WebMetacentric height also has implication on the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers. Hence, a sufficiently high but not excessively high metacentric height is considered ideal for passenger ships. The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning. The metacentric height also influences the … Meer weergeven When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of … Meer weergeven GM and rolling period The metacentre has a direct relationship with a ship's rolling period. A ship with a small GM will be "tender" - have a long roll period. An excessively low or negative GM increases the risk of a ship capsizing in rough … Meer weergeven There is also a similar consideration in the movement of the metacentre forward and aft as a ship pitches. Metacentres are usually … Meer weergeven • Kayak roll • Turtling • Angle of loll • Limit of positive stability Meer weergeven The centre of buoyancy is at the centre of mass of the volume of water that the hull displaces.

This can also be done when a ship or offshore floating platform is in service. It can be calculated by theoretical … Meer weergeven
WebMetacentric height mainly depend upon the shape od volume displaced by the ship when it goes under some disturbance in any of the direction, since the rotation of the ship about the three axis will displace different amount of water, therefore in different direction the position of metacentre will also change.
