| Description |
This was an experimental
investigation of the refraction of surface waves from a localized area of the open ocean
for purposes of launching and retrieving divers and submersibles as well as smoothing
water where divers are working. |
| Progress |
Complete. Towing tank experiments
were conducted in regular, oblique, and random waves using towed turbulence grids. For
regular waves, dramatic wave attenuation can be obtained at modest power requirements for
wave periods up to six seconds. Results for oblique and random seas require much more
power, but are still encouraging. Full scale trials were conducted revealing wave
attenuation, but because of fairly calm seas, tests should be rerun, at quarter scale. |
