Funding Information: In order to have a holistic perspective and elements for the shipping system, the paper targets a comprehensive and long-term project specifically focusing on holistic safe polar shipping as the analysis basis. The long-term project has coherent focus and involves fundamental elements and holistic views towards safe polar shipping, thus provides a good basis for analysis. The polar project has two stages namely CEARCTIC (Centre of Excellence for Arctic Shipping and Operations) and CEPOLAR (Centre of Excellence for Scenario-based Risk Management in Polar Waters) starting from 2013 to 2022 focusing on different aspects regarding safe shipping in ice-covered waters. It is funded by Lloyd's Register Foundation and combines the research strengths from five universities: Aalto University, Hamburg University of Technology, Memorial University of Newfoundland, Norwegian University of Science and Technology and University of Helsinki. Extensive research work has been carried out in the framework of risk management towards safe shipping and the outcomes are mainly published in scientific journal and conference papers, where various subjects, research directions and methods have been focused and applied.Table 13 shows the toolbox under ecosystem impact topic. The model P3 adopts index-based approach to assess the vulnerability of Arctic biota. The resource and skill level needed are considered as medium and low respectively. The uncertainty is discussed to some extent; therefore, it is considered as a medium level SoE, which gives a M applicability level. The potential limitation is that the model still uses a number of judgements and uniform distribution due to lack of relevant data. In addition, the model does not include the spatial features for both oil spill and Arctic biota, which limits the practical utilization. The model P13 aims to estimate the probability of marine fish cell damages to oil spill. The required resource and skill level are low, and the model considers validation through a ...
