DNV DNV CLASSIFICATION NOTES 31.7 [ Revised ]

Introduction

General

The "Rules for Classification of Ships" may require direct structural strength analyses in case of a complex structural arrangement, or unusual vessel size.

This Class1hcatton Note describes the scope and methods required for structural analysis of container vessels and also the background for how such analyses should be carried out. The description has been based on relevant DNV Rules, guidance and software.

Structural imalysis carried out in accordance with the procedure outlined in this Classification Note will nonnally be accepted as basis for plan approval.

Where in the text it is referred to the Rules, the references refer to the latest edition of "DNV Rules for Classification of Ships".

Any recognised calculation method or computer program may be utilised provided the effects of bending, shear, axial and torsion deflections are considered when relevant

If the wave loads are calculated from a hydrodynamic analysis, it is required to use recognised software. As recognised so ftware is considered all wave load programs that can show results to the satisfaction of the Society.
