Introduction

For ships intended for container transport the “Rules for Classification of Ships” require that approved securing arrangements for the cargo containers are fitted.

The purpose of this publication is to serve as an aid to those responsible for the planning and strength evaluation of securing arrangements for cargo containers on board ships. Acceptable assumptions and calculation procedures supplementing the general requirements stated in the Rules for Classification of Ships are given.

Principles of analysis have been outlined for normal types of securing arrangements, including cellular containment structures (rigid containment system).

For securing arrangements based on lashings or similar, calculation formulae taking into account the interaction of containers and supports have also been included.
