Section 2 Frame Spacing

201. Transverse frame spacing

1. The standard spacing of transverse frames is obtained from the following formula:

Ċ Ņ Ī Ã Ñ ĨJL (mm)

2. Transverse frame spacing in fore and after peaks is not to exceed 610 mm or the standard spacing specified In Par 1, whichever is the smaller.

3. The requirements in Par 2 may be modified, where structural arrangement or scantlings are suitably considered.

202. Longitudinal frame spacing

The standard spacing of longitudinal frames is obtained from the following formula:

Ċ Ņ Ī Ã Ñ JJL (mm)

203. Consideration for frame spacing exceeding the standard

Where the spacing of frames is equal to or above the spacing of 250 mm greater than the standard spacing in 201. and 202., the scantlings and structural arrangement of single and double bottoms and of other relevant structures are to be specially considered.
