Located in one of the most active typhoon prone regions in the world, the Tsing Ma Bridge in Hong Kong is the longest dual-deck suspension bridge in the world. Carrying both road and rail traffic, with a central span of 1,377 metres, Tsing Ma is one of three principal structures linking the airport to central Hong Kong and Kowloon.
Gill’s ultrasonic anemometers are positioned in the middle of the main span of the bridge on both north and south sides of the deck on 8.96metre long booms. These anemometers help provide the Highways Department with continuous wind data to ensure road and rail user safety, by assessing the physical and structural conditions of the suspension bridge, particularly during extreme weather events.
Because of their success and long-term, maintenance-free reliability in these applications, Gill’s three axis anemometers have also been installed on the Hong Kong – Shenzhen Western Corridor – linking the New Territories to the Chinese mainland and Gill’s MetPak weather stations have been installed in many prestigious buildings, such as the luxury Peninsula Hotel and the IFC Tower.
