Analysis and Assessment of Residual Ultimate Strength for Damaged Bulk Carriers

Considering the asymmetry cross section of damaged hull girder and the different inclination conditions after grounding and collision, based on the Common Structural Rules for bulk carriers by IACS , this paper proposes the progressive collapse method to analyze the residual ultimate strength when the damaged ship is on several accidental situations. A program is developed in FORTRAN language and can be used to calculate the res idual ultimate strength for damaged ships. A bulk carrier is systematically assessed for its safety and some useful conclusions have been drawn.
