N2 - The demand for fish and algae products is increasing continuously while the production from direct, worldwide fisheries stagnates. The stagnant sea-fishing amounts are compensated to a significant degree by aquaculture production where in contrast growth rates are much better predictable. Another possible countermeasure to bridge the sea food supply gap arises when a co-use of aquaculture and offshore wind energy structures are taken into account. This idea has the advantage that existing support structures in a high nutrition environment could be utilized. In the present study the manifold interactions between such an aquaculture fish cage and a tripile foundation are investigated by means of physical model test in a length scale of 1:40. A first aspect of the analysis comprises the change of wave induced particle velocity and its distribution around the support structure due to the fish cage. Secondly, the central focus remains obviously the additional forces exposed to the tripile as a result of the additional fish cage bearing by means of force measurements under monochromatic waves. Finally the additional effects to potential scour around the tripile are also investigated. The sea state at the location of interest is approximated with monochromatic waves for a mean event and an event with 50 yearly exceedance probability.
