Abstract
The design of monopile foundations for offshore wind turbines involves multiple disciplines and faces the challenges such as uncertainty, non-uniformity of the design standards, and low computational efficiency. Focusing on the Jiangsu sea area, an integrated design approach was used to compare conventional verification methods, including API-WSD and ISO standards, with a new verification method that combines the fourth strength theory with European standards. The primary aim was to analyze the differences between the old and new verification methods for monopile foundations. By statistically analyzing the geometric parameters of 17 monopile foundations from different wind farms, the study investigated the relationships between mudline loads, pile diameter, and pile length. This led to the establishment of a relationship curve between load, geometric dimensions, and weight. As a result, a rapid evaluation method for monopile foundation design was proposed, and an intelligent rapid evaluation platform was developed.
