Hyundai Engineering & Steel Industries used the GSP Neptun, the largest heavy lift barge crane in the Black Sea, to help with the construction of the third Bosphorus Bridge over the Bosphorus Strait at Istanbul in Turkey.
At 59 metres the Yavuz Sultan Selim Bridge will be the widest in the world, said lifting contractor GSP Offshore. It will have eight road lanes and two rail tracks. The bridge’s towers will reach 322 m high.
GSP Neptun started work unloading the first floor slab on 25 December 2013. The first of the steel slabs for the bridge was placed on 26 December 2014. A second 450 tonne floor slab measuring 4.5 m was placed on 9 January 2015, on the Asian side of the strait, a company spokesperson added.
GSP Vega, AHTS, performed the crane barge transportation from Constanta to Istanbul and back.
The new bridge will be the third to connect the Asian and European sides of Istanbul and will form part of the Odayeri-Paşaköy section of the Marmara motorway.
