The Comparative Study Of Tonggu Channel Phase Ⅱ Program

After 30 years of development, Shenzhen Port has quickly become the world's fourth largest container harbor. However, as bear the most transport parts of Shenzhen port, Western Harbor has not its own launch out route, more than 3000 tonnes of ships entering and leaving the port must through Hong Kong Ma Wan Channel.Because of Ma Wan Channel has much limits, and economy no good, outgoing channel became a bottleneck restricted Shenzhen Western Harbor development. Tonggu Channel its been warmly looking forward to, and spent so much money, has suffered severe criticism because of its safety and economics is no good. The navigation utilization is very low. Shenzhen Western Harbor still has his bottlenecks.According to the Shenzhen development planning, with Dachan Bay container terminal was put into production, and CCT, SCT extension, are indicate that Shenzhen Western Harbor will and being running into a new round of rapid development period, but the fairway is not suit to port development. To relieve the bottle-neck of Shenzhen West Harbor, I believe that the phaseâ…¡project of Tonggu Channel will implement in the very near soon. At present, there are two selections about Tonggu Channel phaseâ…¡, one is a expansion based on existing project, expanding into a two-way channel, another is based on the former West program, at the request of 140 thousand tonnes of container ship as a single-way channel. As the Tonggu Channel second phase projects, pass through the mouth of the Pearl River white Dolphins protected area and other environmentally sensitive areas, and the project investment reach to 2 billions. What is the most suitable?This article discussed channel's safety of this two selections from the weather, current, vessel traffic flow, traffic accidents, abnormal accident; and discussed its economics from the channel dredging and maintenance of this two programme; from the environmental protection, as well as other factors that may affect the success of the fairway to compare it. Through a series of calculations and investigation, analysis and demonstration, then give some opinions about Tonggu Channel phaseâ…¡, and wish to offer some help to the construction of it.
