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.
5 Απρ 2021 · The next article will discuss the basic concepts of ship stability which includes an introduction to intact stability and damaged stability, with detailed understanding of evaluation of intact stability of a ship along with various cases that affect the same.
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.
9 Ιαν 2021 · A thorough knowledge on curves of intact stability can help us know and analyse real cases of instability caused in surface ships. For each case of instability, a ship designer must first know the effect it would cause on the ship.
Free guide to ship and small vessel stability. Aimed at small vessel users but suitable for professional mariners. Diagrams, text and animations explaining stability: from righting lever to movement of liquid in tanks – the free surface effect. Demonstrates adding weights to a vessel, heel and list.
From this curve it is possible to get following: > GZ value of any angle of heel. This can be used to find moment of statical stability at any given angle of heel. Righting Moment (t-m) = GZ x Displacement of the ship.
The curve shows the stability of the ship at all heeling angles (usually up to 90°). The curve of the righting arms applies to a specific draft and weight distribution. The righting arm must be sufficiently large at each angle for the ship to right itself various conditions such as bad weather.
