Luis, R.M., Hussein, A.W. and Guedes Soares, C. (2007), “On the Effect of Damage on the Longitudinal Strength of Ships”, Proceeding of the 10th International Symposium on Practical Design of Ships and Other Floating Structures (PRADS´07), 2007, Houston, Texas, United States of America, American Bureau of Shipping
The objective of this work is to study the longitudinal strength of the ship remaining after grounding or collision. Two Suezmax tankers are used in this study, one having one longitudinal bulkhead and the other no longitudinal bulkheads. The width and penetration of the damage were considered which allows presenting the relationships between its dimensions and the residual strength. The calculations were performed using a computer code based on the Smith method. The damage is simulated by removing the damaged elements from the midship section. Coefficients are proposed for the interaction equation for the collapse of the ships with damage in combined loading. It was found that the residual strength is dependent on the position, value and geometry of the damage. The interaction coefficients, for unsymmetrical damage, are different for port and starboard, otherwise is not possible correctly characterize the relationship between the vertical and horizontal moments.
