The overall lifting operation window of the partial block in the 3,000-ton offshore booster station is few and the construction risk is large. Therefore, the research on the split lifting of the upper block is of great engineering significance. Taking an offshore booster station in dalian as the research background, ABAQUS numerical simulation method was used to simulate the effect of upper block split lifting on vertical bearing characteristics of jacket foundation. Research results show that when adopts the split-type hoisting scheme (1) the top settlement of the booster station foundation is smaller than that of the overall loading scheme, but the foundation settlement is not uniform, and the foundation of the booster station has the risk of overturning; The total side friction resistance is smaller than the overall loading scheme, which reduces the stability of the bearing platform. (3) The deflection of the foundation pile body of the booster station is larger than that of the overall loading scheme, which is likely to cause damage to the soil around the pile foundation.
