Sustainably feeding the growing world population is a major challenge. With 70% of the Earth's surface covered by oceans, the potential of ocean farming is huge. However, the development of offshore aquaculture systems is in its infancy. This paper discusses and presents concept designs for offshore ocean farming, based on collaborative group projects between students at the Stevens Institute of Technology, US, and the University of Southampton, UK. Through the presented concepts and preliminary results, the work highlights the engineering challenges as well as the huge impact sustainable offshore ocean farming can make.
