Gyrofin Ship Stabilizer System

Ship stabilizers are fins or rotors mounted beneath the waterline and emerging laterally from the hull to reduce a ship’s roll due to wind or waves.

A gyroscopic control system controls active fins. When the gyroscope senses the ship roll, it changes the fins’ angle of attack to exert force to counteract the roll.

Fixed fins and bilge keels do not move; they reduce roll by hydrodynamic drag exerted when the ship rolls.

Stabilizers are mostly used on ocean-going ships. RKB, as one of the significant Bearing manufacturers, has many successful stories in marine and offshore projects.

RKB developed new bearings to withstand hard maritime applications on sea and ocean.

In this project, the RKB technical team developed customized inch size Double Row Taper Roller bearings (TDO configuration). Bearings’ inner size is up to 670 mm and B10 life for 750,000 movements.
