Positloning for ship's side scuttles. This standard is equivalent to IS05780—1987 Shipbuilding 1 Content and Scope of Application
This standard specifies the positioning rules for ship's side scuttles. 2 Terminology
2.1 Sill
The lower part of the window opening.
2.2 Positioning
Determination of the installation position of the window on board.
3 Positioning rules
3.1 General
- Positioning.
.GB/T14356-93
The positioning of the window shall comply with the relevant provisions of international conventions, rules, ship classification rules and the competent authorities of the country of ship registration. 3.2 Basis for positioning
3.2.1 The positioning of the window is related to the length of the ship L and the height Y of the window above the summer load line S (see Figures B1 to B4 in Appendix B). If the timber load line is given, the height is calculated from the distance from the seasonal timber load line to the sill. 3.2.2 The positioning of the window is related to the type of the window (A, B, C) and its installation position on board (i.e. the front wall, side wall and rear wall of the superstructure and deckhouse below the dry deck). 3.3 Positioning restrictions
3.3-1 No sash shall be installed at the position where the sill of the window is below the parallel line of the boat deck at the ship's balance. The lowest point of the parallel line is 2.5% of the ship's breadth or 500 mm above the summer trim line (or summer timber load line), whichever is greater. 3.3.2 For ships that need to meet damage stability requirements, non-openable windows shall be installed on the outer side of the sill of the window below the final waterline in the damage state and the space where water will splash after damage.
3.3.3 The area between the position specified in 3.3.1 and 3.3.2 and the part below the curve in Figure B1 of Appendix B shall not be installed. 3.4 Scenery covers
3.4.1 Only heavy or medium-sized touch screens with permanent storm covers are allowed to be installed on the side shell of the ship or the first superstructure or deckhouse with access to the space below the dry deck. 3.4.2 Heavy or medium plastic windows with permanent storm protection shall be installed in cabins of second-tier superstructures with direct access to enclosed first-tier superstructures or spaces below deck 10. 4 Strength Limits
In addition to the application restrictions on teeth in 3.3, the lowest permissible position of windows also depends on their strength, which is related to the forces acting on the ship.
4.1 The maximum external force (design pressure) expected for construction
GB/T14356--93
is calculated according to the calculation method in Appendix A (Supplement). 4.2 Windows shall not be installed when the design pressure of any part of the ship exceeds the maximum permissible pressure that can be withstood by each penetration listed in Table 1.

Appendix A
Calculation of design pressure
(Supplement)
When determining the installation position of navigation windows for ships, the design pressure obtained by formula (A1) of this appendix shall be followed. When the protective opening defined in Article 18 of Annex 1 to the 1966 International Convention on Load Lines is used as the positioning basis for the entire window, this formula is used to calculate the allowable load of the exposed superstructure or deckhouse. A1 Calculation of design pressure
The design pressure P can be obtained by formula (A1).

The distance between the bulkhead where the window is located and the vertical line AP, in m. (If it is a side connection of a superstructure or deckhouse, this side shall be divided into several parts of approximately equal length, the length of each part shall not exceed 0.15L, and X shall be the distance between the vertical line AP and the center of each part).
A1.2 Calculation of hull length distribution coefficient
The length distribution coefficient b is calculated according to Table A2. WX/

Appendix
Window positioning diagram
(supplement)
This annex is based on Based on the calculation method of design pressure, the positioning of the window is determined in the form of the building. (A3) The installation of the window on the ship can be determined by Figure 31 and Figure 4. The minimum height from the summer load to the window sill can be obtained from the figure. The curve in the figure is the minimum pressure that this type of window can withstand (240kPa for military type, 120kPa for medium type, and 60kPa for light type). kPa).

In Figure B1 to Figure B, the solid line of Y-0.5 m water is the lowest oxygen limit line of the window. The curve below this line is represented by a dotted line, and the part represented by the line is not allowed to slow down!. The curves drawn with dotted lines in Figures 31, B2 and B3 represent the degree to which the lowest sill of the window installed on the end wall is higher than the lowest sill of the window installed on the side wall at the same direction. The vertical integral value of this curve is called the additional height. B1.1 Heavy window compensation curve is based on 731.

B2.1 Apply a scaled drawing (such as a general layout plan, a longitudinal plan or a side tank capacity plan with a summer load line) B2.2 Draw a coordinate line from ! to ' on the drawing. cm
B2.3 Obtain the coordinate value Y of the type of window used from Figure B1 (or Figure 2, Figure B3), and use this value to mark the corresponding coordinate point on the corresponding longitudinal position line, starting from the summer load line (or summer vertical load line). B2.4 Connect the above coordinate points into a smooth curve, which is the lowest position line of the type of window installed on the ship's outer plate, superstructure or mid-plate room side wall. See Figure B5. (This position line shall be subject to the restrictions of Articles 3.3.1 and 3.3.2). H2.5 From the four-dot-dash line in Figures B1, B2 and B3, obtain the minimum sill additional height of the navigation window installed on the front wall. Add this height to the corresponding height on the curve specified in Article B2.4, which is the minimum sill position W when this type of navigation window is installed on the front wall of the superstructure or deck.

According to the definition of the International Convention on Load Lines in 166, PA (Positinn Approximately 1.00 is the end position group line symbol for the projectile energy length: when the length is 1.00, the end position line is the tail line APB2.7.2 When drawing Figure B5: attention should be paid to the restrictions specified in 3.2 and 4.2. B2.7.3 The curve in Figure B-1 for all ship lengths is based on the square coefficient (C-.0.6) of Zhan Tianli, and the actual 1 . The value changes between 0.60.8. When the C value is 0608, the difference between the Y of the number surface reaches 3m, and the 1 cut surface reaches 12.7.4 The glare window on the front end of the installation case should take into account the distance between the window and the height above the flower deck. The design of the height of the small opening B2.7.5 The difference between the height of the high point line and the height of the section of 1 and 1 is about 0.5~1.
