[接上页] Cap 369C reg 6 Definition of subdivision terms (1) The Subdivision Load-line (分舱载重线) is the water-line drawn parallel to the keel, used in determining the subdivision of the ship. (See also paragraph 16). (2) The Length of the Ship (L) (船舶长度(L)), in ships of the usual form at the ends, is to be measured between perpendiculars taken at the extremities of the deepest subdivision load-line.* (See note (i), Appendix I). (3) The Breadth of the Ship (B) (船舶宽度(B)), is the extreme width from outside of frame to outside of frame at or below the subdivision load-line. (4) The Bulkhead Deck (舱壁甲板) is the uppermost continuous deck to which all transverse watertight bulkheads are carried. (See also paragraph 7). (5) The Margin Line (限界线) is a line drawn parallel to the bulkhead deck at side line, and three inches below the upper surface of that deck at side.+ (See also paragraph 7 and Notes, Appendix I). (6) The Draught (d) (吃水(d)) is the vertical distance from the top of keel amidships to the subdivision load-line. (7) The Freeboard (f) (干舷(f)) is the vertical distance from the subdivision load-line to the margin line amidships. (See also Notes, Appendix I). (8) The Sheer (舷弧) of the bulkhead deck at any point is the vertical distance between the beam at side line at that point and a line drawn parallel to the subdivision load-line at the height of the beam at side line amidships. (See also Notes and Diagrams 1 to 6, Appendix I). (9) The Block Co-efficient of Fineness of Displacement to Subdivision Load-Line (至分舱载重线的排水量方形系数) referred to in Appendix I shall be determined as follows-Volume of displacement to moulded lines divided by (L. B. d.). (10) The Permeability (m) (渗透率(m)) of a space is the percentage of that space which can be occupied by water. The volume of a compartment which extends above the margin line shall be measured only to the height of that line. (See paragraphs 9 and 11). (11) The Machinery Space (机舱) is to be taken as extending in length between the extreme main transverse watertight bulkheads bounding the spaces devoted to the main and auxiliary propelling machinery, including boilers when installed, and it shall contain all permanent coal bunkers. (See also paragraph 11). (12) Passenger Spaces (客舱) are those which are provided for the accommodation and use of passengers, excluding baggage, store, provision and mail rooms. For the purposes of paragraphs 9 and 11, spaces provided below the margin line for the accommodation and use of the crew shall be regarded as passenger spaces. (13) A Watertight Deck (水密甲板) is a deck so constructed as to prevent water under pressure from passing through in either an upward or a downward direction. (14) A Weathertight Deck (风雨密甲板) is one through which, in ordinary sea conditions, water will not penetrate in a downward direction. The bulkhead deck is in all cases to be weathertight in this sense unless there is a deck above it which is weathertight. (15) Units of Measurement. Except where otherwise specified all linear dimensions are to be in feet and volumes in cubic feet, the latter being calculated to moulded lines. (16) For floodable length (可浸长度), permissible length (许可长度), factor of subdivision (分舱因数) and criterion of service (业务衡准) see paragraphs 7, 10, and 11 respectively. ___________________________________________________________________ Note: * No adjustment to this length will, as a general rule, be necessary unless the sectional area at the after perpendicular exceeds one-tenth of the midship sectional area, in which case full particulars should be submitted in order that an equitable length may be determined. + Where there is a variation in the thickness of the bulkhead deck at side, the top of the deck should be taken at the least thickness of the deck at side above the beam. If desired, however, the top of the deck may be taken at the mean thickness of the deck at side above the beam as calculated for the whole length of the deck; in this calculation no greater thickness is to be used than the least thickness plus two inches. Cap 369C reg 7 Floodable length Flooding calculations (1) In order to determine the subdivision of a ship it will be necessary to develop flooding curves which will indicate the floodable length at any point in the length of the ship. (2) For a ship which has a continuous bulkhead deck this floodable length is the maximum portion of the length of the ship having its centre at the point in question, which can be flooded under the definite assumptions as to permeability laid down in paragraph 9, without submerging the margin line. (3) If the ship has not a continuous bulkhead deck, the floodable length is to be calculated with reference to an assumed continuous margin line up to which, having regard to sinkage and trim after flooding, the sides of the ship and the bulkheads are watertight, special consideration being given to the requirements of these Instructions in which reference is made to the margin line. Examples of the procedure to be followed in certain cases are given in Diagrams 2 to 6, Appendix I. |
