dc.description.abstractThis report describes the construction and installation of the Bjørnafjorden floating bridge. The bridge consists of a cable stay bridge in the south connected to a 4.5km long floating bridge. The south end of the floating bridge has high columns to attach to the cable stay bridge and is called the “high floating bridge”. The “high floating bridge” transitions to the “low floating bridge” which spans most of the Bjørnafjorden. The floating bridge is moored to the seabed with a total of 12 mooring lines. The Construction and installation of the bridge is split into sub-operations: • Construction of the Cable stayed bridge • Construction of abutments • Assembly of bridge girder segments and pontoons with columns into high- and low floating bridge sections. This operation takes place in Søreidsvika, a fjordarm of Bjørnafjorden • Connection of the high and low floating bridge sections in Søreidsvika • Pre-installation of mooring system • Installation of the north section which consists of 2 pontoons to the north abutment. • Towing of floating bridge from Søreidsvika to the final installation location • Installation of the main floating bridge section including hook up of mooring lines The piers and the tower of the cable stayed bridge will be constructed using climbing formwork. The bridge concrete box girder is constructed using movable scaffolding. The cable stayed bridge deck is installed using the balanced cantilever method, working out from the tower towards the side span and the main span simultaneously. The sections are lifted from barges by derrick cranes.en_US
