Ship metacenter
Web2 Jul 2011 · A ship of 5000 tonnes displacement enters a dry dock trimmed 0.45 m by the stern. KM = 7.5 m, KG = 6.0 m, and MCTC = 120 tonnes m. The center of flotation is 60 m from aft. Find the effective metacentric height at the critical instant before the ship takes the blocks overall, assuming that the transverse metacenter rises 0.075 m. WebHelp Notes: KG – Height of the ships Center of Gravity the above Keel.. KM – Height of Metacenter above the Keel.. GM – Metacentric Height: This measurement is calculated by subtracting KG from KM (GM = KM – KG).GM is a measure of the ship’s initial stability. A larger metacentric height implies greater initial stability against overturning.

Web27 Aug 2024 · A ship's metacenter (M) is the virtual intersection of two successive lines of action of the force of buoyancy when the ship heels through a very small angle. The initial position of the metacenter is used as a reference in stability calculations. The distance from a ship's center of gravity (G) to its metacenter is known as the metacentric height (GM).
WebWhen a ship floating at rest in still water is inclined by an external force to a small angle fi, the centre of buoyancy shifts from B to the new position – B fi.The point where the new line of buoyancy force intersects the initial line is denoted as the initial metacentre M.
