  2. Stabilizer (ship) - Wikipedia

    en.wikipedia.org/wiki/Stabilizer_(ship)

    In 1915 the gyroscopic stabilizer was mounted on US destroyer USS Worden (DD-16). [4] The World War I transport USS Henderson, completed in 1917, was the first large ship with gyro stabilizers. It had two 25-ton (23 t), 9-foot (2.7 m) diameter flywheels mounted near the center of the ship, spun at 1100 RPM by 75 HP AC motors. The gyroscopes ...

    The World War I transport USS Henderson, completed in 1917, was the first large ship with gyro stabilizers. It had two 25-ton, 9-foot (2.7 m) diameter flywheels mounted near the center of the ship, spun at 1100 rpm by 75 hp (56 kW) AC motors. The gyroscopes' cases were mounted on vertical bearings.

  4. Ship stability - Wikipedia

    en.wikipedia.org/wiki/Ship_stability

    Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity , centers of buoyancy , the metacenters of vessels, and on how these interact.

  5. Gyroscopic stabilizer - Wikipedia

    en.wikipedia.org/wiki/Gyroscopic_stabilizer

    A Gyroscopic stabilizer is a control system that reduces tilting movement of a ship or aircraft. It senses orientation using a small gyroscope, and counteracts rotation by adjusting control surfaces or by applying force to a large gyroscope. It can be: Some active ship stabilizers adjust "active fins" of the ship or apply force to a large ...

  6. Antiroll tanks - Wikipedia

    en.wikipedia.org/wiki/Antiroll_Tanks

    Antiroll tanks are tanks fitted onto ships in order to improve the ship's response to roll motion. Fitted with baffles intended to slow the rate of water transfer from the port side of the tank to the starboard side and the reverse, the tanks are designed such that a larger amount of water is trapped on the higher side of the vessel.

  7. International Code on Intact Stability - Wikipedia

    en.wikipedia.org/wiki/International_Code_on...

    The Code contains both mandatory regulations and recommended provisions, setting out the minimum stability standards for ships. [6] This includes information on precautions against capsizing, metacentric heights (GM), righting levers (GZ), rolling criteria, Free surface effect and watertight integrity.

  8. Metacentric height - Wikipedia

    en.wikipedia.org/wiki/Metacentric_height

    Ship stability diagram showing centre of gravity (G), centre of buoyancy (B), and metacentre (M) with ship upright and heeled over to one side. As long as the load of a ship remains stable, G is fixed (relative to the ship). For small angles, M can also be considered to be fixed, while B moves as the ship heels.

  9. Elmer Ambrose Sperry - Wikipedia

    en.wikipedia.org/wiki/Elmer_Ambrose_Sperry

    [6] [8] His gyroscope-stabilized ship differed from others at the time by having a sensor built in to the system to detect the first signs of a wave that the system would have to work to mitigate. [8] In 1911, Sperry worked with the US Navy to incorporate his gyroscopic stabilizer, which greatly reduced major roll of the ship, into Navy ships. [8]
