摘要：	With marine traffic in the Arctic on the rise, governments are expanding their maritime presence in the northern seaways and building capabilities to prevent accidents, support emergency responses, search and rescue, and to address issues related to national sovereignty. Despite the declining minimum extent of summer Arctic sea ice, there is still ice present throughout the year and deployments may be in areas infested with ice. Operators of naval ships that may be deployed to the Arctic need a sound methodology to understand the operational limitations of their assets in various ice conditions. Damaging a ship that has been sent to support and assist a response effort is not acceptable. This report provides an overview of several existing approaches for determining operational limitations of ships in various ice conditions. A detailed technical methodology is proposed to determine technical safe speeds for different ice conditions that is founded on modern principles of modeling ice-structure interaction. The focus is on government vessels that are lightly ice-strengthened, which may be required to operate in pack ice conditions as part of an emergency response effort. A case study is presented of a 5000 ton Ice Class PC5 Patrol Vessel to demonstrate the ice capability assessment procedure and the influence of key parameters.
