Abstract:
Introduction Offshore wind power generation is gradually being widely applied in the global energy structure transformation due to its advantages of high annual power generation and stable power generation. However, due to the complex and ever-changing marine environment for offshore wind turbine construction, this poses significant obstacles to the construction process and technical solutions of offshore wind turbine foundations. Method In the context of the construction project of a certain offshore wind farm, this paper analyzed the type selection criteria and feasibility of pile driving construction ships, pile stabilizing platforms and hydraulic pile hammers. At the same time, in response to the construction requirements for wind turbine foundation pile driving, the preparation work before the operation, the construction plan for the pile stabilizing platform, and the wind turbine foundation pile driving operation with the cooperation of the main-auxiliary crane ships were emphasized. Furthermore, the control and correction measures for verticality in wind turbine foundation pile driving were analyzed. Result Steel pipe pile driving construction process can effectively ensure the project quality and expected progress, and has significant economic benefits, safety and reliability. During the pile driving process, it's necessary to complete preliminary and final adjustments to the verticality accural control. Conclusion Through the study of pile driving construction technology for offshore wind turbine foundations, it will provide useful reference and inspiration for similar offshore wind turbine projects.

Abstract:
Introduction With the development of photovoltaics, energy storage, new building materials and prefabricated construction industry, Building Integrated Photovoltaic (BIPV) technology which features the integrated design and manufacturing of photovoltaic modules with components such as roofs, walls and sunshades is evolving as Building Integrated Photovoltaic and Energy Storage (BIPVES) technology. Method The article proposed the world's first rechargeable cement-based battery, promoting the integration of building walls with photovoltaic power generation and storage and discharging devices. Cross-disciplinary innovation was applied to equipment and materials, where high-definition, high transmittance patterned designs were printed on glass surfaces to manufacture high-efficiency photovoltaic building materials. Prefabricated energy storage walls were developed and integrated with various steel-structure prefabricated building systems to achieve customized production and prefabricated construction, leading to a transformative trend of integrating building components with photovoltaics and energy storage. Result Cement-based batteries allow building walls to have multiple functions, including photovoltaic power generation, energy storage and power supply; The new generation of photovoltaic building materials helps save costs on building facade decoration materials and reduce building carbon emissions; The integration of photovoltaics, energy storage and renewable energy technologies in buildings can achieve maximum benefits. Conclusion The new photovoltaic building materials and new energy storage technologies such as cement-based batteries show promising prospects. Combining and integrating rechargeable battery components, photovoltaic exterior panels, prefabricated building walls and embedded parts for widespread application is feasible.
