The offshore jacket structure has the advantages of suitable stiffness; convenient construction; anti-collision; and strong fatigue resistance; and it is the main structural form of offshore converter station. By constructing a numerical wave tank for the hydrodynamic response analysis of the offshore jacket structure; the wave field distribution around and the wave slamming load on the offshore jacket structure for the converter station under the action of waves are analyzed based on the Star CCM+ software 2206. In addition; the effects of wave height and wave period on its hydrodynamic loads are discussed. The results indicated that: (1) A thin jet layer can be formed on the wave-facing side of the square box when the waves attack the box; and the height of the jet is not the maximum when the horizontal load generated by the jet at the front of the box reaches the maximum value. (2) The pressure distribution on the wave-facing side of the square box for the converter station is relatively discrete; with the pressure in the middle part being slightly larger than that on both sides. At the bottom of the box; the pressure in the middle and back part is significantly larger than that in the front part. (3) When the waves attack the box for the converter station; it caused significant energy dissipation; and the horizontal load on the offshore jacket is less than that when no wave slamming occurs. © 2024 by the authors;
