The reduction of the Arctic sea ice opens new shipping routes, necessitating advanced planning for safe navigation due to unpredictable ice conditions and severe weather. However, current Arctic route planning systems lack real-time adjustments and comprehensive consideration of the dynamic navigation environment. To address these limitations, we developed RouteView 2.0, an improved intelligent system for real-time operational planning for vessels on the Arctic Northeast Passage. This enhanced system features an intuitive interface that facilitates the extraction of independent floating ice, sea fog and sea spray icing conditions ahead of ships and incorporates these factors into the real-time optimization of operational planning. Additionally, the system's advanced visualization via Digital Twin improves situational awareness and decision-making by providing immersive 3D scenes of maritime elements. Performance tests show the system is practical and advisory.
