1.1.1 The requirements
of this Chapter apply to both self-propelled ships with machinery
aft and to non-propelled ships (barges and pontoons).
1.1.2 For the determination of the longitudinal strength, design bending moments
are to be calculated for all ships with a length, L, exceeding 65 m. The methods
for calculation of design bending moments are given in Pt 3, Ch 4, 5 Design bending moments. The determination of longitudinal strength of ships with a
length, L, of 65 m and less is generally not required.
1.1.3 The longitudinal
strength of self-propelled ships where the machinery space is not
situated aft and the length, L, exceeds 40 m will be
specially considered; the design bending moments are to be determined
by direct calculation.
