Introduction

The "Rules for Classification of Ships" require a direct structural analysis to be carried out in order to cope with the comp lex ity in the loading of bulk carriers and the many possible loading conditions.

The structural analysis is generally rclalcd to primary strength members of the midship region of bulk carriers arranged with double bottom and single or double side and without separate longitudinal bulkheads. However, additional calculations may have to be carried out for foremost and aftmos1 holds as the hopper/top wing tank construction normally is changed significantly compared to the midship construction.

Any recognised calculation method or computer program may be applied provided the effects of bending, shear axial and torsional deformations are considered when relevant.

SLrength analysis carried out in accordam:.c with the procedure outlined in the Classification Note will nom1ally be accepted as basis for class approval.

Nauticus Hull is a comput.er program offered by DNV that is suitable for the calculations specified in this Classification Note.
