Port Klang's vessel traffic management system (VTMS) under the supervision of the PKA was implemented in order to ensure greater navigational safety in the port waters.

The ACC or Area Control Centre's radar on the 19th floor of the Westport commercial building covers a radius of 26 nautical miles offshore. The other two radar sites are located on Pulau Angsa and Bukit Jugra.

This system provides information on vessels transiting the harbour such as cargo onboard, last and next port of call and the vessel's particulars. The centre also provides an attending pilot accurate information on the vessel's position and the density of traffic converging on the same destination, thus enhancing passage planning.
