Passenger ships – Longitudinal extent of damage; |
3m + 3% of L or, 11m whichever is least. Where the required factor of subdivision is 0.33 or less the longitudinal extent must be increased to include flooding of any three consecutive compartments. |
| Passenger ships – Transverse extent of damage; | 20% of B measured inboard from the ship’s side at right angles to the centreline at the level of the deepest subdivision load waterline taken parallel to the keel |
| Passenger ships – Vertical extent of damage; | From the baseline upwards without limit |
| Any other damage; | If any damage of a lesser extent would may cause a more severe condition regarding heel or loss of metacentric height, such damage shall be assumed for the purpose of the calculation |
| Passenger ships – When does the damage stability apply?; | In the final stage after damage and after equalisation |
| Passenger ships damage stability – Residual area under curve; | At least 0.015mr measured from the angle of equilibrium to the lesser of; – Angle of flooding – 22 deg from upright (one flooded compartment) or 27 deg from upright (two or more flooded compartments) |
| Passenger ships damage stability – Range of positive stability; | At least 15 deg beyond angle of equilibrium |
| Passenger ships damage stability -Maximum GZ; | Residual righting lever (GZ) value to occur within the range of positive stability when determined by the formula; GZ(m) = heeling moment / displacement (+ 0.04) When the heeling moment is taken as the greater value of any one of the following effects; – Crowding of passengers to one side of the ship – Launching of all fully loaded, davit launched survival craft on one side of the ship – Pressure of wind on the side of the ship In no case shall the GZ value so determined be less than 0.1m |
| Passenger ships damage stability – Assumed flooding; | Sufficient intact stability in all conditions to withstand flooding of any 1 main compartment or; -Where factor of subdivision is 0.33 – 0.5 to withstand the flooding of any 2 adjacent compartments or; – Where factor of subdivision os 0.33 or less to withst About UsMarinegyaan.com is not just another website; it’s a mission to create World’s Biggest Online Marine Encyclopedia for the World and to find solutions that are of extreme importance to all seafarers across the globe. Marine Gyaan Encyclopedia is a free online resource aims to document all maritime subjects and queries to replace bulky reference books. It is a benevolent reference work for Maritime community in an exhaustive manner. Our encyclopedia covers a great collection of study materials and detailed notes in subjects such as Navigation, Cargo work, Ship operation technology, Meteorology, ROR and Ship Stability etc. Searchable index include more than 2000 nautical topics in expected MMD written and oral exams with pinpoint answer, making our site a good all around tool for MMD exams preparation. The collaborative and constantly updated encyclopedia is free for everyone to use and perfect for candidate who are preparing for MMD written or oral exams such as Second mate, Chief mate or Masters. All of the entries have been written and approved by actual scholars, which means you won’t have a problem when it comes time to cite sources. In addition to our massive store of reference material for fellow mariners, we are providing online bookings for various Maritime courses in maritime institutes across India.
