  • 1

    What is the point which all the vertically downward forces of weight are considered to be concentrated the center of the mass of the vessel?

    center of gravity

  • 2

    What do you call a centrifugal force act horizontally on the center of gravity of the ship, in a direction opposite to that of the turn. This force is balanced off on the underwater part of the hull in the opposite direction?

    hydrodynamic pressure

  • 3

    What do you mean of a weight per unit volume of a substance?

    Density

  • 4

    What is distance from the center of gravity to the meta-center or metacentric height?

    gm

  • 5

    What is the meaning of Trim

    Is the difference between Forward & Aft draft

  • 6

    What is the cause of Internal Heeling moments of the vessel?

    Moving of weight athwartship

  • 7

    The point at which buoyant forces act vertically upwards?

    Center of buoyancy

  • 8

    A vessel is said to be heeling when the upsetting moments are caused by external agents, except.

    Free Surface affect

  • 9

    What is GM?

    Mathematical distance from Center of Gravity to Metacenter

  • 10

    What method is the assumptions considered in this method are that the flooded compartment does not provide buoyancy anymore and hence, there is no change in displacement or KG of the vessel and no free surface effect is observed?

    Lost buoyancy method

  • 11

    What affect the vessel ‘s list?

    Asymmetrical cargo onboard

  • 12

    What is the correct intact stability requirement?

    Initial GM or metacentric height should not be less than 0.15 m.

  • 13

    What happens to metacentric height when vessel is in unstable equilibrium caused by external force applied and will cause her to start heeling, the vessel has?

    Negative metacentric height

  • 14

    The changes in draft and stability when a compartment becomes flooded due to damage can be investigated by either of two methods: What method has IMO/SOLAS recommends to use for computing final draft, trim & righting moment?

    Added weight method

  • 15

    What is a traditional method of assessment of the stability of a ship when it is flooded and is divided into several subdivisions along its length with the help of transverse watertight bulkheads?

    Deterministic damage stability
