AqualisBraemar, engaged by China Road and Bridge Corporation (CRBC), the contractor of Tseung Kwan O Cross Bay Link Project, completed its work on Hong Kong’s Tseung Kwan O Cross Bay Link main bridge last week as the arch bridge section completed its floatover installation.

The arch bridge is 200 meters long and approximately 12,000MT, it was built in Nantong by Nantong Zhenhua Heavy-Duty Equipment Manufacture and finally installed in a floatover operation onto the bridge piers.

“We started engaging CRBC on this project in October 2018 and were officially contracted to start the engineering design from March 2020. Though a city bridge project, we had to bring all our experience to bear on the project,” said Yongfei Peng AqualisBraemar’s China country manager. “This was the heaviest arch bridge installed in one piece by a floatover operation and the biggest challenge was the super high elevation of the main bridge on the floatover barge and the wet tow during the winter season when sea conditions in Taiwan strait are normally not very favourable for tows.” 

AqualisBraemar brought their deep experience of floatover operations from its work in offshore oil and gas and completed a scope consisting of supporting the transportation and installation engineering design, site supervision on loadout, transportation and installation.

There will be two more side spans (less than 3,000MT each) to be installed by floatover in April and 9 more concrete bridge segments installed by lifting for the same project in Hong Kong. The 1.8km long bridge, featuring a cycle lane and footpath with trees and other green features is expected to open in 2022. The two-lane highway spanning Junk Bay will connect Lohas Park and the industrial district at the southeastern part of Tseung Kwan O to Tiu Keng Leng via the Lam Tin Tunnel, offering an alternative route from Wan Po Road.
