Abstract

Based on the real design parameters and environmental load, PLAXIS Monopile Designer and SACS software were used to realize the optimal design of reduced monopile in a wind field of China. The ultimate strength, structural deformation, natural vibration frequency and fatigue analysis were carried out. The reduced monopile with the same upper size had a larger mud surface angle and horizontal displacement, and a lower vertical displacement and natural vibration frequency. The results verify the feasibility of the reduced monopile scheme, and achieve a 10.9% reduction in steel consumption.

Key words
