Sichuan Road & Bridge Group (SRBG) successfully installed the deck segments of the Hålogaland Bridge in Narvik Norway. This suspension bridge is the second longest suspension bridge in Norway. The deck segments were installed by the Heavy Lift Vessel (HLV) Uglen.
TWD played an instrumental role in determining the concept and detailed design of the mooring arrangement of both the Transport Vessel Korean Express and Heavy Lift Vessel. Additionally, TWD worked closely with our client SRBG, equipment provider B&B and Heavy Lift vessel owner UGLAND, to come up with an efficient work method for installing the segments.
The second longest suspension bridge in Norway, Halogaland Bridge, will be soon open to traffic. The total length of the bridge is 1,533 m with a span of 1,145 m.
All bridge segments were transported on the cargo vessel “Korea Express” from China to Norway. For installation of the deck segments, the vessel “Korea Express” that contained all bridge decks was positioned underneath the suspension lines and moored by a 6-point mooring spread. The deck segments were lifted from the “Korea Express” and installed by the HLV “Uglen” that was moored by a 4-point mooring spread.
In total, 6 mooring winches and 10 mooring lines were used to position both HLV and Korea Express during operation. Pontoons were used to decrease the initial load on the winch as result of the line catenary. Besides the assistance of TWD’s naval department, TWD performed the structural engineering of the temporary connections of all bridge segments and the design of all lifting arrangements. Additionally, TWD reviewed the seafastening design on the Korea Express.
