BOA delivers main plinth for Storstrøm Bridge
Norwegian offshore services provider BOA Offshore recently completed a load-out, transport and float-off of the main plinth for the new Storstrøm Bridge in Denmark. The company deployed its semi-submersible heavy deck cargo barge BOAbarge 34 with the 25,000 DWT capacity for the job.
The new bridge is being built by the Danish Road Directorate and will connect Zealand with Falster. The bridge will be the 3rd. longest in Denmark with 4 km in length.
The Plinth 1C, with a weight of 12.250 tonnes was loaded onto the BOAbarge 34 by skidding method. Thereafter the BOAbarge was towed and moored in a four point pre-laid mooring system close to the installation site before the BOAbarge 34 was submersed to a depth of 21.5 metres aft and 17 metres forward allowing the plinth to safely float free before being towed to final position.
The family-owned BOA delivered the job for SBJV, the Italian joint venture between Itinera, Grandi Lavori Fincosit and Condotte. The new Storstrøm bridge will be one of the few bridges in the world to feature a two-track high-speed railway, a dual carriageway, a combined cycle and pedestrian path, all on one cross section. The €278 million bridge is part of the railway corridor between Denmark and Germany.
