Abstract: I have designed a floating cage based on a trimaran ship model. The floating cage has been built with naval steel, and it’s formed by four floats joined by a steel structure. The weather deck is over this structure with a small control room in the middle of the stern top. This deck allows workers to be able o operate with the kiddles, feeding the fish and controlling the ship with ample workspace. The floating cage has been designed to sail short distances and to operate near the coast with good weather. There are many studies which show floating cages sink into the Cádiz bay because of the winter storms, that’s why my cage was designed to be used during spring and summer, between February and November. At the stern bottom it has two azimuth propellers, on per side, to propels the floating cage. It’s not necessary to install a rudder because this kind of propulsion can turn round by themselves, so the ship can maneuver easily too. For the size I have calculated the number of cubic meters needed to farm enough fish, to make the floating cage efficient. The first factor is the OGD (Optimum Growing Density) of the sort of fish we are going to farm. In these case, We are going to grow Sea Breann and Sea Bass, that has a OGD like 4Kg/m^3. The second factor is the survival ratio of the fingerblings (baby fish). With these two factors I have calculated the volume of water used to farm the fish, and these volume is used to sized the main dimensions. The four floats have to support their own weigh, the weigh of the structure, the machinery, the joining structure, the first floor, the workers the fish the kiddles and the fish food.
