All limiting values
for the responses were based on standard design limits for helicopter
operations. |
|
All values are given
in terms of significant single amplitudes; i.e., the average of the highest
one-third of all values in the random process. |
|
Responses considered
were ship’s roll and pitch, the vertical velocity at the ramp location as
well as the relative motion between the ramp’s lower point and the sea. |
|
This relative motion
can be used to calculate the expected number of wetness events in a random
sea, and it depends heavily on the vertical location of the lower point of
the ramp. |
