Recently, the domestically pioneering deep-water foundation pile-surrounding soil reinforcement technology for in-service offshore wind turbines, independently developed by Yongqiang Ocean, was successfully applied at an offshore wind farm in Fujian Province. This marks another key application following the pile-surrounding soil reinforcement technology for deep-water foundations under construction, and signifies the continuous enhancement of Yongqiang Ocean's technological innovation and development application capabilities.

This technology changes the traditional foundation treatment methods limited to land environments and creatively achieves high-precision inclined hole drilling offshore. On this basis, it has developed comprehensive applications of technologies such as offshore low-pressure inclined hole grouting, offshore high-pressure jet grouting inclined piles, and offshore cement mixing piles, and reinforces the soil layer around the inclined pile foundations of in-service wind turbines at offshore wind farms, achieving optimal solidification effects, effectively improving the bearing capacity of pile foundations, and ensuring the safe operation of offshore wind farms. Currently, this technology has been successfully applied in multiple offshore wind farms.

Yongqiang Ocean is committed to becoming a leader in the application and development of offshore geotechnical engineering technology. It currently possesses 5 self-elevating multi-functional platforms, professional drilling vessels and supporting tugboats, offshore drilling rigs, interactive CPTUs, pressuremeters, vane shear apparatus, and other offshore engineering equipment and related construction technologies. It has completed or is implementing more than 20 projects, including offshore deep-water foundation reinforcement.
