Optimal design on ship synthetic stabilizer system based on fin stabilizer and anti-rolling tank

For some ships in special use or the warships as sea platforms, the out range rolling will produce bad effects on the operation of the ships or the equipments on the warships. The current researches show that the synthetic stabilization scheme combined several stabilization sets is the main trends in the future. Considering the relationship between fin stabilizer and passive ling tank and the stabilization effectiveness in all kinds of sea condition, a configuration scheme of fin stabilizer and passive anti-rolling tank is proposed. An index of function-effectiveness is defined according to the economic factors. The simulation shows that the scheme employing low-capacity fin stabilizer to match anti-rolling tank is more rational.
