To find an accurate MOI value of an object, one needs to know the object s actual shape and density to be able to calculate the MOI through integration.  Determining the exact MOI for a complete vessel, comprised of thousands of items, is not practical.  Instead, engineers simplify the parts of the vessel to point objects or  to standard shapes like a box or a cylinder, and calculate an approximation of the MOI.  The accuracy of this  approximation is dependent on the number of parts the vessel is divided into and how well the shape, orientation and  density of each of the simplified items resembles the real objects.  The quantification of the inaccuracy involved is  seldom addressed.  This paper describes a method to find the absolute error range for this simplified MOI calculation  by finding the extreme values the MOI approximation can generate, and quantifies the effect that an error in MOI can  have on the results of various types of performance analysis.</style></abstract><call-num><style face="normal" font="default" size="100%">3497</style></call-num><custom1><style face="normal" font="default" size="100%">Non-Member Price: $16.38.
