Reduction of Offshore Platform Dynamic Response by Tuned Mass Damper

Abstract

An investigation of a tuned mass damper for reduction of offshore oil platform motions is conducted using finite element tower models disturbed by discretized wave spectra. Vibration control principles and their application to offshore oil platforms are discussed. Changes in system response are examined as damper parameters are varied. Response reduction and damper mass motion are found to be coequal design considerations. An assessment is made of a tuned mass damper's effectiveness in reducing the effects of increasing the natural period of offshore platforms, fatigue in steel-jacketed platforms, and soil-degradation under gravity platforms.
