger ships travel these waters between Hong Kong, Guangdong and Macao every day.
Tonggu Channel is the most use route for large ships that are entering the ports in western Shenzhen. During the construction, large ships will be using the Ma Wan Channel in Hong Kong, ships not using Ma Wan Channel will stop at other ports.
