Development of a New Type of Ship Anti Rolling System

Abstract

For ocean going ships, some times anti rolling systems are indispensable for carrying out her mission or obtaining comfortable life at sea. Those ideas for anti rolling were mostly proposed during the end of 19th century. Among those, bilge keels, anti rolling tanks and weight stabilizers are used until today. Those anti rolling systems use damping system by energy dissipation or motion or force compensation system. Opposite to those existing ideas, here, we proposed a new anti rolling system for high speed container ship, using anti moment by wing stabilizer and gyradius stabilizer and these idea were confirmed by numerical simulations and model tests.
