The way this is proposed, it sounds as if you are creating a rigid ring. Might I sugest that you use joints that allow flexing with the waves, rather than a rigid structure the fights them? Maybe a tour of the original atoll from “Waterworld” is called for. Their design is wave-tank tested(in scale) for category 5 storms, as is their anchor placement and distribution… It has already survived a number of storms. The only question is if it still exists. It was supposed to go to California, outside that I don’t have any new information. Worth looking in to.
