A review of the researches on the added mass and damping coefficients for the heave plates of the offshore platforms at translational and rotational oscillations

In recent years, using the offshore platforms in deep water locations is increasing for extracting oil and renewable energy. In such places, the harsh environmental forces of wind and sea waves cause vibration and instability for the structure. One of the optimized solutions for the reduction of vibration is installing the heave plate at the end of the platform column. These plates induce damping and added mass in motion equations of the structure. Therefore, deriving of the hydrodynamic coefficients is a requirement for obtaining the platform response accurately. The present paper is a comprehensive study on published researches and computational methods of the hydrodynamic coefficients and their corresponding effective parameters in a classified order. In the following, the drawbacks are pointed and new suggestions for future research are expressed.
