Active Fin Stabilizers

The operating of a cargo or cruise ship are affected by the motions and forces due to rolling, which can cause ship/cargo damage and discomfort to the crew and passengers. In naval vessels, heavy rolling may affect the accuracy of the weapon system or prevent the landing or take off of helicopters or airplanes. In severe sea conditions, rolling may make it necessary for a ship to deviate from her planned course to avoid the rough sea with consequent loss of time and money. Different kinds of devices, known as stabilizers, have been developed for the purpose of reducing the rolling motion of ships. Stabilizer has become increasingly popular as standard equipment for ships, especially on passenger/ vehicle carrying ships, on certain classes of warships and yachts. In general these appliances are of the passive or of the active type. Active fin stabilizers are fins mounted beneath the waterline and emerging laterally. An active stabilizer has present control whereby the corrective action in the form of a counteracting movement is programmed to take place simultaneously with the occurrence of the disturbing movement that causes the rolling of the ship. In contemporary vessels, they may be gyroscopically controlled active fins, which have the capacity to change their angle of attack to counteract roll caused by wind or waves acting on the ship. The active fin stabilizers are most effective when a ship has relatively high speed (above 10-15 knots), while reduction of ship rolling can be up to 90% by using the generating lift of the fins extended to both sides of a ship. The active fins can be withdrawn into the hull when the ship operates in calm weather conditions to eliminate their small resistance with the water. The active fin stabilizers are able to ensure a drastic reduction in roll with the consequent advantages in terms of passengers and crew comfort ; of ship stability ; of course holding ; etc.
