The Polar Code, set in place by the International Maritime Organization (IMO), provides guidelines for ships navigating the challenging Polar regions. It classifies ships based on their design to withstand ice and gives them operational limits according to the Polar Operational Limit Assessment Risk Indexing System (POLARIS). However, while POLARIS gauges structural risk well, it doesn't fully consider the after-effects if a ship suffers ice damage. This paper introduces a new framework that adds to POLARIS by considering potential consequences, such as environmental harm or passenger safety, if a ship of a particular class incurs damage. The idea is simple: ships that, if damaged, might lead to more severe consequences should be operated even more cautiously. This updated framework aims to ensure the safety of everyone onboard and protect the Arctic's delicate environment. It emphasizes integrating current scientific studies with risk evaluation to better guide ship operations. By using this method, ships can make more informed decisions about their routes, ensuring safer and more responsible Arctic navigation.
