Experimental Study on the Strength of Collision Barrier of Ship

Abstract

To know what strength the ship side structure has against a collision of ships is very important in estimating the severity of a collision accident. In the nuclear powered ship, especially, it is imperative to provide a collision resisting structure on the sides of the atomic pile chamber. Following points of the investigation have been tried to clarify through the experimental tests by using models in 1/15 scale for the necessary informations to the both, designing and evaluating allowable safety limit, at collision barrier for the critical collision in nuclear powered ship. (1). Effect of difference of relative strength between the bow and the side structures on the shock resisting energy capacity through the tests on various kinds of bow structure models and side ones (2). Effect of relative dimensions of deck plate and side shell plate, and layers of decks of collision barrier on the shock resisting energy capacity through the collision tests, pressing the rigid bow model onto the side structure models. A new semi-empirical formula for calculating total energy absorbed by shock resisting construction has been obtained from the test results.
