Wind Loads |

Wind loads are calculated using:
(1)
where:
•CWy(αw), CWz(αw) and CWθ(αw) are the Wind Coefficients in surge, sway and yaw respectively for an equivalent wind incidence of αw
•ρa is the air density
•AT is the transverse area of the body which is exposed to wind action
•AL is the longitudinal area of the body which is exposed to wind action
•uw is the equivalent wind velocity
The equivalent wind incidence αw is obtained using:
(2)
where:
•νw is the (global) wind velocity
•βw is the wind direction as defined in Wind and Current Directions.
The equivalent wind velocity uw is given by:

•*FLOATING BODY is used to define a floating body and its associated properties. Specifically, inputs such as longitudinal and transverse areas are used in the computation of wind loads.
•*WIND is used to specify wind loading.
•*WIND COEFF is used to specify wind coefficients used to determine the wind loading on a floating body.
