On September 10th, China’s first wave-resistant deep-sea floating hexagonal truss photovoltaic platform – “ Huanghai I” was formally delivered.
The platform is jointly developed and designed by China National Offshore Engineering Equipment Technology and Huaneng Clean Energy Research Institute (HCERI), and constructed by China National Offshore Equipment Technology as the construction contractor.
It is reported that the platform has solved the problem that the upper photovoltaic module and electrical system are easily damaged by the wave thumping, and it can withstand the bad sea condition of the area where it is located for 50 years.
The “Yellow Sea No. 1” platform has a side length of more than 25 meters, an area of about 1,624 square meters, weighing more than 360 tons, which is equivalent to the size of four standard basketball courts, an overall height of 9 meters, and a height of 7.5 meters above the sea surface, which ensures that the waves can never come up to the photovoltaic platform under extreme sea conditions.
The platform innovatively adopts a hexagonal design and truss structure, with buoyancy provided by 64 plastic blocks, which can effectively reduce the weight by about 25% compared with traditional offshore PV platforms.
The platform is mainly used to carry out tests on the wind and wave resistance, durability, maintainability, module power generation performance and weather resistance of floating offshore PV platforms.
