An attempt was made at the designing of a 50,000 DWT ore carrier to decrease the number of transverse bulkheads in wing tank part by means of increasing the length of tanks as long as possible, but such arrangement was found to be rather difficult because of the NK requirements that an ore carrier must remain afloat with two adjacent compartments flooded. Therefore, in order to reduce an inclining moment at flooding, alternate wing tanks on one side of the ship were connected with those on the other side through double bottom compartments as shown in Fig.1. The effect of this arrangement was thoroughly proved by a series of experiments using a ship model to a scale of 1/100. The following observations were also made at the experiments; (a) the effect of trim on heel angle,(b) the effect of GM on heel angle at various trim conditions, (c) the effect of width of the connected tanks on heel angle, (d) ore hold flooding.
