| Summary: | Source at https://iopscience.iop.org/journal/1757-899X . In a risk analysis we identify the causes that could lead to unwanted events/ outcomes. We introduce barriers that will reduce the probabilities of such events and also barriers that will mitigate the consequences of such events. Regarding Arctic Marine Transportation Challenges, more attention should be placed on communicating all work that is undertaken to enhance the safety and limit the environmental footprint of sailing along the Northern Sea Route. Training of personnel is, furthermore, undertaken in accordance with the requirements set to obtain Polar Code Certificates, and evacuation, escape and rescue exercises are regularly undertaken by vessel owners having vessels entering the area. Support is available for rescue operations and legal regulations is administrated by the Northern Sea Route Administration. Improved information on ice and ice-flow conditions are made available by an increased number of satellite observations. A steady improvement of all safety related features is ongoing. It is necessary to identify why the problems and the challenges are highlighted by the commercial actors, while the opportunities and savings are not that clearly presented. This paper will discuss a series of challenges for Arctic Marine Transportation and how these are being mitigated. Recommendations will be given regarding prioritizing of additional mitigation measures. Of key concern is the climate impact where the Northern Sea Route could be presented as a Green intercontinental transportation route in case use of heavy fuel oil is not permitted and by highlighting the support of icebreakers to ensure that schedules for all traffic can be kept and that safety during the transit is of key importance. The total climate imprint of using the Northern Sea Route should be compared to the imprint of sailing alternative routes and be communicated as a key opportunity for sustainable intercontinental sea transportation.
