The Oil Pollution Act of 1990, as well as the U.S. Navy's desire for increased survivability, has focused ship structural designers' attention on alternative double hull structures. Unidirectionally Stiffened Double Hulls (USDFH) have surfaced as the most promising structural designs due to their producibility. This paper examines the ability of USDH to withstand grounding damage. The extent of hull penetration has been calculated and related to the ship's gross characteristics, hull structure geometry, and the geometry of the obstruction. The extent of hull penetration and lifting for varying reef heights and spreading angles for a USDH tanker is given as an example.
