PROBABILISTIC DAMAGE STABILITY: Knowledge and Understanding
PROBABILISTIC DAMAGE STABILITY: Knowledge and Understanding
The goal of this manuscript is to provide more knowledge for ship designers with respect to probabilistic damage stability PDS . More precisely, the manuscript aims to give more insight to how certain changes in the arrangement and intact stability affect the PDS or A-index for a specific vessel. The following two objectives can be investigated: First, what is the effect on the A-index of changing the size of the particular tanks located along the ship, by changing the height of the horizontal deck?; secondly, what is the effect on the A-index of changing the intact stability of the ship, i.e. the ship’s initial GM values for the three subdivision draughts dS, dP and dL? The background for the abovementioned goal, is the introduction of the PDS regulations by IMO in 2009. Ship designers are forced to use the probabilistic approach instead of the deterministic approach DDS , for certain vessel types when calculating damage stability. PDS offers more freedom than DDS in the design of the ship’s internal watertight arrangement. However, since PDS calculations usually are conducted at late design stages, it may be challenging to utilise this flexibility due to time pressure. Thus, ship designers often rely on experience, since there is little time for research and optimisation. The author would therefore like to contribute with more knowledge and understanding to damage stability
