Abstract
The tank ship is made of monolithic reinforced concrete and is formed with two symmetrical, longitudinal chambers for tanks, and an intermediate space for the operating mechanisms thereof. The massive reinforced concrete slabs which form the ship are reinforced partly by prestressed steel tendons and partly by mild (non-stressed) steel rods. The prestressed tendons running lengthwise of the ship are unspliced. The transverse bulkheads forming the ends of the tanks are curved in two directions, e.g. in the form of sections of hemispheres. Insulation is provided on the interior surface of the tank chambers and on both sides of the bulkheads.
