  Industrial chimneys, launch vehicles and stacks are examples of large
diameter circular cross section structures which can be prone to cross-wind
vortex-induced vibrations. VIV has been extensively studied for both
fundamental and applied issues, but few documented studies concern high
Reynolds number regime (over 500 000) in atmospheric turbulent wind. This paper
introduces a field test on a slender light and low damped chimney designed to
experience supercritical VIV at moderate wind velocity. The chimney was
recently erected in a wind monitored field, near the Atlantic coast of France.
The purpose of this paper is to present the first vibration results obtained
during a sequential 13 days period in September 2020. A statistical analysis
has been performed on the amplitude and dominant frequency responses and
results are reported in term of probability distribution as a function of wind
speed and direction. VIV events of low (under 15 % of diameter) to moderate
amplitude (over 30 % of diameter) have been highlighted in a range of wind
velocity 25 % lower than expected, along with significant influence of the wind
direction. Low turbulent easterly wind giving vortex induced vibrations with
the highest amplitude.
