| Offshore floating photovoltaics face the risk of being damaged by sea ice during winter in the north, and the impact of the iceperiod marine environment on floating photovoltaics is still in the early stages of research. Therefore, it is very necessary to carry outrelevant research. In order to effectively prevent and resist ice, this paper starts with aspects such as hydrodynamic forces, wave impact,support stability, seawater corrosion, and anchoring methods. Firstly, the total environmental load of the photovoltaic array is calculated andsimulated. Then, the containerized floating breakwater, floating array structure, support, accessory materials, and anchoring system areoptimized and designed. Finally, an ice period test is conducted in the coastal waters of Tianjin Nangang, where tidal changes aresignificant. The experimental data and results show that the floating breakwater can effectively block the sea ice outside the cofferdam withthe wave dissipation effect meeting the design requirements, that plastic bolts can not only effectively prevent floating bodies fromloosening due to tides but also resist corrosion from high salt and heavy fog environments, and that the designed anchoring system caneffectively fix the photovoltaic array and make its drift within a controllable range. The research results of this paper provide experimentalbasis and theoretical support for optimizing the offshore photovoltaic technology scheme during ice period in the north. |
