Verdrag nopens een eenvormig stelsel voor de meting van zeeschepen
In determining the main floors of the ship or the top of double bottom, as referred to in Article 25, the indications given below shall be followed:
(a) With regard to the part of the ship situated between the collision bulkhead and the after peak bulkhead: (1) The bottom construction with solid transverse floors on every frame is to be considered as a standard construction and, whenever such floors are fitted, they shall be regarded as the main floors (see Figure 11).
(2) If the bottom construction consists of solid floors two or more frame spaces apart and skeleton floors of the same depth on the intermediate frames, such floors constitute the main floors (see Figures 12 and 13).
(3) If the bottom construction consists of solid floors on alternate frames and intermediate lower floors or frames, the tonnage depth should be measured to the higher floors (see Figure 14).
(4) If the bottom construction consists of floors of different depths, it must be determined whether the higher or the lower floors should be considered as the main floors. As a general indication, it should be noted that the lower floors are to be considered as the main floors when the higher floors are more than two frame spaces apart (see Figure 15).
(5) In the case of a bottom construction with longitudinal framing of a uniform depth, the upper edge of the longitudinals should be considered as the top of the main floors (see Figure 16).
(6) Should the longitudinal system consist of elements of different depths, the same provisions as given in paragraphs (3) and (4) will apply (see Figures 17 and 18).
(7) Mixed constructions of transverse and longitudinal framing are to be compared with the various systems referred to in the preceding paragraphs for the purpose of determining the main floors.
(8) If a double bottom is fitted, whether on the transverse or longitudinal system, and is adapted for the carriage of water ballast only, the tonnage depth should be measured to the top of the double bottom, but if available for the carriage of cargo, stores or fuel, the tonnage depth should be measured to the top of the main floors, determined in accordance with paragraphs (1) to (7), as for singlebottom ships (see Figures 19, 20, 21 and 22). Where the top of the main floors extends to the tank-top plating, the top of this plating may be regarded as the top of the main floors.
(9) The thickness of a ceiling, referred to in Article 25, is still to be deducted, even if such ceiling is laid on a double bottom or on floors, to which the tonnage depth, according to the above indications, is not to be measured.
(1) The bottom construction with solid transverse floors on every frame is to be considered as a standard construction and, whenever such floors are fitted, they shall be regarded as the main floors (see Figure 11).
(2) If the bottom construction consists of solid floors two or more frame spaces apart and skeleton floors of the same depth on the intermediate frames, such floors constitute the main floors (see Figures 12 and 13).
(3) If the bottom construction consists of solid floors on alternate frames and intermediate lower floors or frames, the tonnage depth should be measured to the higher floors (see Figure 14).
(4) If the bottom construction consists of floors of different depths, it must be determined whether the higher or the lower floors should be considered as the main floors. As a general indication, it should be noted that the lower floors are to be considered as the main floors when the higher floors are more than two frame spaces apart (see Figure 15).
(5) In the case of a bottom construction with longitudinal framing of a uniform depth, the upper edge of the longitudinals should be considered as the top of the main floors (see Figure 16).
(6) Should the longitudinal system consist of elements of different depths, the same provisions as given in paragraphs (3) and (4) will apply (see Figures 17 and 18).
(7) Mixed constructions of transverse and longitudinal framing are to be compared with the various systems referred to in the preceding paragraphs for the purpose of determining the main floors.
(8) If a double bottom is fitted, whether on the transverse or longitudinal system, and is adapted for the carriage of water ballast only, the tonnage depth should be measured to the top of the double bottom, but if available for the carriage of cargo, stores or fuel, the tonnage depth should be measured to the top of the main floors, determined in accordance with paragraphs (1) to (7), as for singlebottom ships (see Figures 19, 20, 21 and 22). Where the top of the main floors extends to the tank-top plating, the top of this plating may be regarded as the top of the main floors.
(9) The thickness of a ceiling, referred to in Article 25, is still to be deducted, even if such ceiling is laid on a double bottom or on floors, to which the tonnage depth, according to the above indications, is not to be measured.
(b) With regard to the parts of the ship situated forward of the collision bulkhead and aft of the after peak bulkhead: (1) If the floors are equal in height or lower than the floors or double bottom immediately contiguous to the collision bulkhead or after peak bulkhead, as the case may be, such floors constitute the main floors (see Figure 23).
(2) If the floors are higher than the floors or double bottom immediately contiguous to the collision bulkhead or the after peak bulkhead, as the case may be, the tonnage depth must be measured to an imaginary line drawn parallel to the keel at a level corresponding to the height of such floors or double bottom (see Figures 241) Peak tanks are not to be regarded as double-bottom tanks, even when the floors extend to the tank-top. and 25).
(1) If the floors are equal in height or lower than the floors or double bottom immediately contiguous to the collision bulkhead or after peak bulkhead, as the case may be, such floors constitute the main floors (see Figure 23).
(2) If the floors are higher than the floors or double bottom immediately contiguous to the collision bulkhead or the after peak bulkhead, as the case may be, the tonnage depth must be measured to an imaginary line drawn parallel to the keel at a level corresponding to the height of such floors or double bottom (see Figures 241) Peak tanks are not to be regarded as double-bottom tanks, even when the floors extend to the tank-top. and 25).
