Traffic volume
Port traffic: Traffic volume is heavy, with 260 vessels entering or leaving port every day, and very large numbers of small vessels entering or leaving the fairways at any given time. In the 2006–2010 period the VTS communication service managed 362,000 instances, the navigation assistance service managed 323,000 instances, and the traffic control service 456,000 instances. In 2010, the port had a total of 97,276 ship movements, and around 70,000 ship movements involving ships over 60 m LOA. Despite all the capacity increases, there are still bottlenecks in the traffic. As of 18 March 2011, anchorage waiting time for a ship bound for the Nanjiang terminals was 2–4 days
