Retractable Fin Stabilizers

Main Features

Retractable Fin Stabilizers
  • Accumulated experience and technologies
  • Expert anti-rolling performance
  • High sealing reliability
  • Excellent control system
  • Maintainability
  • Extended roll-sensor working life
Finite Element Method : Finite Element Method has been adopted for verification on thte strength design of the Mitsubishi Retractable Fin Stabilizer.
More comfortable stabilizing through fuzzy control

When the wave period becomes longer than the natural hull roll period, the roll reduction performance decreases, if PID control is used. Fuzzy control can improve the roll reduction performance against these long period waves.


Rapid response in electro-hydraulic system

Each fin is rotated on its axis by a hydraulic cylinder.
Pressurized oil is admitted to the actuators by means of an electro-hydraulic servo valve.
This oil is provided by a fixed displacement pump/off-loading relief valve system.
To achieve rapid movement of the fins, there is a hydraulic accumulator.
