Abstract
In the period between May 2019 and May 2020, the movements of the Cabauw observational tower have been monitored. This monitoring campaign was set up to monitor the behaviour of the tower before (period 1), during (period 2) and after (period 3) replacement of the stay cables. The observations during these periods have been reported in TNO report 2020 R11120A [1]. During the campaign some extreme wind events were registered by KNMI on site. KNMI has asked TNO to analyse the measured data at the tower during these extreme wind events. The goal of this analysis was to determine whether the tower showed different behaviour during these events, in comparison with the behaviour during normal wind conditions as described in TNO report 2020 R11120A [1]. Chapter 2 summarizes the set-up of the monitoring campaign. Chapters 3 and 4 each describe the analysis of a specific wind event. Chapter 5 gives the conclusions. Annex A explains the applied procedure to synchronise the data sets obtained during the extreme wind events. Annex B gives values of the damping of the tower as determined from the measurements.
