Inspection of stability of a general roll-damping of a ship via non-perturbative approach.

ABSTRACT: The current study explores nonlinear stability in vessels with roll-damping to ensure safety in realistic maritime conditions, thereby expanding stability. It develops a generalized model that considers operating situations, nonlinearities, and hydrodynamic factors. One degree of freedom (1DOF) of nonlinear ship dynamics is included in the exiting model. The prototypical incorporates inertia, damping, restoring forces, and external forces. The objective is to examine the responsible non-perturbative method (NPA) in determining periodic response of a damped and conservative coupled system. In contrast to all other traditional perturbation techniques, NPA's goal is to convert a weakly oscillator of nonlinear of ordinary differential equation (ODE) into a linear one without consuming Taylor e
