The mid-transverse section is considered one of the significant sections in the
shiphull, because it exists in the middle of its calculated length, where the bindings
moments reach the maximum, in consequence the hull strength can be determined thr
ough
the strength of this section. Its design process includes the determination of the dimensions
of plats and different framing beams and considered one of the important stages in the hull
design process. This research includes the estimation of calculated values of binding
moments, inertia and resistant’s moments of this section area, initiated from the providing
conditions of critical strength and fatigue strength. It also includes, the formals used for the
determination of longitudinal elements dimensions through the transverse thicknesses and
metal distribution type among them. The longitudinal strength of the hull was evaluated
according the perpendicular and tangential stresses.
