PURPOSE

The stabilizers are designed for roll reduction, when a ship is going ahead. The stabilizers make better mechanisms, devices and equipment operation conditions, increase efficiency of special devices as well as livability for a crew.

The stabilizers can be installed aboard ocean-going ships of various purposes.

The stabilizers ensure the specified efficiency of roll reduction within the range of ahead speeds from 5 to 32 knots.

DESIGN

The stabilizer operates automatically in a watch-free space, requiring only periodic inspection and lubrication of friction units.

The stabilizer is controlled remotely from an external post.

The stabilizer is a complicated mechanism including:

  • working parts with non-retractable or retractable fins;
  • electrohydraulic fin-tilting gears (mechanisms of power drives);
  • control system.
