Calculation Examples of the Added Mass of a Tanker Coming alongside the Quay

Abstract

Recently tankers become very large, therefore we need to estimate the added mass when they come alongside the quay. This paper presents the calculation examples for this purpose. Two-dimensional potential flow is assumed and the numerical calculation is done by the finite element method. According to the results, the effect of the water depth on the added mass is considerably large, but the distance between the ship and the quay has small influence on it. In order to examine the accuracy of this method, a result is compared with the one calculated by the hypercircle method. They agreed very well.
