Of course not...but basic physics and engineering dictates we can minimise influences cheaply and easily during design that all combat successful imaging. Influences that are harder to fix once built.
Worst case...a pier that has a natural frequency harmonic in sync with applied average wind force...in other words this causes it to hum or resonate...which in turn adds amplitude to the natural freq....just sayin!
Motor resonances...no these are not an issue at play here.
