## The Management of Merchant Ship Stability Trim & Strength

Conditions of stability hull strength draft and trim of. A ship or any other freely floating body displaces its own weight of the liquid it is in when afloat. This weight (w) acts downward through the center of gravity of the body (G) and is resisted by an upward buoyant force (equal to w), which acts through the center of buoyancy (B) (see Figure C-1, As the trim and stability calculations are made, this information is transferred or filled in on the pro-forma. An example showing the steps in this procedure is provided. The chapter provides a list of nomenclature of various ship terms. Some photographs of merchant ships are also provided.

Chapter 1 5 What is stability? Stability is a measure of the vesselвЂ™s ability to get back on an even keel after having suf - fered a heel. Different factors affect a vessel, Ship Stability Definitions related to Hydrostatic Particulars Density of a substance is its mass per unit volume, normally expressed as tonnes per cubic metre in ship calculations. Relative Density of a substance is the ratio between the density of that substance and the density of fresh water..

Deп¬Ѓnition of Stability Stability is an important concept in linear systems вЂ” we all want to п¬‚y in airplanes with stable control systems! Although many of us have an intuitive feel for the idea of вЂњstability,вЂќ we need a working deп¬Ѓnition that will allow us to classify systems as either stable or unstable. Stability curves and wind-heeling moment lever curves of ships are to comply with the following requirements in Fig.1.2. (1) Heeling angle caused by steady wind is to be less than 16пѕџ or an angle corresponding to 80% of immersing angle of deck edge whichever is less. (2) Area "b" is not to be less than area "a". a b GZ Оёr Оё1 0В° Оё0 в„“w1 в„“w2 Оё2 Оёc Оё Fig.1.2 Stability and wind-heeling
