ABSTRACT: This
paper reviews the state-of-the-art research on collision and
grounding. It focuses on the three issues that a standard for
design against accidents needs to address: definition of accident
scenarios, evaluation approaches, and acceptance criteria. Accident
scenarios may be created through surveys of historical data,
consulting experts’ opinions, or performing risk analysis.
Structural crashworthiness of ships, oil outflow performance, and
residual strength of damaged ships can be estimated using simple
formulae, simplified analytical methods, or non-linear FEM
techniques of different complexity. Performance of a ship in an
accident can be measured by energy dissipation, penetration depth,
quantity of oil outflow or residual hull girder strength.
Acceptance criteria should be established on extensive comparative
studies, and provide a means for balancing numerous variables in
order to achieve an optimal solution.
