A Complete Guide to Understand Damage Stability Better

Thanks for the great article. Can you please advise if damage stability criteria should be met at all times including while entering and leaving port or only at sea during ocean passage. Basically can vessel sail out and take ballast in DB tanks to increase GM to meet the damage stability criteria?

Sir the flooding graph is drawn on a graph using the lenght of floodable compartment then how do we determine whether the ship will withstand the flooding of the compatment by super imposing the graph on the vessels length using the same compartment length ? each time the length of the compartment should touch the graph since same length is used to draw the graph

Wonderful explanation Sir. My concept is clear. Thanks

Dear sir Tnx for your valuable articles. Can you please furnish us with "how to use of tables of a specific ship, what to check, why some cases are some not" where loading condition are used against damage cases at initial and equilibrium condition

Very nice explanation! clear and easy to understand. It will be very useful for the CoC exam i will do next week :). Anyway, I have a question regarding Subdivision loading: as per SOLAS cp. II - 1a, passenger ships and roro can have subdivision loading depending on the different condition of the load (C1, C2, C3,etc...). This loading is calculated from the compartment factor, floodable length and service factor of the ship. Anyway, I really can't understand what this line means: first of all is the subdivision load line corresponding to the margin line (76 mm below bulkhead deck)? second of all, as per SOLAS, the subdivision load line shall NOT, in any case, be ABOVE the deepest saltwater load line calculated for that season as per LLC. How can it be that a subdivision load line is, theoretically, under a North Atlantic load line? wouldn't it means that in case of submerging any deeper than the subdivision line, the ship will sink? with this point of you should be impossible to load the ship any deeper than the C1, not even mentioning that Tropical water and freshwater load line would be never reached. I hope to have been clear enough with my question. Thank You

what is factor of subdivision? how its calculated?

What i have to understand is : in the Curve of Floodable Lenght and Probabilistic Assessment the damage stability criterias are dealt on the stage of construction so it depend only how we construct the ship. Why in the deterministic method the Officer shall check this requiriments if they depends from the construction of the ships same like the first 2 methods? thank you

Dear Sir, pls note all vessels have cross flooding arrangements not only passenger ships. WBT's considered as cross flooding arrangements as ballast could be transferred internally in case of flooding.

Explained very nicely and in detail. Thank u very much Sir for sharing such needful knowledge.
