  •   [Introduction]  In offshore wind power project, it is necessary to test the pile at sea, which can further optimize the design of pile foundation and provide construction parameters for large scale pile sinking. In recent years, with the increasing capacity of the offshore wind turbine assembly machine, and the sea wind field site continues to move towards the deep water area, in order to meet the bearing requirements, the length of the steel pipe pile in the foundation of the offshore wind power is increasing. Compared with the ordinary test pile, there are many differences in the test pile of super long steel pipe pile. To ensure the offshore super long steel pipe pile is to achieve the desired goal,
      [Method]  the key technology of offshore pile test was discussed in depth. The paper first discussed the setting of test items for super long steel pipe pile test,
      [Result]  and determined the reasonable sequence of test piles. Then the paper analyzed the key technologies of super long steel pipe pile test pile, such as datum pile setting, counterforce device, pile driving construction, scour monitoring, pile protection and sensor protection for pile body,
      [Conclusion]  which has guiding significance to the offshore super long steel pipe pile test project in the future; Finally, the future development and prospect of offshore pile testing project is summarized in this paper.
