Stability of Floating Bodies in a Stochastic Seastate

Abstract

The development is proposed of new methods for the modeling of the nonlinear responses, stability and control of ships and wave energy converters in a stochastic seastate. The radiation and diffraction hydrodynamic forces exerted upon the floating body by ambient irregular waves and their responses will initially be cast in state-space form by implementing the ESPRIT algorithm. This will enable the study of the stability and control of floating bodies in stochastic seastates by invoking the methods of stochastic differential equations. Moreover the state-space representation of the system responses will enable the use of standard control methods for the enhancement of energy capture of wave energy converters and the optimal and safe operation of ships in severe weather environments.
