ABSTRACT:
A ship having at least its side portions and bottom portion comprised of a double hull construction consisting of an inner hull plating and an outer hull plating connected together solely, except for transverse bulkheads disposed in spaced apart relation in the lengthwise direction of the ship, by a plurality of connecting longitudinals fixed to the bulkheads, at least one of the connecting longitudinals having anti-buckling means extending in the lengthwise direction thereof and tripping means extending in the widthwise direction thereof. According to this arrangement, external forces exerted on the ship may be transmitted through the connecting longitudinals to the transverse bulkheads so that the inner and outer hull platings may be protected from buckling. The absence of transverses crossing the longitudinals considerably facilitates the automatization of welding operation. Furthermore, the fact that at least one of the connecting longitudinals has anti-buckling means extending in the lengthwise direction thereof and tripping means extending in the widthwise direction thereof assures that the longitudinals, or the inner and outer hull platings connected thereby will be more positively prevented from buckling.
