摘要：
To address the boom slamming problem of offshore platforms, based on the impulse theory of water entry slamming, in this paper, we propose a numerical simulation model comprising three couplings of the structure, water, and air for studying the relationship between slamming load and water entry angle and velocity on the semi-submersible platform column. We also discuss the spatial distribution of the slamming pressure on the water entry surface. Our results show that the slamming pressure is closely related to both the water entry angle and the spatial position of the water entry surface. We also found the speed of the entering water to have some influence. Our numerical calculation results can be used to rapidly predict the slamming load on a column, which can guide safety evaluations of platform column structures in practical engineering projects. © 2019, Editorial Department of Journal of HEU.
