Lashing bridges Ship`s Equipment Centre Bremen GmbH May 2011 © Technical alterations reserved 8.3 Description When the requested stackload for 40’ containers is exceeding the limit of approx. 100 tons lashing from hatch cover level might no longer be sufficient. For this reason lashing bridges are installed between 40’ hatches in order to realise more effective support by the lashings. Higher container weights can be realised in the upper tiers while the lashing system can be simplified, i. e. double cross short lashing system (Para-Lash) to be used for 40’ containers from lashing bridge level. Heavy and unhandy long lashing bars should not be used except at some outermost stacklocations. The installation of lashing bridges does not have any effect on 20’ stackloads because 20’ containers still have to be lashed from hatch cover level at midhatch position. The possibility to stow non-standard containers others than 20’/40’ ISO containers is restricted. For example 45’ containers can be loaded on top of two tiers 40’ containers otherwise they would interfere with the lashing bridge structure. Alternatively the length of hatch covers can be increased and additional foundations for 45’ containers to be arranged. It has to be kept in mind when elongating the hatches lashing operation of 40’ containers will become more difficult due to increased gap between lashing bridge and 40’ container end.
