Abstract: Waves introduce stresses in a floating object, such as a pontoon. The stresses can be introduced by multiple mechanisms, such as waves crashing onto the pontoon, an imbalance in buoyancy and weight load causing hogging and sagging Alternating movements and stresses may result in fatigue in the material. Multiple pontoons can be moored next to each other. When placed on a body of water with a higher wave intensity, such as open sea, the wave induced motions and stresses may cause failures in the pontoons or connections between individual pontoons. A network of pontoons is provided, interconnected with connection modules. The connection modules allow the network of pontoons to resist the loads and movements from the waves or to follow the shape of the, thus preventing failures in the connection modules and in the pontoons. The pontoons may be used to provide a mounting surface for photovoltaic panels.
