Collision and Grounding Design Standards
There are no universally accepted design standards for collision and grounding. Principles
are based on design objectives. Germanischer Lloyd has a class notation, COLL, that
ranks collision resistance. The American Bureau of Shipping has a class notation for
safehull vessels. It demonstrates the adequate residual hull girder following collision or
grounding accidents. The International Association of Classification Societies has
developed a series of unified requirements for bulk carriers under flooded conditions.
Though flooded conditions have not been defined, some requirements are against accidents
like collision and grounding.
