Abstract

Field measurement of ship waves has been carried out in Victoria Harbor of Hong Kong. The wave data were collected at 18 monitoring stations by the underwater pressure/current instrument S4ADW and a floating wave rider TYPE 1156. It is found that the wave conditions in the study area are predominantly affected by the ship-generated waves under normal weather conditions. By comparing with the wind-generated waves in the open region which are irregular but with dominant directional characteristics, the existing harbor–wave field is much more complex. The irregular ship–wave field is not statistically stationary. It is also found that the ship–wave spectra are either of multiple peaks or have wide crests without distinct peaks.
