However, for designers to be able to fully implement the goal-based regulations of the Code, and to ensure compliance, relevant and validated design tools are needed. The Marine Technology research group at Aalto University, School of Engineering, has a long history on research related to the behavior of ships and structures in ice-covered waters, ice loads, ship performance and safety. The group studies these topics by conducting extensive full-and model-scale trials and by developing theoretical models for predicting ice loads, structural responses, and stochasticity, among others. Experiments are needed for understanding the mechanics of structure-wave-ice interactions, including the identification of key physical phenomena and process parameters. The group is also operating a unique experimental facility, namely the Aalto ice and wave tank, enabling model scale testing both in open water and various ice conditions. In this paper, we want to highlight some recent advancements based on the ongoing or recently finalized EU and Lloyd's Register (LR) Foundation funded projects: • Summary of the SEDNA Arctic Accident and Incident Database (AAID) which is a database containing information on maritime accidents and incidents in the Arctic. The database was compiled by the SEDNA project using data from primary and secondary sources from countries including Norway, Canada, and Russia. The database is described in more detail in (Bergström, et al., 2019). SEDNA (Safer waterborne transport and maritime operations) took place from 2017 to 2021. • Presentation of the outcome of the SEDNA risk-based design framework. The design framework aims to support goal/risk-based design of Arctic ships in agreement with the International Code for Ships Operating in Polar Waters (Polar Code). To this aim, the design framework integrates the regulations of the Polar Code into a holistic design process that also considers operational requirements and cost-efficiency (Bergström, et al., 2019). • Decision-making for winter navigation systems thus involves monitoring several parameters at both operational and system level, including multiple stochastic parameters. This part of the paper presents a new system level simulation model covering: (a) integration of ice characteristics, (b) operational level details of ships,and (c) system level details such as traffic flows and icebreaker scheduling. This work builds on the results of the WINMOS I and II projects. (Kulkarni et al., 2022). WINMOS I (Winter Navigation Motorways Of The Sea) took place 2014-2016 and WINMOS II 2016-2019. • Analysis of the challenges and future development of sustainable Arctic shipping. The results of the analysis revealed the need to extend the holistic ship design approach for sustainable optimization of Arctic vessels, e.g., considering future transport demands, new energy sources, and new technologies (Kondratenko et al., 2022). This work has been conducted as part of the LR Foundation funded CEPOLAR (Centre of Excellence for Scenario-based Risk Management in Polar Waters) project, which took place from 2013 until 2022.

N2 - Maritime activity in the Arctic is on the increase, driven by the extraction of natural resources, trans-Arctic shipping, and tourism. To manage the risks to humans and the polar environment, in 2017 the IMO enforced the International Code for Ships Operating in Polar Waters (Polar Code). The safety provisions of this Code are fundamentally goal-based, allowing designers to deviate from established prescriptive safety rules, facilitating design optimization and innovation. However, to enable goal-based design, ship designers need relevant and validated design tools. In this paper, we present examples of such tools, namely (a) accident statistics, (b) a framework for risk-based design of Arctic ships, (c) a simulation model of a winter navigation system, and (d) a sustainability assessment tool for Arctic shipping. The results are based on three different European Union funded research projects (SEDNA, WINMOS I/II), as well as on the Lloyd's Register Foundation funded project CEPOLAR.
