Longitudinal bulkheads have a similar purpose, but damaged stability effects must be taken into account to eliminate excessive heeling. Today, most ships have means to equalize water in sections port and starboard (cross flooding), which helps limit structural stresses and changes to the ship's heel and/or trim.
When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre.
Ship stability – Ship response to disturbance from an upright condition; Ship motion test – Scale model a hydrodynamic test to predict full size behaviour; Six degrees of freedom – Types of movement possible for a rigid body in three-dimensional space; Flight dynamics – Study of the performance, stability, and control of flying vehicles
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).
Reconstruction of a 19th-century naval architect's office, Aberdeen Maritime Museum General Course of Study leading to Naval Architecture degree Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation ...
The sheer is a measure of longitudinal main deck curvature in naval architecture. The sheer forward is usually twice that aft. Increases in the rise of the sheer forward and aft build volume into the hull, and in turn increase its buoyancy forward and aft, thereby keeping the ends from diving into an oncoming wave and slowing the ship.
Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...
Large, modern ships are now often built in a series of pre-fabricated, complete hull sections rather than being built around a single keel, so the shipbuilding process commences with the cutting of the first sheet of steel. [7] The most common type of keel is the "flat plate keel", which is fitted in most ocean-going ships and other vessels.
