Scenario-Based Assessment of Risks to Ice Class Ships

The rise in resource related projects in the Arctic has created the need for new approaches to assessing and minimizing risk. The new tankers and drill ships required for the Arctic will be larger and stronger than any previous ships, but will be very carefully designed and operated. The paper presents a methodology for assessing risk to large Arctic ships in a variety of scenarios. For the purpose of illustration of the approach, two ice collision scenarios are described.
