  2. 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.

  3. Metacentric height - Wikipedia

    en.wikipedia.org/wiki/Metacentric_height

    Criteria for this dynamic stability effect remain to be developed. In contrast, a "tender" ship lags behind the motion of the waves and tends to roll at lesser amplitudes. A passenger ship will typically have a long rolling period for comfort, perhaps 12 seconds while a tanker or freighter might have a rolling period of 6 to 8 seconds.

  5. Stability conditions - Wikipedia

    en.wikipedia.org/wiki/Stability_conditions

    The stability conditions of watercraft are the various standard loading configurations to which a ship, boat, or offshore platform may be subjected. They are recognized by classification societies such as Det Norske Veritas , Lloyd's Register and American Bureau of Shipping (ABS).

  6. Naval architecture - Wikipedia

    en.wikipedia.org/wiki/Naval_architecture

    Longitudinal stability for longitudinal inclinations, the stability depends upon the distance between the center of gravity and the longitudinal meta-center. In other words, the basis in which the ship maintains its center of gravity is its distance set equally apart from both the aft and forward section of the ship.

  7. Angle of list - Wikipedia

    en.wikipedia.org/wiki/Angle_of_list

    The angle of list is the degree to which a vessel heels (leans or tilts) to either port or starboard at equilibrium—with no external forces acting upon it. [1] If a listing ship goes beyond the point where a righting moment will keep it afloat, it will capsize and potentially sink.

  8. Ship measurements - Wikipedia

    en.wikipedia.org/wiki/Ship_measurements

    Lightweight displacement – LWD – The weight or mass of the ship excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level. Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can ...

  9. International Code on Intact Stability - Wikipedia

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

    The 2008 version of the Code details guidelines on Second Generation Intact Stability for ships, specifically criteria for dynamic stability and damage assessment. [7] The Code is split into two parts. Part A contains mandatory criteria. Part B contains additional guidelines and recommendations. [4]
