SSPA supports the Norwegian Public Roads Administration in the design of safe crossings of Bjørnafjorden
SSPA Sweden proudly announces the assignment from the Norwegian Public Roads Administration (NPRA) to conduct risk analysis and simulations of maritime traffic with different floating bridge and submerged floating tunnel design options for “Project Bjørnafjorden”.
NPRA is investigating a gigantic infrastructure project related to the 1,100 km long “Coastal Highway Route E39”, where it will be exploring the options for replacing seven existing ferry crossings between Kristiansand and Trondheim with fixed links. The fjords are both broad and deep, which requires large investments and larger structures than anything that has previously been built in Norway.
The crossings require different concepts and solutions for which the technical implications and anchoring systems for floating structures will be of particular interest. Bjørnafjorden is a challenging fjord since it has a width of 5 km and a depth of up to 650 meters. This project has significant international interest and requires cutting-edge national and international know-how, including experience and technologies from maritime operations.
“It is vital for us at the Norwegian Public Roads Administration to choose a safe option and to create a design basis for construction of the crossing structures. SSPA will provide expertise and risk management for this project,” says Mathias Kjerstad Eidem, Project Manager at NPRA.
SSPA has been selected as consultant and expert team to work on “Project Bjørnafjorden”. SSPA’s project team will analyse three main options: a suspension bridge, a floating bridge and a submerged floating tunnel, as well as combinations of them. SSPA will also investigate the current maritime traffic and make calculations on what maritime traffic will look like in the year 2070.
“It is important for our team at SSPA to support the Norwegian Public Roads Administration with independent and validated information,” says Johan Gahnström, Project Manager at SSPA.
