Ramboll has prepared detailed fatigue analyses of two typical 300 m guyed masts in Sweden. The purpose of the investigation was to establish the lifetime of guyed masts now that they are around 50 years old.
On the 15th of May 2016 the old 320 m guyed mast in Borås was exposed to sabotage and 200 m of the top of the mast fell down to the ground. Due to the collapse Teracom wanted a new mast designed, manufactured and installed as soon as possible.

A new overhead transmission line is needed in order to secure the quality of supply in Denmark. Denmark puts a great effort into reducing CO2 emissions by expanding the production capacity based on renewable energy. Consequently, a more flexible electricity grid is needed to be able to transport the power from the offshore wind parks to the consumers as well as increasing the transmission capacity between international markets.
When antennas from different telecommunication operators were installed in the overhead transmission line towers of Energinet.dk, a static analysis of the towers and the foundation was needed. Ramboll assisted Energinet.dk with all antennas installed in the their towers.
In order to enhance the view of Little Belt, 12 km of overhead line was removed and replaced with cable. Ramboll was responsible for the project description of the dismantling of the cables and the 120 m tall towers – as well as designing foundations for the new towers.
