The Code contains both mandatory regulations and recommended provisions, setting out the minimum stability standards for ships. [6] This includes information on precautions against capsizing, metacentric heights (GM), righting levers (GZ), rolling criteria, Free surface effect and watertight integrity.

The Code covers specific ship stability requirements for grain ships to prevent dangerous stability from the shifting of grain. [1] [3] Ships are required to be issued with a Document of Authorisation (SOA) and a Grain Loading Manual. [1]
The stability conditions of watercraft are the various standard loading configurations to which a ship, boat, or offshore platform may be subjected. They are recognized by classification societies such as Det Norske Veritas , Lloyd's Register and American Bureau of Shipping (ABS).
The metacentric height is an approximation for the vessel stability at a small angle (0-15 degrees) of heel. Beyond that range, the stability of the vessel is dominated by what is known as a righting moment. Depending on the geometry of the hull, naval architects must iteratively calculate the center of buoyancy at increasing angles of heel.
An inclining test is a test performed on a ship to determine its stability, lightship weight and the coordinates of its center of gravity.The test is applied to newly constructed ships greater than 24m in length, and to ships altered in ways that could affect stability.
Simpson's rules are a set of rules used in ship stability and naval architecture, to calculate the areas and volumes of irregular figures. [1] This is an application of Simpson's rule for finding the values of an integral, here interpreted as the area under a curve. Simpson's First Rule
The Cape Town Agreement defines minimum requirements on the design, construction and equipment of fishing vessels. [1] It also includes details for the inspection of fishing vessels, as well as mandatory requirements for ship stability, seaworthiness, life-saving appliances, fire safety, ventilation and communication equipment.
