Forces/Moments. Methods in Chapter 4, as well as data in NFESC
Report TR-6003-OCN, are used to compute the forces and moments on the ships.
These values are summarized in Figure 8-13. Wind angles are based on the local
coordinate system for a ship shown in Figure 4-2.
Note that wind tunnel model tests show that there is significant sheltering
in the transverse direction of downwind ships in this nest of identical ships, as shown in
NFESC Report TR-6003-OCN. However, there is little wind sheltering in the
longitudinal direction. Table 8-4 summarizes the environmental force calculations used
for this example.
