This report describes the results of a hydraulic model test
carried out to study the effectiveness of the proposed South Yard
pier in sheltering a submarine, two APL models, and a YRBM model
from wave action. Various types of wave screens were also tested.
The submarine model was found to be very stable in waves with
periods ranging from 2.8 seoonds to 8.2 seoonds with no wave screen.
In fact, no screen tested in the study was found to contribute
significantly to the stability of the submarine.
The existence of the proposed pier alone reduced the amplitudes
of pitching, rolling, and heave oscillations of an APL model by
roughly 50 percent. A submarine model moored to the pier reduced
the oscillations of an APL by another 50 peroent.
