Abstract

In India, experimental offshore cages for mariculture have been installed at several sites along the Indian coast. Some of them have been commercially successful while some have faced technical difficulties. Modification in the cage design has been done mostly by trial and error method to suit the local conditions. For designing the cage, tensions in the mooring chain and fish net twine are to be estimated. In the present study, we have presented a six degree of freedom model for a single point mooring cage and tried to study the various motions of the cage. The tensions in the mooring chain and the various forces acting on prototype cage were predicted based on the numerical simulation. The predicted values are comparable with the values published by other researchers. This information will be useful for our future prototype measurement and design work.
