In accordance with the present invention, an oscillation suppression system is
provided to inhibit vertical and rotational resonance of a floating platform. The
oscillation suppression system includes energy absorption chambers mounted in or
about the hull of the floating platform. The chambers may be separately attached
or integrated as part of the structure. The chambers are comprised of gas in an
upper portion, and water mass in a lower portion. The chambers are closed or partially
vented at the upper ends and open at their bottom ends. The enclosed gas in the
upper portion of the chamber acts as a gas spring reacting against the floating
platform and the water mass. The suppression of resonant oscillations of the floating
platform system is accomplished through the gas-spring pressure changes acting
on the floating platform system in phase opposition to external forces.
