CARGO SECURING ON RO-RO VESSELS, CALCULATION OF FORCES ON CARGO AND IN LASHINGS

This paper describes what factors are taken into account when calculating forces to design a lashing system for Ro-Ro cargoes. Detailed consideration is given to ship motions and how they affect the behaviour of various types of cargo and subsequent design of lashing systems. The securing of trailers which have integral suspension systems is discussed at some length and treated as a special case. As far as choice of lashing goes, the most popular type is chain lashing, as these are light for their strength, flexible and easily stowed. Methods of tightening are the lever system and the bottlescrew or ratchet method and the advantages of each is described. In conclusion, the Author states that from a manufacturer's point of view any advice given must be related to the various design and operational factors of lashing systems so that the vessel is as safe in heavy weather as it could possibly be.
