Effect of Fin Area and Contorol Methods on Reduction of Rool Motion with Fin Stabilizers

JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1993
This paper discusses some investigations on the influence of the fin area of a fin stabilizer and the control method on the reduction of roll with the fin stabilizer in view of full scale test results. In order to select the optimum fin area, it is important to use not only empirical wave slope capacity, but simulation including rolling probability ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

The Pontoon Design Optimization of a SWATH Vessel for Resistance Reduction

Journal of Marine Science and Engineering
This study applies a deep neural network (DNN) to optimize the 22.5 m pontoon hull form of a small waterplane area twin hull (SWATH) vessel with fin stabilizers, aiming to reduce calm water resistance at a Froude number of 0.8 under even keel conditions.
