Abstract:

This report summarizes a major research and development effort and presents guidelines for design of advanced double hull ADH naval combatants, auxiliaries and commercial tank vessels. The program was undertaken to improve upon conventional, double hull tanker structure typically consisting of grillage of longitudinal and transverse framing. The ADH framing system is an alternative concept with only longitudinal, unidirectional framing. It embodies an inner hull and an outer hull, which are connected by longitudinal floors or web girders forming a cellular structure similar to a corrugated box. This allows elimination of conventional transverse frames and longitudinal stiffeners on the shell plating. The structural behavior of the ADH is significantly different from that of conventionally framed grillage structure requiring different design methods. The advantages anticipated for this concept are simplification of structure, improved structural resistance in case of collision or grounding, greater resistance to fatigue failure, improved survivability from weapons and reduced construction and maintenance costs.
