Abstract

This study is to investigate the overall risk probability of the bucket foundation during the construction period. To achieve the above purpose, the risk sources were first identified. Then, the risk index system of the bucket foundation during the construction period was further constructed. Finally, an improved fuzzy fault tree analysis method was employed to quantify the overall risk probability of the bucket foundation and monopile foundation. The results obtained by the proposed method in this study show that the risk probability of the bucket foundation and monopile foundation is 3.21×10^-3 and 9.47×10^-3, respectively. According to DNV specification, both the risk probability of the bucket foundation and monopile foundation during the construction period falls into the high-risk level range, and the latter is 66.10 % higher than the bucket foundation. We can conclude that the bucket foundation is relatively safe during the construction period and has preferable engineering practicability.
