Hong Kong Telekom and Hong Kong Harbour Authority have recently completed factory acceptance testing at Omniflex's premises in Durban for a system to monitor all the radar outstations for the Hong Kong Harbour Traffic Management Centre. Based on the award-winning Maxiflex programmable RTU system, Maxiflex collects data from the 18 radar outstations located over a wide geographic area some of which are very remote and inhospitable and accessible by helicopter only. The collected data is transmitted back to Hong Kong Harbour Traffic Management Centre via a microwave data communications network (using Omniflex's Conet/s protocol) provided by Hong Kong Telekom. Omniflex was chosen as preferred supplier owing to its networking and engineering flexibility, ability to interface directly (serial communications) to UPS systems at the radar stations and to remotely re-program outstations from the engineering station located at the Traffic Management Centre. The system also provides control outputs that the scada initiates activating station devices and running diagnostic tests on the outstations.
With Hong Kong Harbour being one of the busiest ports in the world, up-time and speed of data collection were crucial and Maxiflex's ability to provide multiple full duplex parallel communications paths (Conet/s) for each of the 18 outstations. Being the junction of two different forms of maritime transport - the large ocean-going vessels from the Pacific Ocean and the smaller, coastal and river trade craft from the Pearl River - and the only modern, fully developed deep water harbour between Singapore and Shanghai, Hong Kong is the focal point of all maritime trading activities in Southern China. In 1999, Hong Kong handled a total of 169 million tonnes of cargo through its port and 16,2 million TEUs, making it the busiest container port in the world for the sixth consecutive year. With its local distributor, Omniflex has ensured the ready availability of spares, technical support and maintenance back-up for the system.
