3103F.5.3.2 Current Velocity Adjustment Factors
An average current velocity (Vc) shall be used to compute forces and moments. If the current velocity profile is known, the average current velocity can be obtained from the following equation:
|Vc||=||average current velocity (knots)|
|T||=||draft of vessel|
|vc||=||current velocity as a function of depth (knots)|
|s||=||water depth measured from the surface|
If the velocity profile is not known, the velocity at a known water depth shall be adjusted by the factors provided in Figure 31F-3-2 to obtain the equivalent average velocity over the draft of the vessel.
