Do you know carbon fiber + fiberglass! The world's longest one-piece composite truss bridge was hoisted in Norway?
The EPC provider fabricated, transported and delivered a 42-meter-long fiberglass composite bridge for pedestrians and cyclists.
CSub (Arendal, Norway), an engineering, procurement and construction (EPC) provider of fiberglass composite products and solutions, has successfully delivered the world's longest composite truss bridge to the Paradis City Railway Station in Bergen, Norway. The pedestrian bridge was transported to the site in one piece by ship, ferry and multi-wheeled transporter after fabrication and then hoisted into place in a matter of minutes. The bridge is 42 meters long, 7 meters wide and weighs approximately 47 tons. Designed for pedestrians and cyclists, the bridge now allows them to safely cross a heavily trafficked road as well as the local city's train to the Bybanen Airport. Notably, CSub claims that the bridge is the largest of its kind and is constructed entirely from fiber reinforced polymer (FRP), setting a new world record. To meet stringent requirements for strength and stiffness versus weight, the bridge uses a combination of carbon fiber and fiberglass. The bridge once again demonstrates the advantages of using FRP, such as an optimal weight-to-strength ratio, long-term durability, minimal maintenance and a reduced carbon footprint compared to other materials.
CSub manufactured the bridge on behalf of Consto as main contractor, FiReCo for engineering and Vestland Fylkeskommune (VLFK) as end customer. VLFK was supported by Multiconsult (general technical consultancy) and Royal HaskoningDHV (composite design and production quality control). Royal Transport was responsible for transport and installation. "On behalf of the entire CSub team, we are proud to be an important part of this groundbreaking project," says Anders Holm, CEO of CSub. "We are very grateful for the opportunity to work with a solution-oriented team, which is essential to the realization of such a project. Moreover, it was a rare experience to witness the spectacular transport and installation of the bridge first-hand". Founded in 2003, CSub serves a number of industries including energy, civil engineering, renewable energy and aquaculture, and is particularly known for the supply of non-metallic subsea structures. Since its founding in 2006, CSub has grown into HighComp, a well-known brand in the aquaculture sector. Together, the two companies form the CSub Group, committed to innovation, quality and sustainability in composite construction.
