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.

5 Απρ 2021 · The concept of hydrostatics and stability can be deemed as one of the most important areas of focus in ship design and operation, not only to ensure the safety of the ship, cargo, crew and passengers, but also to enable proper conditions for completion of all the processes on a ship.
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.
1 Calculate the displacement (Δ) of the ship. 2 Calculate the LCF, LCB, LCG, and KG of the ship. 3 If all compartments (No.1~No.5 for port and starboard, total 10 cargo holds) are fully loaded, with a load whose density is 0.6ton/m3, calculate the deadweight (DWT) and lightweight (LWT).
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.
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.
The IMO is currently in the process of developing performance-based criteria for assessing five dynamic stability failure modes in waves, namely, dead ship condition, excessive acceleration, pure loss of stability, parametric rolling and surf-riding/broaching.
