Use the floodable length curve in Section 1, the blue pages, of the Stability Data Reference Book. If the curve represents 45 percent permeability and number 2 hold floods, the vessel will sink if the permeability exceeds what percent?
⢠Floodable length curve usage in the blue pages of the Stability Data Reference Book ⢠Relationship between permeability (%) and whether a compartmentâs flooding will cause the vessel to sink or survive ⢠How to read the critical permeability value from the curve for a specific hold (No. 2)
⢠On the floodable length curve for No. 2 hold, how do you locate the point that corresponds to 45% permeability, and what does that point represent? ⢠If the vessel is safe at 45% permeability, do you look for the permeability value at which the curve just reaches the shipâs actual compartment length or position? ⢠How does increasing permeability change whether the compartment flooding stays within the floodable length or exceeds it?
⢠Be sure you are using the correct hold (No. 2) on the floodable length diagram in Section 1 (blue pages). ⢠Confirm where the actual length/position of No. 2 hold intersects the floodable length curve as permeability changes. ⢠Identify the smallest permeability value above 45% at which the floodable length becomes less than the compartment length â that is the critical âsinksâ permeability.
