[0003] Unlike land-based photovoltaics, offshore photovoltaics often use large-span module structures in order to effectively reduce the workload of offshore operations. However, even so, an offshore photovoltaic project still needs to complete the construction of up to thousands of photovoltaic modules and tens of thousands of structural support piles. Offshore construction is a high-risk, high-investment engineering operation. During the operation, it is affected by the marine environment, such as wind, waves, and currents. The construction ship is always in a swaying state, and the lifting machinery and piling equipment cannot be completely still, resulting in deviations in construction accuracy, positioning dimensions, etc.

[0004] In addition, offshore photovoltaics require a huge amount of piling and hoisting construction. Completing each pile foundation, module precision adjustment and tolerance during the construction phase will greatly increase offshore operation time and reduce engineering operation efficiency.
