Design and Model Testing of Aquaculture Net-Pens
To provide low cost, effective and reliable offshore net-pens to commercial fishermen. To meet this objective, it is necessary to carry out finite element and reliability analysis early in the design process to optimize offshore net-pen design.
The ultimate success of the proposed research hinges on the hypotheses that the dynamic response of offshore net-pens can be adequately modeled by the finite element method, and that the design life of offshore net-pens can be predicted using experimental and numerical techniques.
The dynamic response of offshore net-pens will be obtained by the finite element method. To predict the fatigue life of offshore net-pens, the Monte Carlo method will be employed.
In the development of the commercial aquaculture industry, the task of designing offshore net-pens for finfish, such as cod and haddock, is very difficult due to the complex wave and current loading to which these structures are subjected. Net-pen design has developed over the years mostly by trial and error and through the construction and testing of prototypes. Because this is very expensive and time consuming, analytical or computer based models are needed to evaluate design criteria such as reliability and dynamic response before prototypes are built.
