Fugro has been contracted to undertake environmental measurements on the proposed Coastal Highway project in Norway.
Seven fjords stud the path planned for the Coastal Highway, also known as Route E39. Currently, ferries serve each fjord, but the highway project aims to give motorists a seamless drive from Kristiansand in the south to Trondheim in central Norway.
Suspension bridges, floating bridges and floating tunnels are possible alternatives to the ferries.
Before a decision is taken on which method is used, each fjord needs to be surveyed for ocean surface waves, internal waves, wind profiles and current profiles.
Fugro’s NOK111M (£9.3M) contract commits the company to examine Sulafjord, Vartdalsfjord and Halsafjord.
The company is to build several 80 to 100m tall onshore wind masts to provide wind profiles. Offshore, LiDAR meteocean buoys will be used to measure wind speed and turbulence above the fjords. The aim is to better understand the wind forces on the roadway between the bridge towers.
The agreement calls for measurements to be taken from the planning phase until the bridges are commissioned.
