Accuracy analysis of stowing computations for securing non-standard cargoes on ships according to IMO CSS Code

The article takes up a subject of effectiveness of securing arrangements while stowing non-standard cargoes on ships. Accuracy analysis of stowing calculations was based on procedures proposed by Code of Safe Practice for Cargo Stowage and Securing – CSS Code. Detailed calculations of forces and moments related to lashings, which prevents non-standard cargo against transverse tipping, were performed. Some simplifications were proven that may result in underestimating or overstating the calculated righting moment, which decides of safety margin of securing non-standard cargoes. The alternative more reliable procedure, without simplifications, was proposed.
