摘要

The current paper reports the results of a series of small-scale physical model tests conducted to study the marine fouling effects on the wave attenuation/build-up around/inside a 3D floating gravity net cage. The artificial fouling modelled was representative of hydroids, an important fouling organism in the marine aquaculture industry. Regular wave groups with different heights, periods, and steepness were examined. The cage hydraulic response inside and around the cage models was analysed. Changes made by the cage presence to the height, energy flux, geometry and nonlinearity of the waves traversing the cage models were studied. Attenuation of the wave height and energy was observed downstream of the cage models, which grew smaller in the fouling presence and further by the fouling length. Build-ups of the wave height and energy occurred inside the cage models, which grew weaker in the fouling presence and with longer fouling. The fouling effects on the hydraulic response were more pronounced downstream as compared to those inside and upstream of the cage. The experimental data were used to derive nonlinear regression equations, indicative of the primary trends for the wave attenuation/build-up, around/inside the cage.
