A characterization of the maximum bending stress of the SLICE hull in random seas

Abstract

A study of the effects of speed, heading and sea state on the maximum longitudinal bending stress of the SLICE Advanced Technology Demonstrator is presented. Strip Theory is applied to a model of the SLICE hull. The hull is modeled using data from a current design and with ship loading weight information for ferry operations. Stress results are based on conventional beam theory applied to the hull girder. Bending moment distributions are presented for random, fully-developed, uni-directional seas. The maximum expected bending stress is calculated for varying sea states, ship speeds, and wave directions. Operability of the SLICE based on limiting material stress is evaluated for sea states through sea state 6. The results of this study indicate that increased stiffening of the hull could be considered in the vicinity just aft of the forward pods.
