Foreword

GB/T 23305 "topology shipbuilding hull structure elements" is divided into three parts.

Part --- 1. position of the unit;

Part --- 2. Describe the unit;

Part --- 3. Relationship between units.

This section GB/T 23305 Part 1.

This part identical with ISO 9203-1. 1989 "topology shipbuilding hull structure elements - Part 1. position of the unit" (in English).

This section is equivalent translation ISO 9203-1. 1989.

For ease of use, this section made the following editorial changes.

--- "This International Standard" be replaced by "this section";

--- With a comma "," instead of a comma as described, "";

--- Delete international standards foreword.

This part is proposed by the China State Shipbuilding Corporation.

This part of the National Marine vessel Standardization Technical Committee shipbuilding base Technical Committee (SAC/TC12/SC3) centralized.

3 Position, hull structure elements

3.1 Structural units

Hull structure elements are divided into the following four groups.

a) an outer panel (see 3.3);

b) Other panel units, such as. bulkhead panels, decks, floors, double bottom (see 3.4);

c) The main structural beams, such as. Strong ribs, strong girders (see 3.5);

d) stiffeners (see 3.5).

3.2 Boundary line file

For plate elements in numerical representation, the main structural beams and cables stiffeners and plate margin line and other boundary files should be standard boat Storage size line format standard hull form format see GB/T 23304.

3.3 Outer panel

Outer plate as a unit throughout the hull, with an identifier represented.

3.4 Other panel unit

It should be based on the following information to determine the position of the inner plate element.

a) unit identifier (up to 12 characters);

b) plane delimiter (plane equation coefficients A, B, C, D are the real amount) or non-planar indicator;

c) symmetric code (T = about centerline of symmetry and on both sides, S = starboard, P = port side, C = at or passing through the center line);

The number d) boundary line, like;

e) of the rope boundary lines for each boundary line.

--- Border unit identifier and connection identifier (cell or border unit if defined non-planar), or

--- Plate margin line identifier;

On f) cell thickness point code (U =, D = lower, F = front, A = after, S = starboard, P = port side, H = symmetrical division of thickness).
