Abstract

For design evaluation there is a need for a method whichis fast, practical and yet accurate enough to determine theabsorbed energy and collision damage extent in shipcollision analysis. The most well-known simplifiedempirical approach to collision analysis was madeprobably by Minorsky and its limitation is also wellrecognized.The authors have previously developedsimple expressions for the relation between the absorbedenergy and the damaged material volume which take intoaccount the structural arrangements, the materialproperties and the damage modes. The purpose of thepresent paper is to re-examine this method’s validity andaccuracy for ship collision damage analysis in shipdesign assessments by comprehensive validations withthe experimental results from the public domain. Twentyexperimental tests have been selected, analysed andcompared with the results calculated using the proposedmethod. It can be concluded that the proposed methodhas a good accuracy with the mean value of 0.988 andstandard deviation of 0.042.
