Vibration Control of Offshore Platform Based on Outrigger Damping System

Abstract:

Outrigger damping system is used in JZ20-2 north high wellhead platform, making simulation analysis to the whole structure subjected to pushing ice load by finite element software ANSYS, calculating displacement and acceleration response under different length of horizontal pole and different height of damper. The height of the damper has great influence on displacement and acceleration. The damping effect of horizontal bar length has an impact on the damping system, and the main influencing factor is the damper height, and when the height is H2 the damping effect is the most ideal.
