The 2008 version of the Code details guidelines on Second Generation Intact Stability for ships, specifically criteria for dynamic stability and damage assessment. [7] The Code is split into two parts. Part A contains mandatory criteria. Part B contains additional guidelines and recommendations. [4]
Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity , centers of buoyancy , the metacenters of vessels, and on how these interact.
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).
Criteria for this dynamic stability effect remain to be developed. In contrast, a "tender" ship lags behind the motion of the waves and tends to roll at lesser amplitudes. A passenger ship will typically have a long rolling period for comfort, perhaps 12 seconds while a tanker or freighter might have a rolling period of 6 to 8 seconds.
Chapter II-1 – Construction – Subdivision and stability, machinery and electrical installations The subdivision of passenger ships into watertight compartments so that after damage to its hull, a vessel will remain afloat and stable. [2] This includes compliance with the International Code on Intact Stability
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.
Removal will allow them to access a key portion of the roadway, now perched above the containers on board the 980-foot, Singapore-flagged ship when it lost power and struck the bridge March 26.
