Read, interpret, and sketch a Curve of Intact Statical Stability (or Righting Arm Curve) and draw the sectional vector diagram of forces that corresponds to any point along the curve.
The light ship value includes weights for spare tailshaft and stowage as given on Sheet 81B ([12821 + 29]/100 = 128.50). Add lines 28 and 29 to obtain line 30 displacement and hogging and sagging numerals for departure and arrival conditions.
3 Ιαν 2021 · The easiest and handiest tool for analysing a surface ship’s stability, is by graphs or curves. A ship designer or an officer on-board should be able to know the stability characteristics of a ship just by looking at the curves. Let's understand curves of static stability of a vessel.
Contents. General particulars. Plan showing cargo spaces, storerooms and tanks. Cargo and tank capacities. Hydrostatic particulars. Tabulated KN values. Maximum KG values. Angle of Heel data. Grain: Full holds and full tween decks, Volumetric Heeling Moments (VHM).
GZ values at different degrees of heeling can be plotted to form a curve as shown below - called a GZ curve. GZ curves give a quick impression of the vessel and its stability.
This „Grain Loading Plan and Stability Booklet“ for this ship has been prepared to enable the master to demonstrate the ability of the ship at all stages of voyage carrying bulk grain to comply with the stability requirements of chapter VI, SOLAS 1974.
Ship Stability and Ship Motion. Stability can also exist in ship structures via the strength of the material from which they are built. A material may be stressed or strained and not return to its initial form, thereby losing its sta-bility. Hence there is a link between Ship Stability and Ship Strength.
