Optimization of Tuned Mass Damper for Fatigue Damage Mitigation in Offshore Jacket Platforms (Case Study: "Foroozan" and "North Rankin B" Jackets

It is very beneficial to suppress the topside wave-induced vibration of the jacket platforms, as only 15 percent reduction in dynamic stresses, will result in life span of platform to be extendedby 100 percent [1]. In addition, in some offshore oil fields, such as the Persian Gulf, the more influential type of environmental loads is the wave-induced hydrodynamic force. So, many researchers have put their focus on using vibration control technologies for mitigating fatiguedamage due to sea wave excitations. The purpose of this study is to optimize adjustable parameters of tuned mass damper to extend the operational life of offshore platforms by suppressing the fatigue damage
