In what wind speed can an MCWP work?

All MCWPs used out-of-doors or otherwise exposed to wind whilst in service shall be regarded as being affected by a minimum wind pressure in accordance with:

Minimum design wind data, in service
Freestanding or MCWP during erection/dismantling: 12,7m/s (Wind velocity), 100N/m2 (Wind pressure)
Tied MCWP: 15,5m/s (Wind velocity), 150N/m2 (Wind pressure)

Wind forces are assumed to act horizontally at the centre of the wind area of the exposed structural parts of the MCWP.
