Energy storage technology is one of the important means to address the impact of large-scale offshore renewable energy grid integration on grid security. In recent years, gravity energy storage(GES) technology has attracted widespread attention. To apply this new type of energy storage technology to the ocean, this paper proposes a novel offshore GES support structure based on the foundation of wind turbine jacket structures, according to the structural characteristics of the new GES system. To verify the feasibility of the support structure, it is proposed to construct it in a certain sea area. Based on the hydrogeological conditions of the sea area and the data of wind turbine units, the preliminary dimensions of the structure are determined. A finite element model is established using SACS software based on the structural dimension parameters, and static and modal analyses are performed to check whether the structure meets the requirements for strength, deformation, and frequency. According to the calculation results, all requirements are met, preliminarily verifying the feasibility of the structure.
