Each member body interested in a subject for which a technical committee has been established has the right to be rep

18、olerances Part 1: General principles3 General principlesGeneral principles of dimensioning are as follows.a) The basic types of lines, their designations, as well as general rules for draughting of lines, are specified in ISO 128-25.b) The rule of indication of dimension and tolerances are specified
19、 in ISO 129-1.c) The location dimension of the hull structure shall be indicated with the distance of the assembled moulded line of the member from reference line (BL = base line, CL = centre line, AP = after perpendicular, FP = forward perpendicular, WL = water line).d) The dimensions of the same m
20、ember(s) shall be indicated only once; the dimensions of the members with identical specifications and sizes shall be indicated only once; these dimensions should be on the view(s) of the drawing that displays the member(s) most clearly.4 Basic requirements4.1 GeneralDimensions indicating the locati
21、on of a structural member in the hull shall be referenced as follows. In longitudinal direction: to a structural frame or to a station or to midship In vertical direction: to a BL, to a WL, or to a deck line In transverse direction: to a CL or to a broadside1) To be published.

They may be oblique and parallel as shown in Figure 3 (b).4.3.3 Dimension lines which start at one end at a reference line may be terminated at one end only if the dimension line otherwi

For examples, see Figure 4 (a) to Figure 4 (c).(a) (b) (c)Figure 44.3.4 At a rounded corner of the shear strake, an idealized corner point shall be drawn by extension lines of the moulded plate edges, as shown in Figure 5. The dimensions are referenced to this corner point.

If the drawing would become too crowded, dimensions may be written above leader lines pointing towards the dimension lines.4.4.2 Gene

Measures are separated by “x”.b) The coaming height, h, i.e. the distance of the lower edge of a door opening from the upper side of the deck below, may be defined by “h” preceding the measure, e.g. h200 in the open
32、ing far right.c) The four corner radii of an opening shall typically be presented once by “R” preceding the measure.d) Dimensions locating openings shall refer to their centres. The vertical distance, thereby, is normally referenced to the deck below.e) There is no need to dimension the distance fro
33、m the centre of openings to the moulded lines of neighbouring stiffeners if it is intended to locate the opening in the middle between the stiffeners.f) Equally sized and arranged openings shall be dimensioned only once.Figure 84.4.7 Dimensioning of manholes and lightening holes shall be as shown in
34、 Figure 9 (a) and (b); abbreviated “MH” shall be stated as shown in Figure 9 (a).
