An optimal use of existing masts and towers is a key issue for owner of masts and towers. Using the experience of Ramboll within analysis and reinforcement of existing structures can prove to be highly cost efficient for any project.

Extending the capacity of masts and towers may be necessary for a number of reasons:

The number of antennas and feeders may be increased compared to what the structure was designed for.
Change in the design codes and standards
Under design from the beginning
Fatigue problems
Some times a better knowledge to the wind and ice climate can lead to an increased capacity of the mast and towers.

For many years Ramboll has assisted clients to extend the capacity of towers and guyed masts to carry more antennas and feeders. For the guyed masts an adjustment of the initial tensions of the guys, replacements of guys and full dynamic analysis may prove to be an effective way to extend the capacity, and in some cases also reinforcement of the structural members may be necessary. When it comes to selfsupporting towers a combination of full dynamic analysis, rearrangement of feeders and cables and reinforcement of the structural members may solve many capacity problems.

We have of course also various ways to increase the capacity of the foundations if necessary.
