- Abstract
The International Maritime Organization (IMO) is responsible for regulating the design of oil tankers and other ships to provide for ship safety and environmental protection. Their ongoing transition to probabilistic performance-based standards requires the ability to predict the environmental performance and safety of specific ship designs. This is a difficult problem requiring the application of fundamental engineering principles and risk analysis. The serious consequence of ship collisions necessitates the development of regulations and requirements for the subdivision and structural design of ships so that damage and environmental pollution is reduced, and safety is improved. After a collision oil or other harmful substances may be spilled into the sea. It might even be possible for a ship to break apart and sink in a worst case scenario that includes failure of the structure of the ship. A numerical crash test was carried out in order to determine the aftermaths of a ship-jetty wall collision and to give hints to improve different ship structures. In combination with statistical data and determination of probabilities of the occurrence of different scenarios, safety assessment analysis can be carried out by certification agencies and administrative authorities. This paperwork develops a complete methodology for ship-to-jetty collision simulations using the explicit non-linear FE code ANSYS-LS-DYNA. The model was conceived in the explicit dynamics frame of work, the obtained results fully describing the complex phenomena associated with such catastrophic events.
