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

نشریه مهندسی دریا, 2020
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.

Experimental Study on Hydrodynamic Characteristics of Streamlined-Layout Double-Row Floating Breakwaters with Wing Plates

Journal of Marine Science and Engineering
Floating breakwater layouts require flexible adjustment to accommodate sheltered area bathymetry. However, most studies have focused solely on straight layouts and have neglected the influence of complex nearshore bathymetry and structures.

Effect of Viscous Damping on Hydrodynamic Response of Spar with Heave Plate

Aquatic Procedia, 2015
Abstract In the present paper, effect of viscous damping on the heave response of spar is studied using WAMIT software for spar with single and two heave plates. For spar with single heave plate, a plate is attached at the keel of the spar and the diameter of the heave plate is varied.

Set-Point Algorithms for Active Heave Compensation of Towed Bodies

, 2016
Active heave compensation is a technique used in marine applications to attenuate undesirable wave motions between a load and its host vessel. Motion attenuation is often achieved by reeling in or reeling out a cable tethering the load to the host vessel
