In this paper, AMD control strategies are proposed to control the vibration of offshore platform structures induced by ice force and earthquake. Against the background of JZ20-2MUQ platform, the parameter optimization for AMD control system is conducted, which contains both soft parameter and hard parameter for the system, and the time domain simulation for the structure with the optimized AMD control system in several representative work cases of ice and earthquake affairs is also incorporated. As a result, some qualitative and quantitative conclusions are drawn, which provide a necessary foundation for the practical engineering design. The proposed active AMD control methods in this paper are referential to the control issue of other similar offshore platform structures.
