6、 a simplified method based on the assumed damage, as given in 3.0 or 4.0. The residual bending strength should be analyzed for both collision and grounding situations. The residual shearing strength should be checked for collision, but need not be analyzed for grounding. O Grounding Collision 1.1 1
