Exceptional cargoes, i.e. those which are particularly high or heavy, can, under unfavorable circumstances, shift sideways or lengthwise even when subjected to normal rolling and pitching of the vessel. This can cause considerable heeling, which can in turn lead to a loss of stability and ultimately to a total loss.
In order to effectively secure “non- or semi-standardized “cargoes against the forces that act on them at sea, tailored securing measures are required and a large number of varying factors have to be taken into account.
The robust und internationally recognized form of assistance is the Annex 13 of the "Code of Safe Practice for Cargo Stowage and Securing" (CSS Code) by the International Maritime Organisation. The Annex 13 was published in 1995 in response to a constant rise in the number of spectacular incidents at sea caused by inadequate cargo securing.
As the size and weight of “non-standardized “cargoes constantly increased in in the past 20 years, the German marine insurers see a vital need to bring Annex 13 into line with these developments. For that reason, they developed eight tangible suggestions which range from the revision of weather-based load assumptions to separate considerations of impact forces in tipping balances.
