Damping Characteristics of Heave Plates Attached to Spar Hull
Volume 1: Offshore Technology, 2012Damping elements are used in ships and offshore structures as response reduction devices for maintaining the hydrodynamic response within acceptable limits. The use of such elements so far has been based on past experience or using empirical based design approach.

Response Analysis of a Truss-Pontoon Semisubmersible With Heave-Plates
Journal of Offshore Mechanics and Arctic Engineering, 2005An offshore platform that is efficiently designed to reduce the wave excitation forces and increase the separated-flow damping could qualify as a platform operating even near its resonance. Such design could make this concept cost-effective, as well as operationally more productive with minimum downtime.

Parametric Optimization of a Semi-Submersible Platform With Heave Plates
Volume 1: Offshore Technology; Special Symposium on Ocean Measurements and Their Influence on Design, 2007The hydrodynamic responses of a semi-submersible platform are driven by its mass properties and geometric parameters, e.g. column size, spacing, draft and pontoon size. The mooring system also influences the platform responses. Heave plates added to the base of each column have been proposed to enhanced stability of semi-submersible platforms ...

Vortex Flow Behind a Heaving Elastic Flat Plate
Volume 1: Symposia, Parts A and B, 2008An unsteady flow in a low Reynolds number region attracts attention in recent years. Various experiments/numerical analyses have been conducted in wake flow fields of objects with unsteady motions in low Reynolds number regions have been studied and reported recently.

Engineering Structures, 2018
Abstract The undesirable motions resulting from wave loading can lead to the long-term fatigue damage or even catastrophic sinking of offshore semi-submersible platforms (SSP). It is therefore by all means necessary to suppress the excessive vibrations of SSP. Many methods have been proposed to mitigate the heave motion of offshore platforms, such as

Deepwater offshore structures such as semi-submersible platforms suffer powerful ocean waves due to their location and site condition. The long distance away from the shore also brings many difficulties to energy supply for the platform operation.

Experimental Study on the Suppression of a Vertical Circular Cylinder with a Heave Plate
New & Renewable Energy, 2016Studies of floating structures are becoming increasingly important due to their increased application. The hydrodynamic motion response of floating structures must be controlled within a certain range, especially in the resonance region. In this study, a scale model of a circular cylinder having a height of 300 mm, outer diameter 60 mm, natural heave ...

Analysis on Schemes of Passive Heave Compensation System for Base Plate
Advanced Materials Research, 2012Three kinds of schemes of passive heave compensation systems (PHCS) for base plate are presented in this paper. These schemes are PHCS based on winch, PHCS based on weight and PHCS based on hydraulic cylinder. An analysis focused on the principles and the characteristics of these schemes is developed, and the hydraulic systems of these schemes are also
