Roll damping of a surface effect ship with split air cushion
IFAC-PapersOnLine, 2018 Abstract This paper considers linear modeling of a surface effect ship (SES) where roll motions are damped by exclusively exploiting a longitudinally split air cushion design. On a SES, the pressurized air cushions can support up to approximately 80 % of the vessels weight.

Parametric Identification for the Biased Ship Roll Motion Model Using Genocchi Polynomials
Journal of Mathematics, 2022 Roll motion is one of the key motions related to a vessel’s dynamic stability. It is essential for the dynamic stability of ships in the realistic sea. For this research study, we have investigated the parameters involved in damping of the ship.

Design of an Optimal Controller for the Roll Stabilization of Surface Ships with Active Fins [PDF]
Journal of Eta Maritime Science, 2018 In this paper, an optimal controller is designed to control the undesired roll motion of a ship under the effect of sea waves by using active fin stabilizers. The roll dynamics is described by a single-degree-offreedom nonlinear model.
