Not only allowable stress criterion but also ultimate strength criterion should be satisfied for ships in compliance with Common Structure Rules(CSR) coming into force on April 1,2006.

Then, residual strength index of damaged ship hulls is given based on extreme loads and ultimate strength calculations.
