In the near future, new approaches related to increasing automation will change both ship design and maritime system-level design and operations. At the same time, growing interest in Arctic and Antarctic shipping activities due to the decreasing ice cover will also increase the risks of accidents on these waters.

The Centre of Excellence for Scenario-based Risk Management in Polar Waters (CEPOLAR) aims to tackle the issues associated with these new opportunities through guidelines that take a holistic view of the risks present in icy waters. The project is multidisciplinary, combining expertise in design methods, ice environment, ship-ice interaction, and structural damage and consequence analysis.

New rules for growing traffic

Demands for shipping in Arctic regions is increasing not only because of the increased volumes of gas and oil transported from Russia but also due to the use of the Northern Sea Route. When shipping moves more towards the North and South Pole, it brings with it an increased interest in the safety and sustainability of polar shipping, as well as in floating offshore installations operating in geographical areas with ice-infested waters.

Current rules and regulations for the design of ice- going ships are either deterministic or address risks in a way that is only partly based on performance. All accident-borne limit states are not properly considered by the IMO Polar Code or the IACS unified requirements for polar ships. This necessitates the development of goal-based regulations for ship safety and sea traffic.

Recommended practices will be developed to cover all key elements of polar ship design, namely:

  • Definition of ice conditions
  • Ship-ice contact characterisation
  • Limit state analysis of structures
  • Holistic risk/reward analysis for polar navigation and polar ship design

This development work is conducted in collaboration with key stakeholders from the international maritime industry.

The scope of this project is to develop guidelines for the safe and sustainable design of ice classed fleets by combining practical knowledge, state of the art engineering methods, and fundamental academic developments pertaining to the definition of safety levels at the early stages of ship design. To achieve the our goal, we study risks of Arctic operations by defining hazard scenarios and quantitatively estimating their impact (probability and consequences) of those at the concept design stage.

We focus on the behaviour of ships and structures in normal and extreme environments. We do our research by considering the safety of maritime transportation, as well as the experiences the marine environment can offer to cruise vessel passengers.
