Research on Vibration Control of Offshore Platform Based on Self-Recentering Rocking Wall

Abstract:

Self-recentering rocking wall is used in JZ20-2 north high wellhead platform, making simulation analysis to the whole structure subjected to ice load and earthquake load by the finite element software ANSYS, then analyses the nodal displacement and acceleration responses under the condition of different platform rocking wall stiffness, different floating box’s location, different buoyancy case. The results show that stiffness is the main factor affecting the seismic performance of offshore platforms, floating box can effectively reduce the dynamic response of offshore platform.
