one wind direction

hi all,

asking;

can we consider one wind direction only in an onshore calculation?

if yes, what scenario might that be.?

it might be the facility is facing thru sea and the other direction has some obstruction that's why we only consider one direction?

need your opinions and guidance guys.
thanks

anybody?

Why not ?

There are endless real occasions where adjacent structures mean that wind can only act in one direction on a given piece of plant.
