DECK STIFFENING Decks may be framed transversely or longitudinally
but outside the line of openings it is preferred that longitudinal framing
should be adopted for the strength deck.
When the decks are longitudinally framed the scantlings of the longitudinals
are dependent on their spacing, the length of ship, whether they are
inside or outside the line of hatch openings, their span and the deck loading.
Deck transverses support the longitudinals, and these are built from a
deep web plate with flange or welded face flat, and are bracketed to the side
frame (Figure 19.1). Within the forward 7.5 per cent of the ship’s length,
the forecastle and weather deck transverses are closely spaced and the
longitudinal scantlings increased, the additional transverse and longitudinal
