501. Floors

1. In single bottom structures, the lower parts of hopper holds are to be provided with solid floors at every frame space.

2. The inside of cellular keel is to be provided with transverse ring which have the same scantlings of solid floor at every frame space.

3. The scantlings of large space in double bottom such as proved direct calculation method.
