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.
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).
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.
The graph shown above is a stability curve, sometimes called a righting-lever curve or a GZ curve. You will find some of these for your vessel in your stability book if you have one.
Quiz NA101. Ship Stability and Geometry – Part 1. Lucas Montogue. Problems. vessel of length 90 m has equally spaced half ordinates of the waterplane as follows, commencing from the after perpendicular. Find the area of the waterplane. A = 205 m2. A = 307 m2. A = 409 m2. A = 504 m2.
In Chapter 4 we will study five areas: The concept of a ship’s Righting Moment (RM), the chief measure of stability. KG and TCG changes and their effects on RM. How Stability is effected by Damage to the Hull using the “Added Weight” method. Effects of a “Free Surface”. Effects of Negative GM on ship stability.
Tables and diagrams of cross curves (NKsin (φ) tables). Bonjean tables. Deadweight tables and deadweight scale. Tables of wind heeling moments. Tables and diagrams of maximum allowable Vertical center of Gravity (VCG'), for intact as well as damaged ship. Floodable length curves.
