Abstract
Offshore steel structures are subjected to hydrodynamic forces. These forces induce vibration in the structure, which in turn has a great effect on the safety and durability of the structure and the manpower operating it. Magnetorheological (MR) dampers are proven as a feasible alternative to reducing structural vibrations. This paper presents the initial investigation of integrating MR dampers in Offshore Steel Jacket Platforms to decrease the vibrations discussed. A Steel Jacket Structure with MR damper is simulated using Simulink and the results are presented. In addition, an experimental model is designed to verify the simulation responses.
