Abstract

Abstract

Offshore wind power， as a key field of renewable energy in China， is of great strategic significance. Currently， two primary methods are used in the design phase： integrated analysis and traditional iterative analysis. Given the high cost of offshore wind power units， selecting an appropriate design method is crucial. In this paper， the fatigue loads and dynamic responses of the monopile foundation and the jacket foundation for a 5 MW offshore wind turbine were compared using both the integrated and traditional iterative analysis methods. The results showed that integrated analysis effectively reduced fatigue damage in both the monopile foundation and the jacket foundation， thereby decreasing their steel material consumption. Differences in the bottom bending moment of the monopile foundation and the base shear of jacket foundation legs between the integrated and traditional iterative analyses were compared. The results indicated that the discrepancies between the integrated and traditional iterative analyses were mainly attributable to the interaction of wind loads and wave loads.
