Technology survey for renewable energy integrated to bridge constructions, Wave and tidal energy
MetadataVis full innførsel
E39 is a road that is located on the west coast of Norway and extends from Kristiansand in the south to Trondheim in the north. Currently, a number of ferry crossings are required to traverse its entire length. The Transport Ministry has given a mandate for the project “Ferry Free E39” to assess the technological solutions for the crossing of eight large fjords without ferries. The fjords crossings range from 1.5 km to 25 km in length and have depths up to 1300 m. Proposed solutions for the crossings that are under consideration consist of suspension bridges, floating bridges and submerged floating tunnels. Part of the project is to consider how the construction of the crossings can be combined with devices that produce energy from waves, tides, wind and the sun. The idea is that, by using the bridge construction as part of the facility, the costs of the renewable energy power plants could be reduced and therefore be more competitive.
