Journal ArticleDOI
A study on the collision avoidance of a ship using neural networks and fuzzy logic
TL;DR: This paper proposes calculation method of the collision risk by using neural network, and MLP (Multilayer Perceptron) neural network to the collision avoidance system is applied to make up for fuzzy logic.
Journal ArticleDOI
Preliminary tests of a damaged ship for CFD validation
TL;DR: In this article, free roll decay tests in calm water with both intact and damaged ships were performed and six degree-of-freedom (6DOF) motion responses of intact ship in regular waves were measured.
Journal ArticleDOI
Design of the roll stabilization controller, using fin stabilizers and pod propellers
TL;DR: In this paper, a MIMO (multi-input multi-output) optimal control system that has two control inputs such as fin stabilizers and pod propellers is designed to reduce the roll motion of cruise ships in regular waves.

TL;DR: In this paper, the authors established an experimental database for CFD validation by collecting data from towing tank tests of a ship hull's 6DOF motion responses in regular waves for both intact and damaged conditions.
Journal ArticleDOI
Hydrodynamic characteristics of X-Twisted rudder for large container carriers
TL;DR: In this article, numerical and experimental results about the hydrodynamic characteristics of XTwisted rudders having continuous twist of the leading edge along the span were compared with those of the semi-balanced rudder.
