For ship-form shaped vessels, there is an automated mesh generator that works from the ship's lines plan (or offsets). Static and dynamic initial stability including the effects of mooring systems and other physical connections; Frequency domain dynamic analysis; The vertical/Z axis, or yaw axis, is an imaginary line running vertically through the ship and through its centre of mass.A yaw motion is a side-to side movement of the bow and stern of the ship. The transverse/Y axis, lateral axis, or pitch axis is an imaginary line running horizontally across the ship and through the centre of mass. A pitch motion is an up-or-down movement of the bow and Configuration of Hulls. While we have discussed the main types of hulls, let us now look at the basic configurations of hulls available. Monohull: Most vessels like barges or large carriers have a single hull of displacement, semi-displacement, or planning type. Multi-hulls: A vessel having two or more hulls is multi-hulled.When there are two hulls, it is known as a catamaran, while trimarans Reserve buoyancy is a key concept of ships stability lessons. Without which you simply cannot understand practical operation of ship and its seaworthiness. The term reserve buoyancy refers to the volume of enclosed space or the part of ship above the waterline that can be made watertight. In short it is the watertight volume of the ship above
Water sloshing in the swimming pool of a cruise ship undergoing pitching motion. In fluid dynamics, slosh refers to the movement of liquid inside another object (which is, typically, also undergoing motion).. Strictly speaking, the liquid must have a free surface to constitute a slosh dynamics problem, where the dynamics of the liquid can interact with the container to alter the system
'Ship stability' is the ability of a ship to return to a balanced location without capsizing when the ship is subjected to external forces or external moments (Francescutto, 2016). It is concerned with 'Static stability', 'Dynamic stability', 'Damaged stability' and 'Free surface' (Vassalos, 2000).
What is dynamic stability? It is defined as the energy required in heeling the ship from upright equilibrium till the angle of heel in question. It gives the stability information of a vessel considering dynamic behavior of the sea. It is expressed in terms of area under righting moment curve or GZ curve. Its unit is meter-radians.

Surface Stability of Submarines. A submarine in surfaced condition has to satisfy the same stability principles as that of a surfaced ship. The primary requirement in surfaced condition is that, it should remain afloat even after any kind of damage. Which means, there should be a significant volume of the hull above the waterline.
